What is a Year and a Microsecond?

A year is a unit of time based on the orbital period of Earth around the Sun. The word "year" derives from Old English gēar, Proto-Germanic jǣram, related to "to go" (referring to the Sun's apparent journey through the sky).

Types of Years

Tropical year (solar year):

365.2422 days (365 days, 5 hours, 48 minutes, 46 seconds)
Time between successive vernal equinoxes (spring returns)
Basis for Gregorian calendar (tracks seasons accurately)

Julian year (scientific standard):

Exactly 365.25 days = 31,557,600 seconds
Used in astronomy, physics for consistent conversions
Averages Julian calendar leap year cycle (3 × 365 + 1 × 366 ÷ 4)

Sidereal year:

365.2564 days (365 days, 6 hours, 9 minutes, 10 seconds)
Time for Earth to complete one orbit relative to fixed stars
~20 minutes longer than tropical year due to precession of equinoxes

Calendar year (Gregorian):

365 days (common year, 3 out of 4 years)
366 days (leap year, every 4 years with exceptions)
Average: 365.2425 days (97 leap years per 400 years)

Year Conversions (Julian Year = 365.25 days)

| Unit | Value | Calculation | |----------|-----------|-----------------| | Days | 365.25 | Standard definition | | Hours | 8,766 | 365.25 × 24 | | Minutes | 525,960 | 8,766 × 60 | | Seconds | 31,557,600 | 525,960 × 60 | | Weeks | 52.18 | 365.25 ÷ 7 | | Months | 12 | Standard calendar division |

A microsecond is a unit of time equal to one-millionth (1/1,000,000) of a second. It is also 1/1000th of a millisecond.

Note: The Year is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Microsecond belongs to the imperial/US customary system.

History of the Year and Microsecond

of the Year

1. Ancient Solar Observation (Pre-3000 BCE)

The concept of the year originated from observing seasonal cycles—the return of spring, flooding seasons, astronomical events (solstices, equinoxes).

Key observations:

Vernal equinox (spring): Day and night equal length (~March 20)
Summer solstice: Longest day (~June 21)
Autumnal equinox (fall): Day and night equal (~September 22)
Winter solstice: Shortest day (~December 21)
Tropical year: Time between successive vernal equinoxes = 365.24 days

Why critical? Agricultural societies needed to predict:

Planting seasons (spring planting window)
Flooding cycles (Nile River flooded annually June-September)
Harvest times (fall harvest before winter)
Animal migration patterns

2. Early Calendar Systems (3000-1000 BCE)

Egyptian Calendar (c. 3000 BCE):

365 days = 12 months × 30 days + 5 epagomenal days
No leap years = drifted ~1 day every 4 years = full cycle every 1,460 years (Sothic cycle)
Divided into 3 seasons: Inundation (Akhet), Growth (Peret), Harvest (Shemu)
Problem: Calendar drifted from actual seasons (harvest festivals gradually moved through calendar)

Babylonian Calendar (c. 2000 BCE):

Lunisolar: 12 lunar months (~354 days) + intercalary 13th month every 2-3 years
Metonic cycle (discovered ~432 BCE): 19 solar years ≈ 235 lunar months (7 intercalary months in 19 years)
Better seasonal alignment than pure lunar or 365-day solar calendar

Chinese Calendar (c. 1600 BCE):

Lunisolar: 12-13 months per year, intercalary months added algorithmically
Still used today for Chinese New Year (late January to mid-February)

Mesoamerican Calendars (c. 1000 BCE):

Haab (Maya civil calendar): 365 days = 18 months × 20 days + 5 unlucky days (Wayeb)
Tzolk'in (ritual calendar): 260 days = 13 numbers × 20 day names
Calendar Round: 52 Haab years = 73 Tzolk'in cycles (18,980 days)

3. Roman Calendar Evolution (753 BCE - 46 BCE)

Romulus Calendar (753 BCE - legendary):

10 months, 304 days, starting in March (spring equinox)
Winter gap (~61 days) unnamed = calendar chaos

Numa Pompilius Reform (c. 713 BCE):

Added January and February = 12 months, 355 days
Required intercalary month (Mercedonius) inserted periodically = political corruption
Calendar drifted severely (festivals months off from intended seasons)

Problem by 46 BCE: Calendar drifted ~3 months ahead of seasons (spring equinox in mid-summer)

