The Fourteen-Day Period
A fortnight is precisely 14 consecutive days, representing two full weeks.
Exact equivalents:
- 14 days (by definition)
- 336 hours (14 days × 24 hours)
- 20,160 minutes (336 hours × 60 minutes)
- 1,209,600 seconds (20,160 minutes × 60 seconds)
Not variable: Unlike months (28-31 days), the fortnight is always exactly 14 days, making it a consistent scheduling unit.
Etymology: Counting by Nights
The word "fortnight" combines:
- "Fourteen" (the number 14)
- "Night" (from Old English "niht")
Old English origin: "Fēowertīene niht" = "fourteen nights"
Why nights, not days? Ancient Germanic peoples observed the lunar cycle for timekeeping. The moon's visibility at night made nights more prominent for tracking time than daylight periods. This night-counting tradition appears in related Germanic languages:
- Dutch: "veertien dagen" (fourteen days) — shifted from nights to days
- German: "vierzehn Tage" (fourteen days) — also shifted to days
- Icelandic: "fj
ógur dagar" (fourteen days)
English uniquely preserves the "night" etymology, though modern usage refers to the complete 14-day period regardless of time of day.
Relationship to Weeks and Months
Two weeks: A fortnight is exactly half a lunar month (~29.5 days ÷ 2 ≈ 14.75 days), though slightly shorter. This makes it a natural intermediate period between the week (7 days) and the month.
Calendar months:
- 26-27 fortnights per year (365.25 days ÷ 14 = 26.09 fortnights)
- ~2.17 fortnights per month (30.44 days ÷ 14)
The fortnight provides a convenient subdivision smaller than a month but larger than a week, useful for payroll, rent, and recurring obligations.
A century is a unit of time equal to 100 consecutive years. The word derives from Latin "centum" (one hundred).
Duration in Other Units
1 century equals:
- 100 years (exactly)
- 10 decades (100 ÷ 10)
- 1,200 months (100 × 12)
- ~5,217 weeks (100 × 52.17)
- 36,524 days (100 common years) or 36,525 days (accounting for ~25 leap years)
- Average: 36,525 days (100 × 365.25)
- 876,600 hours (36,525 × 24)
- 52,596,000 minutes (876,600 × 60)
- 3,155,760,000 seconds (52,596,000 × 60)
Century Boundaries: The 1 vs. 0 Debate
Formal reckoning (technically correct):
- 1st century: 1-100 CE
- 18th century: 1701-1800
- 19th century: 1801-1900
- 20th century: 1901-2000
- 21st century: 2001-2100
Why? Because there was no year 0 in the Gregorian calendar (1 BCE → 1 CE directly), the first century was years 1-100, not 0-99.
Popular usage (dominant in practice):
- 18th century: "The 1700s" (1700-1799)
- 19th century: "The 1800s" (1800-1899)
- 20th century: "The 1900s" (1900-1999)
- 21st century: "The 2000s onward" (2000-2099)
Reality: Popular usage dominates. When people say "20th century," they typically mean 1900-1999, not 1901-2000. The millennium celebration happened January 1, 2000, not January 1, 2001, despite formal correctness.
Note: The Fortnight is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Century belongs to the imperial/US customary system.
History of the Fortnight and Century
Ancient Germanic Night-Counting (Pre-9th Century)
Lunar observation: Before written calendars, Germanic tribes tracked time using the moon's phases. The new moon to full moon cycle (approximately 14-15 days) created natural fortnight-length periods.
Night prominence:
- Full moons illuminated nights, making them memorable markers
- Daylight periods blurred together without distinct markers
- Nights were counted: "three nights hence," "fourteen nights from now"
This system influenced Old Norse, Old English, and other Germanic languages.
Old English Documentation (9th-11th Centuries)
Anglo-Saxon Chronicle (circa 890 CE): The earliest written English historical record uses "fēowertīene niht" to describe fourteen-day periods in battle accounts and political events.
Beowulf (8th-11th century): The epic poem references time periods measured in nights, including fortnight-length durations for journeys and feasts.
Legal codes: Anglo-Saxon law codes (Aethelberht, Alfred the Great) used fortnights for legal waiting periods and court summons.
Middle English Evolution (12th-15th Centuries)
Spelling variations:
- "Fourtenyght" (14th century)
- "Fourtenight" (15th century)
- "Fourteenyght"
- Gradual simplification toward "fortnight"
Chaucer's Canterbury Tales (1387-1400): Geoffrey Chaucer used fortnight references, solidifying the term in literary English: "And eek me thynketh in my remembraunce, / I have herd telle of a fortnyght or thre"
Medieval commerce: Markets and fairs often operated on fortnight cycles, with merchants returning to towns every two weeks.