4. Julian Calendar (46 BCE - 1582 CE)

Julius Caesar's reform (46 BCE):

Consulted Egyptian astronomer Sosigenes of Alexandria
365.25-day year: 365 days + leap day every 4 years (February 29)
46 BCE = "Year of Confusion" (445 days long) to realign calendar with seasons
January 1 established as New Year (previously March 1)

Julian leap year rule:

Every year divisible by 4 = leap year (e.g., 4, 8, 12, ... 2020, 2024)
Simple, systematic = dramatic improvement over irregular Roman intercalation

Problem with Julian calendar:

Tropical year = 365.2422 days (not exactly 365.25)
Julian calendar gains ~11 minutes per year = 3 days every 400 years
By 1582 CE: Calendar drifted 10 days ahead (vernal equinox on March 11 instead of March 21)

5. Gregorian Calendar (1582 CE - Present)

Pope Gregory XIII's reform (1582):

Goal: Restore vernal equinox to March 21 (for Easter calculation)
Correction: Removed 10 days (October 4, 1582 → October 15, 1582)
New leap year rule:
1. Year divisible by 4 = leap year (like Julian)
2. EXCEPT century years (1700, 1800, 1900, 2100) = NOT leap year
3. EXCEPT century years divisible by 400 (1600, 2000, 2400) = leap year
Result: 97 leap years per 400 years = 365.2425 days average
Accuracy: Only 27 seconds/year error = 1 day off every ~3,030 years

Why the reform?

Easter calculation: Christian Easter tied to vernal equinox (first Sunday after first full moon after March 21)
Julian drift moved equinox to March 11 = Easter dates increasingly inaccurate
Catholic Church needed calendar reform for liturgical calendar

Global adoption:

Catholic countries (Spain, Portugal, Italy, Poland): Immediately (October 1582)
Protestant countries: Resisted initially (religious conflict with Catholic Pope)
- Britain and colonies: 1752 (removed 11 days: Sept 2 → Sept 14)
- Germany (Protestant states): 1700 (removed 10 days)
Eastern Orthodox: 1900s (Russia 1918, Greece 1923)
Non-Christian countries: 20th century for civil purposes
- Japan: 1873 (Meiji era modernization)
- China: 1912 (Republic of China)
- Turkey: 1926 (Atatürk's secular reforms)
Now universal for international business, diplomacy, science

6. Modern Refinements and Proposals

Leap second (introduced 1972):

Earth's rotation gradually slowing (tidal friction from Moon)
Atomic clocks (SI second) vs. Earth's rotation = gradual drift
Leap second occasionally added (usually June 30 or December 31) to keep atomic time within 0.9 seconds of Earth rotation
27 leap seconds added 1972-2016 (~1 per 1.5 years average)

Failed calendar reform proposals:

World Calendar (1930s-1960s): 4 identical quarters, perpetual calendar (same dates always same day of week), extra "worldsday" outside week
International Fixed Calendar (early 1900s): 13 months × 28 days + 1 extra day (year day)
Opposition: Religious groups (Sabbath observance), businesses (calendar change costs), cultural inertia

Why Gregorian calendar persists despite imperfections:

Universal adoption = massive switching cost
"Good enough": 1-day error every 3,030 years = negligible for practical purposes
Cultural entrenchment: Decades, centuries, millennia aligned with current system

The microsecond is derived from the SI base unit, the second, using the metric prefix 'micro-', indicating a factor of 10⁻⁶. Its use became prevalent with the advent of electronic computers, radar technology, and high-speed photography.

Common Uses and Applications: years vs microseconds

Explore the typical applications for both Year (imperial/US) and Microsecond (imperial/US) to understand their common contexts.

Common Uses for years

and Applications

1. Age Calculation

Formula: Current year - Birth year = Age (approximate, adjust if birthday hasn't occurred yet)

Example 1: Born 1990, current year 2025

Age = 2025 - 1990 = 35 years old (if birthday already passed)
Age = 34 years old (if birthday hasn't occurred yet this year)

Precise age calculation:

Born: March 15, 1990
Today: January 10, 2025
Age = 2025 - 1990 - 1 = 34 years old (birthday hasn't passed yet, subtract 1)

Century calculation:

Born 1999: "90s kid" or "90s baby"
Born 2000-2009: "2000s kid"
Born 2010+: "2010s kid" or Gen Alpha

2. Interest and Investment Calculations

Simple interest (annual):