Early Modern English (16th-17th Centuries)
Standardization: By the 1500s, "fortnight" became the dominant spelling and pronunciation.
Shakespeare's usage (1590s-1610s): William Shakespeare used "fortnight" frequently across his plays:
- The Tempest (1611): "I'll deliver all; And promise you calm seas, auspicious gales, And sail so expeditious that shall catch Your royal fleet far off. My Araby, chick! That is thy charge: then to the elements Be free, and fare thou well! Please you, draw near." (References to travel time in fortnights)
- The Two Gentlemen of Verona
- Much Ado About Nothing
Shakespeare's widespread influence ensured "fortnight" became standard educated English.
British Empire and Commonwealth Spread (17th-19th Centuries)
Colonial administration: British colonial governments used fortnightly reporting cycles, payment schedules, and administrative periods.
Spread to:
- Australia (colonized 1788 onward)
- New Zealand (colonized 1840 onward)
- India (British Raj, 18th-20th centuries)
- Canada (though later influenced by American "two weeks")
- South Africa, Caribbean, East Africa
Embedded in law: Colonial legal codes, rental agreements, and labor contracts specified fortnightly terms, creating lasting institutional usage.
Industrial Revolution and Labor Movements (19th Century)
Fortnightly wages: British factories and mills established fortnightly pay cycles during the Industrial Revolution (1760-1840):
- Workers received wages every two weeks
- Easier for employers to manage than weekly payroll
- Allowed workers to budget for monthly rent
Labor union influence: Trade unions negotiated fortnightly pay as standard, spreading throughout the British Empire.
Australian adoption: Australian colonies (becoming a federation in 1901) adopted fortnightly wages widely. Today, Australia has the world's highest fortnight usage, with most wages, rent, and bills calculated fortnightly.
American Divergence (20th Century)
"Two weeks" replaces "fortnight": American English gradually abandoned "fortnight" during the 20th century in favor of "two weeks."
Reasons:
- Simplicity: "Two weeks" is more transparent to non-native speakers
- Bi-weekly confusion: "Bi-weekly" can mean either twice per week or once every two weeks, causing ambiguity
- Cultural shift: American preference for straightforward terminology
Result: By the 21st century, "fortnight" sounds archaic or quaint to most Americans.
Modern Commonwealth Usage (1900s-Present)
United Kingdom: Fortnightly payroll, magazine publications ("published fortnightly"), TV schedules (reality shows with "fortnightly evictions").
Australia and New Zealand:
- Dominant time unit: Wages almost universally paid fortnightly
- Rental agreements: Rent calculated per fortnight (not per week or month)
- Government benefits: Welfare payments issued fortnightly
Cultural persistence: Despite global influence of American English, fortnight remains deeply embedded in Commonwealth life, appearing daily in conversation, media, and official documents.
of the Century Concept
1. Ancient Origins: Roman Centuria (509 BCE - 27 BCE)
Roman military organization:
- Centuria (plural: centuriae) = Roman military unit of approximately 100 soldiers (later reduced to 80)
- Led by a centurion (centurio)
- Latin "centum" = one hundred
- 6 centuries = 1 cohort; 10 cohorts = 1 legion (~6,000 soldiers)
Early timekeeping:
- Romans used Ab urbe condita (AUC, "from the founding of the city") dating from Rome's legendary founding (753 BCE)
- No systematic use of "century" for 100-year periods yet
- Time organized by consulships, reigns, dynasties
2. Calendar Development and Anno Domini Dating (1 CE - 1582 CE)
Anno Domini (AD) system:
- Dionysius Exiguus (c. 525 CE): Calculated years from Jesus Christ's birth
- Introduced Anno Domini (AD, "in the year of the Lord") dating
- Critical error: No year 0 (went directly from 1 BCE to 1 CE)
- This creates century boundary confusion still debated today
Julian Calendar (46 BCE - 1582 CE):
- Julius Caesar introduced 365.25-day year (leap year every 4 years)
- Provided stable framework for long-term chronology
- Enabled systematic dating of events over centuries
Gregorian Calendar Reform (1582 CE):
- Pope Gregory XIII corrected Julian calendar drift
- Established modern calendar system still used today
- Removed 10 days (October 4, 1582 → October 15, 1582)
- Century years divisible by 400 are leap years (1600, 2000), others not (1700, 1800, 1900)