Formula: Interest = Principal × Rate × Time
Example: $10,000 at 5% APR for 3 years
- Interest = $10,000 × 0.05 × 3 = $1,500
- Total = $10,000 + $1,500 = $11,500

Compound interest (annual compounding):

Formula: Future Value = Principal × (1 + Rate)^Years
Example: $10,000 at 5% APY for 3 years
- FV = $10,000 × (1.05)³ = $10,000 × 1.157625 = $11,576.25

Rule of 72 (doubling time):

Formula: Years to double ≈ 72 ÷ Interest Rate
Example: 8% annual return → 72 ÷ 8 = 9 years to double
$10,000 at 8% → $20,000 in 9 years

3. Depreciation (Asset Value Decline)

Straight-line depreciation:

Formula: Annual Depreciation = (Cost - Salvage Value) ÷ Useful Life Years
Example: $30,000 car, $5,000 salvage, 5-year life
- Annual depreciation = ($30,000 - $5,000) ÷ 5 = $5,000/year
- Year 1: $30,000 - $5,000 = $25,000
- Year 2: $25,000 - $5,000 = $20,000

Accelerated depreciation:

Cars typically lose 20-30% value first year, then 15-20% annually
Electronics: Often lose 30-50% value first year

4. Project and Timeline Planning

Standard project durations:

1-year project: Long-term strategic initiative
Multi-year projects: Infrastructure (3-10 years), construction (2-5 years), software development (1-3 years)

Gantt charts and timelines:

Years as major milestones
Year 1: Planning and design
Year 2: Development and construction
Year 3: Testing and deployment
Year 4: Operations and maintenance

5. Insurance and Contracts

Insurance terms:

Term life insurance: 10-year, 20-year, 30-year terms
- Premiums locked for term duration
- Coverage expires at end of term unless renewed
Auto insurance: 6-month or 1-year policies (renewed annually/semi-annually)
Health insurance: 1-year open enrollment period (select plan for following year)

Employment contracts:

1-year contract: Fixed-term employment (common for contractors, academics)
Multi-year contracts: Athletes (3-5 year contracts), executives (2-4 years)
Non-compete clauses: Often 1-2 years after leaving company

Leases:

Apartment leases: 1-year standard (12 months)
Commercial leases: 3-10 years typical
Car leases: 2-4 years (24-48 months)

6. Statistical and Data Analysis

Time series data:

Annual data points: GDP growth rate (year-over-year), population (annual census estimates)
Trend analysis: "5-year moving average" smooths short-term fluctuations

Year-over-year (YoY) comparisons:

Formula: YoY Growth = (This Year - Last Year) ÷ Last Year × 100%
Example: Revenue $10M (2023) → $12M (2024)
- YoY growth = ($12M - $10M) ÷ $10M × 100% = 20% YoY growth

Compound Annual Growth Rate (CAGR):

Formula: CAGR = (Ending Value ÷ Beginning Value)^(1/Years) - 1
Example: Revenue $10M (2020) → $15M (2025) = 5 years
- CAGR = ($15M ÷ $10M)^(1/5) - 1 = 1.5^0.2 - 1 = 0.0845 = 8.45% CAGR

7. Warranty and Guarantee Periods

Product warranties:

Electronics: 1-year manufacturer warranty (e.g., Apple 1-year limited warranty)
Appliances: 1-2 years parts and labor
Cars: 3-year/36,000-mile bumper-to-bumper, 5-year/60,000-mile powertrain
Home construction: 1-year builder warranty (workmanship), 10-year structural

Service guarantees:

Software licenses: 1-year subscription (renewable)
Extended warranties: 2-5 years beyond manufacturer warranty

When to Use microseconds

Computing: Measuring instruction execution times in older processors, interrupt latency, bus transfer times.
Physics: Duration of certain chemical reactions, some nuclear events, timing in particle accelerators.
Electronics: Defining pulse widths in digital signals, measuring signal delays in circuits.
Biology: Duration of nerve impulses, time scale for certain enzymatic reactions.
Everyday: The flash duration of a typical camera strobe is a few microseconds.

Additional Unit Information

About Year (yr)

1. How many days are in a year?

It depends on the type of year:

Common year (Gregorian): 365 days (occurs 3 out of 4 years)
Leap year (Gregorian): 366 days (occurs every 4 years, with exceptions)
Julian year (scientific standard): Exactly 365.25 days
Tropical year (astronomical): 365.2422 days (365 days, 5 hours, 48 minutes, 46 seconds)
Gregorian average: 365.2425 days (97 leap years per 400 years)

For most conversions: Use 365.25 days (Julian year standard).