3. Renaissance and Enlightenment: Historical Periodization (1400s-1700s)
Systematic historiography emerged:
- 15th-16th centuries: Renaissance scholars developed historical chronologies
- 17th-18th centuries: Enlightenment historians systematized century-based periodization
- Edward Gibbon (Decline and Fall of the Roman Empire, 1776-1789): Used century-scale analysis
Why centuries became standard:
- Generational scale: ~4 generations per century = intergenerational change visible but comprehensible
- Administrative records: Tax records, census data, government documents accumulated over centuries
- Pattern recognition: 100-year scale reveals structural changes invisible in decade-scale analysis
- Round number psychology: Base-10 counting makes 100-year periods psychologically satisfying
Periodization labels emerged:
- "The 16th century" = 1500s Renaissance, Reformation
- "The 17th century" = 1600s Scientific Revolution, Baroque
- "The 18th century" = 1700s Age of Enlightenment, Industrial Revolution begins
4. 19th Century: Century as Historical Framework (1801-1900)
The "long 19th century" concept:
- Historians sometimes define as 1789-1914 (French Revolution to WWI)
- Captures coherent historical era despite not matching formal century boundaries
Major 19th-century transformations:
- Industrial Revolution (1760-1840): Steam power, factories, railroads
- Urbanization: Rural → urban population shift
- Imperialism: European colonial empires peak
- Scientific progress: Darwin, Maxwell, Mendel
- Political revolutions: 1848 Revolutions, unification of Germany/Italy
- Technological: Telegraph, telephone, photography, electricity
Century consciousness:
- People in 1800s increasingly thought in century-scale terms
- "The spirit of the 19th century" = common phrase
- Fin de siècle (end of century, 1890s-1900s) = cultural movement
5. 20th Century: Century of Extremes (1901-2000)
Eric Hobsbawm's "short 20th century" (1914-1991):
- WWI start to Soviet Union collapse
- Captures coherent historical narrative despite formal century boundaries
Major 20th-century transformations:
- World Wars: WWI (1914-1918), WWII (1939-1945)
- Ideological conflict: Fascism, Communism, Capitalism compete
- Cold War (1947-1991): US vs. USSR, nuclear arms race
- Decolonization: European empires disintegrate (1940s-1970s)
- Technological revolutions:
- Automobiles, airplanes (early 1900s)
- Nuclear energy (1940s)
- Computers (1940s-1950s)
- Space exploration (1950s-1960s)
- Internet (1990s)
- Mobile phones (1990s-2000s)
- Population explosion: 1.6 billion (1900) → 6.1 billion (2000)
- Medical advances: Antibiotics, vaccines, life expectancy doubled
- Environmental: Climate change, ozone depletion, biodiversity loss
Century labeling:
- "The American Century" (Henry Luce, 1941): US dominance of 20th century
- "The People's Century" (BBC, 1995): Mass politics, democracy spread
6. 21st Century: Digital Age and Beyond (2001-Present)
Millennium transition debate:
- Popular celebration: January 1, 2000 (Y2K)
- Formal start: January 1, 2001
- Most people celebrated 2000 despite pedantic correctness
21st-century defining features (so far):
- 9/11 attacks (2001): "War on Terror" begins
- Digital revolution: Smartphones ubiquitous (iPhone 2007)
- Social media: Facebook, Twitter, Instagram, TikTok
- Climate crisis: Accelerating global warming, extreme weather
- COVID-19 pandemic (2020-2023): Global disruption
- AI revolution: ChatGPT (2022), generative AI breakthroughs
- Geopolitical shifts: Rise of China, multipolar world
- Economic: 2008 Financial Crisis, wealth inequality
"21st-century skills": Digital literacy, critical thinking, adaptability
Common Uses and Applications: fortnights vs centuries
Explore the typical applications for both Fortnight (imperial/US) and Century (imperial/US) to understand their common contexts.
Common Uses for fortnights
1. British and Commonwealth Payroll
Fortnightly pay period: The most widespread use of fortnight is in employment contracts specifying pay every 14 days.
Advantages:
- 26 pay periods per year (simpler arithmetic than 52 weekly periods)
- Budget-friendly: Easier to align with monthly bills
- Payroll efficiency: Reduces administrative burden compared to weekly pay
Typical schedule: Employees paid on alternating Fridays, creating a predictable two-week cycle.
2. Australian Rental Agreements
Rent calculation: Australian rental market uniquely quotes rent per fortnight rather than per week or per month.