2. What is a leap year?

Leap year: Year with 366 days instead of 365, adding February 29 (leap day).

Gregorian leap year rule:

Year divisible by 4 → leap year (e.g., 2024, 2028)
EXCEPT century years (1700, 1800, 1900, 2100) → NOT leap year
EXCEPT century years divisible by 400 (1600, 2000, 2400) → leap year

Why leap years?

Tropical year = 365.2422 days (not exactly 365)
Without leap years: Calendar drifts ~1 day every 4 years = 25 days every century
Leap years keep calendar aligned with seasons

Next leap years: 2024, 2028, 2032, 2036, 2040, 2044, 2048

3. Why is 365.25 days often used for a year in calculations?

365.25 days = Julian year, the scientific standard for conversions and calculations.

Calculation: Average of Julian calendar leap year cycle

3 common years (365 days each) + 1 leap year (366 days) = 1,461 days
1,461 days ÷ 4 years = 365.25 days/year

Advantages:

Exact value (no decimals beyond 2 places)
Simple calculations: Multiply by 365.25 for day conversions
Scientific standard: Used in astronomy, physics, engineering
Defined precisely: 1 Julian year = 31,557,600 seconds exactly

When to use 365.25: General conversions, scientific calculations, multi-year projections.

When NOT to use: Specific date calculations (use actual calendar with leap years).

4. How many seconds are in a year?

Julian year (365.25 days):

1 year = 365.25 days × 24 hours/day × 60 minutes/hour × 60 seconds/minute
1 year = 365.25 × 86,400 seconds/day
1 year = 31,557,600 seconds exactly

Tropical year (365.2422 days):

365.2422 × 86,400 = 31,556,925.2 seconds (astronomical year)

Common year (365 days):

365 × 86,400 = 31,536,000 seconds

Leap year (366 days):

366 × 86,400 = 31,622,400 seconds

Standard answer: 31,557,600 seconds (Julian year).

5. What is the difference between calendar year and fiscal year?

Calendar year:

January 1 - December 31
Standard Gregorian calendar year
Used for personal taxes (US), general dating, most non-business contexts

Fiscal year (FY):

Any 12-month accounting period chosen by organization for financial reporting
Often NOT January-December
Allows companies to align reporting with business cycles

Common fiscal years:

US federal government: October 1 - September 30 (FY2025 = Oct 2024-Sep 2025)
UK government: April 1 - March 31
Retailers: Often end January 31 (includes holiday season)
Universities: Often July 1 - June 30 (aligns with academic year)

Why different fiscal years?

Seasonal businesses: Retailers want holiday sales (Nov-Dec) mid-year, not at year-end (accounting complexity)
Budgeting cycles: Governments approve budgets before fiscal year starts
Tax planning: Align fiscal year with tax advantages

6. How old am I in years?

Simple formula: Current year - Birth year (adjust if birthday hasn't passed)

Precise calculation:

Subtract birth year from current year
If current date < birthday this year, subtract 1

Example 1:

Born: June 15, 1995
Today: October 20, 2025
Age = 2025 - 1995 = 30 (birthday already passed in 2025) → 30 years old

Example 2:

Born: November 10, 1995
Today: October 20, 2025
Age = 2025 - 1995 - 1 = 29 (birthday hasn't passed yet in 2025) → 29 years old

Programming formula:

age = current_year - birth_year
if (current_month < birth_month) OR (current_month == birth_month AND current_day < birth_day):
    age = age - 1

7. What is the tropical year vs. sidereal year?

Tropical year (solar year):

365.2422 days (365 days, 5 hours, 48 minutes, 46 seconds)
Time between successive vernal equinoxes (spring returns)
Basis for Gregorian calendar (tracks seasons)
What we use for civil calendar

Sidereal year:

365.2564 days (365 days, 6 hours, 9 minutes, 10 seconds)
Time for Earth to complete one orbit relative to fixed stars
~20 minutes (~0.014 days) longer than tropical year

Why the difference?

Precession of equinoxes: Earth's rotational axis wobbles (like spinning top)
Axis completes full wobble every ~25,800 years (Platonic year)
Vernal equinox drifts westward ~50 arcseconds per year relative to stars
Result: Tropical year (season-based) slightly shorter than sidereal year (star-based)

Which to use?

Tropical year: Calendar purposes (Gregorian calendar tracks seasons)
Sidereal year: Astronomy (tracking Earth's orbit relative to stars)

8. Why did the Gregorian calendar replace the Julian calendar?

Problem with Julian calendar:

Julian year = 365.25 days (365 days + leap day every 4 years)
Tropical year = 365.2422 days
Difference: 365.25 - 365.2422 = 0.0078 days/year = ~11 minutes/year
Drift: 3 days every 400 years

Impact by 1582:

Calendar drifted 10 days ahead of seasons (1,257 years × 11 min/year ≈ 10 days)
Vernal equinox on March 11 instead of March 21
Easter calculation increasingly inaccurate (tied to vernal equinox)

Gregorian solution:

Removed 10 days immediately (Oct 4, 1582 → Oct 15, 1582)
New leap year rule: Skip 3 leap years every 400 years (century years not divisible by 400)
Result: 365.2425 days/year average (97 leap years per 400 years)
Error: Only 27 seconds/year = 1 day off every ~3,030 years

Success: Gregorian calendar now universal for civil purposes worldwide.

9. What are decade, century, and millennium?

Decade:

10 years
Examples: 1990s (1990-1999), 2020s (2020-2029)
Casual usage: Often refers to cultural/generational period

Century:

100 years
20th century = 1901-2000 (NOT 1900-1999, because no year 0)
21st century = 2001-2100 (NOT 2000-2099)
Notation: "19th century" or "1800s" (informal)

Millennium:

1,000 years
1st millennium = 1-1000 CE
2nd millennium = 1001-2000 CE
3rd millennium = 2001-3000 CE
Y2K (Year 2000) celebrated new millennium, but technically started 2001

Why century/millennium boundaries confusing?

No year 0 in Gregorian calendar (1 BCE → 1 CE)
1st century = years 1-100 (not 0-99)
Centuries numbered one ahead of their "hundreds digit" (1900s = 20th century)

10. How many hours/minutes are in a year?

Julian year (365.25 days):

Hours: 365.25 days × 24 hours/day = 8,766 hours
Minutes: 8,766 hours × 60 minutes/hour = 525,960 minutes
Seconds: 525,960 minutes × 60 seconds/minute = 31,557,600 seconds

Common year (365 days):

Hours: 365 × 24 = 8,760 hours
Minutes: 8,760 × 60 = 525,600 minutes (famous from musical "Rent": "525,600 minutes, how do you measure a year?")

Leap year (366 days):

Hours: 366 × 24 = 8,784 hours
Minutes: 8,784 × 60 = 527,040 minutes

Standard answer: 8,766 hours or 525,960 minutes (Julian year).

11. What is a leap second?

Leap second: Extra second occasionally added to Coordinated Universal Time (UTC) to keep atomic time synchronized with Earth's rotation.

Why needed?

Atomic clocks (SI second): Extremely precise, constant
Earth's rotation: Gradually slowing (tidal friction from Moon ~2 milliseconds per century)
Drift: Atomic time gradually diverges from Earth's actual rotation
Solution: Add leap second when difference approaches 0.9 seconds

Implementation:

Usually added June 30 or December 31
Clock reads: 23:59:59 → 23:59:60 → 00:00:00 (extra second)
27 leap seconds added 1972-2016 (~1 every 1.5 years)
No leap seconds 2017-present (Earth's rotation hasn't required it)

Controversy:

Causes computer system problems (software doesn't expect 60-second minutes)
Proposed abolition: Let atomic time and Earth rotation drift, adjust in larger increments decades later

12. How do I convert years to other units?

Quick conversion formulas (Julian year = 365.25 days):

Years to days:

days = years × 365.25
Example: 3 years = 3 × 365.25 = 1,095.75 days

Years to weeks:

weeks = years × 52.18 (365.25 ÷ 7)
Example: 2 years = 2 × 52.18 = 104.36 weeks

Years to months:

months = years × 12
Example: 5 years = 5 × 12 = 60 months

Years to hours:

hours = years × 8,766 (365.25 × 24)
Example: 1 year = 8,766 hours

Years to seconds:

seconds = years × 31,557,600 (365.25 × 86,400)
Example: 1 year = 31,557,600 seconds

Years to decades/centuries:

decades = years ÷ 10
centuries = years ÷ 100