Conversion formulas:
- Fortnight to month: Fortnight rent × 26 ÷ 12
- Month to fortnight: Month rent × 12 ÷ 26
Example:
- $700/fortnight = $700 × 26 ÷ 12 = $1,516.67/month
3. Scheduling and Planning
Recurring events: "The committee meets fortnightly" = every two weeks
Vacation planning: "I'm taking a fortnight off" = two-week vacation
Project timelines: "Deliver progress reports every fortnight"
4. Literary and Formal Writing
British literature: Historical novels and formal writing use "fortnight" for period flavor.
Legal documents: UK contracts may specify "a fortnight's notice" for resignations or terminations.
5. Sports and Competition Schedules
Tournament cycles: Some sports competitions use fortnightly rounds.
Training schedules: Athletes may follow fortnight-based training cycles (two weeks of intensive training followed by recovery).
6. Historical and Cultural Context
Period dramas: Films and TV set in Britain use "fortnight" for authenticity.
Example dialogue: "The Duke will return in a fortnight."

Additional Unit Information
About Fortnight (fn)
How many days are in a fortnight?
Exactly 14 days.
A fortnight is always 14 consecutive days, equivalent to two full weeks (7 days × 2).
Time equivalents:
- 336 hours
- 20,160 minutes
- 1,209,600 seconds
How many weeks make a fortnight?
Exactly 2 weeks = 1 fortnight.
This is the definition of the term: "fortnight" literally means "fourteen nights" (two weeks).
Where does the word "fortnight" come from?
From Old English "fēowertīene niht" (fourteen nights).
Etymology:
- "Fēowertīene" = fourteen
- "Niht" = night
Historical context: Ancient Germanic peoples counted time by nights rather than days, observing lunar cycles. The fortnight represents approximately half a lunar month (~29.5 days ÷ 2).
Evolution: Old English "fēowertīene niht" → Middle English "fourtenyght" → Modern English "fortnight"
Is "fortnight" commonly used everywhere?
No—usage is heavily geographic.
Common in:
- United Kingdom (standard term)
- Ireland (standard term)
- Australia (most common time unit for pay/rent)
- New Zealand (standard term)
- Other Commonwealth nations (varying frequency)
Rare in:
- United States (sounds archaic; "two weeks" preferred)
- Canada (mixed usage; more American influence)
Result: "Fortnight" is standard British/Commonwealth English but virtually unused in American English.
What's the difference between fortnight and bi-weekly?
Fortnight = unambiguous 14-day period
Bi-weekly = ambiguous; two possible meanings:
- Every two weeks (synonymous with fortnightly)
- Twice per week
Recommendation: Use "fortnight" or "every two weeks" to avoid confusion. "Bi-weekly" can mislead readers.
Example:
- Ambiguous: "Bi-weekly payroll" (twice per week or every two weeks?)
- Clear: "Fortnightly payroll" (unambiguous: every 14 days)
How many fortnights are in a year?
Approximately 26.09 fortnights per year.
Calculation: 365.25 days (average year with leap years) ÷ 14 days = 26.089 fortnights
Payroll standard: Employers use 26 pay periods for fortnightly wages, slightly underestimating the true annual length (creates an extra day or two per year).
How do I convert monthly rent to fortnightly rent?
Formula: Fortnight rent = Monthly rent × 12 ÷ 26
Example:
- Monthly rent: $1,500
- $1,500 × 12 ÷ 26 = $692.31 per fortnight
Reverse (fortnight to month): Monthly rent = Fortnight rent × 26 ÷ 12
Example:
- Fortnight rent: $700
- $700 × 26 ÷ 12 = $1,516.67 per month
Is a fortnight half a month?
Approximately, but not exactly.
Fortnight: 14 days (fixed)
Half month: Varies by month
- February: 14 days (coincidentally equal!)
- January, March, May, July, August, October, December: 15.5 days
- April, June, September, November: 15 days
Average half month: 30.44 ÷ 2 = 15.22 days (8.7% longer than fortnight)
Conclusion: Fortnight ≈ half month, but they're distinct concepts.
Why do Australians use fortnights so much?
Historical and practical reasons:
1. British colonial influence: Australia inherited British administrative and commercial systems, including fortnightly wage cycles.
2. Payroll alignment: Fortnightly wages became standard, so rent, bills, and budgeting adapted to match pay cycles.
3. Mathematical convenience: 26 fortnights per year simplifies annual calculations compared to 52 weeks.
4. Cultural entrenchment: Generations of Australians have grown up with fortnightly systems, making it the natural default.
Result: Australia likely uses "fortnight" more frequently than any other nation, including the UK.
Do Americans understand "fortnight"?
Most recognize it, but few use it.
Recognition:
- Americans encounter "fortnight" in British literature, period dramas, and historical contexts
- Educated Americans know it means "two weeks"
Usage:
- Virtually never used in everyday American speech
- Sounds archaic, old-fashioned, or excessively formal
Recommendation: When addressing American audiences, use "two weeks" instead of "fortnight" to ensure clarity.
About Century (c)
1. How many years are in a century?
Exactly 100 years. The word "century" comes from Latin "centum" (one hundred).
Other units:
- 1 century = 100 years = 10 decades = 1,200 months = ~36,525 days
2. When did the 21st century begin?
Formal answer: January 1, 2001 (because there was no year 0, the 1st century was years 1-100, so the 21st century is 2001-2100).
Popular answer: January 1, 2000 (most people celebrated the new millennium in 2000, and colloquially refer to "the 2000s" as the start of the 21st century).
Reality: Both are used; formal definition is technically correct, but popular usage dominates in practice.
3. Why is the 1800s called the 19th century?
Because of how centuries are numbered:
- 1st century = years 1-100
- 2nd century = years 101-200
- 18th century = years 1701-1800
- 19th century = years 1801-1900 (the "1800s")
- 20th century = years 1901-2000 (the "1900s")
Rule: Century number = (hundreds digit + 1). So 1800s → century 18+1 = 19th century.
4. How many generations are in a century?
Approximately 4-5 generations, assuming ~20-25 years per generation.
Calculation:
- If generation = 25 years → 100 ÷ 25 = 4 generations per century
- If generation = 20 years → 100 ÷ 20 = 5 generations per century
Example: Great-great-grandparents often lived in a different century than you.
5. Is a century a standard unit in science?
No. The century is not part of the International System of Units (SI). The SI base unit for time is the second.
Scientific time units:
- Years (Julian year = 365.25 days exactly)
- Kiloyears (kyr): 1,000 years
- Megayears (Myr): 1,000,000 years
- Gigayears (Gyr): 1,000,000,000 years
Century usage: Common in history, demography, climate science, but not formal SI unit.
6. How many days are in a century?
Approximately 36,525 days (accounting for leap years).
Calculation:
- 100 years × 365 days = 36,500 days
- Plus ~25 leap days per century = 36,525 days total
Exact number varies: Depends on leap year distribution (Gregorian calendar: 97 leap years per 400 years).
7. What is the difference between centennial and bicentennial?
Centennial: 100th anniversary (1 century)
Bicentennial: 200th anniversary (2 centuries)
Other -ennial terms:
- Sesquicentennial: 150th anniversary (1.5 centuries)
- Tercentennial/Tricentennial: 300th anniversary (3 centuries)
- Quadricentennial: 400th anniversary (4 centuries)
- Quincentennial: 500th anniversary (5 centuries)
8. Can a person live in three different centuries?
Yes, but extremely rare.
Requirements:
- Born in one century (e.g., 1898, 19th century)
- Live through next century (1900s, 20th century)
- Live into third century (2000s, 21st century)
- Requires living 102+ years if born in last years of century
Example: Born December 1898 (19th century) → lived through 20th century (1901-2000) → died January 2001 (21st century) = lived in 3 centuries despite being only 102 years old.
9. What is a "long century" in history?
Historical concept: Period longer than 100 years but representing a coherent historical era.
Famous examples:
- "Long 19th century" (1789-1914): French Revolution to WWI start
- "Long 18th century" (1688-1815): Glorious Revolution to Waterloo
- "Short 20th century" (1914-1991): Conversely, WWI to USSR collapse = only 77 years but captures coherent era
Why useful: Historical eras don't align neatly with formal century boundaries; "long/short century" captures thematic unity.
10. How do I calculate how many centuries between two years?
Formula: centuries = (ending year - starting year) ÷ 100
Examples:
- 1500 to 2000: (2000 - 1500) ÷ 100 = 5 centuries (500 years)
- 1776 to 2024: (2024 - 1776) ÷ 100 = 2.48 centuries (~248 years)
- 1900 to 2100: (2100 - 1900) ÷ 100 = 2 centuries (200 years)
11. What is "fin de siècle"?
French phrase: "End of the century" (literally "end of era")
Historical meaning: Cultural period at end of 19th century (1890s-1900s) characterized by:
- Cultural pessimism mixed with optimism
- Decadence, Art Nouveau
- Anxiety about modernity
- Transition into new century
Modern usage: Any "end of century" cultural moment (Y2K was modern "fin de siècle").
12. How many centuries in a millennium?
10 centuries = 1 millennium
Conversions:
- 1 century = 0.1 millennia (100 years)
- 5 centuries = 0.5 millennia (500 years)
- 10 centuries = 1 millennium (1,000 years)
