A month is a unit of time used with calendars, approximately based on the orbital period of the Moon around Earth. The word "month" derives from "Moon" (Proto-Germanic mǣnōth).
Modern Gregorian Calendar Months
In the Gregorian calendar (standard worldwide since 1582), months have irregular lengths:
| Month | Days | Hours | Weeks (approx) | |-----------|----------|-----------|-------------------| | January | 31 | 744 | 4.43 | | February | 28 (29 leap) | 672 (696 leap) | 4.00 (4.14 leap) | | March | 31 | 744 | 4.43 | | April | 30 | 720 | 4.29 | | May | 31 | 744 | 4.43 | | June | 30 | 720 | 4.29 | | July | 31 | 744 | 4.43 | | August | 31 | 744 | 4.43 | | September | 30 | 720 | 4.29 | | October | 31 | 744 | 4.43 | | November | 30 | 720 | 4.29 | | December | 31 | 744 | 4.43 |
Average Month for Conversions
For mathematical conversions, an average month is defined as:
- 1/12th of a year = 365.25 days ÷ 12 = 30.4375 days (often rounded to 30.44 days)
- 730.5 hours (30.4375 × 24)
- 43,830 minutes (730.5 × 60)
- 2,629,800 seconds (43,830 × 60)
- 4.35 weeks (30.4375 ÷ 7)
Lunar Month vs. Calendar Month
- Synodic month (lunar cycle, new moon to new moon): 29.53 days (29 days, 12 hours, 44 minutes, 3 seconds)
- Sidereal month (Moon's orbit relative to stars): 27.32 days
- Gregorian calendar month: 28-31 days (avg 30.44 days)
- Drift: Calendar months drift ~2 days per month from lunar phases
A Shake is an informal unit of time equal to 10 nanoseconds (10 ns), or 10⁻⁸ seconds. It is primarily used in nuclear physics and astrophysics to measure the timing of events in nuclear reactions and related phenomena.
Note: The Month is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Shake belongs to the imperial/US customary system.
History of the Month and Shake
of the Month
1. Ancient Lunar Origins (Pre-3000 BCE)
The concept of the month originated from observing the lunar cycle—the period from one new moon to the next, approximately 29.53 days (synodic month).
Early lunar calendars:
- Babylonian calendar (c. 2000 BCE): 12 lunar months (~354 days per year), with periodic intercalary (13th) months added every 2-3 years to realign with seasons
- Egyptian calendar (c. 3000 BCE): 12 months of exactly 30 days each (360 days) + 5 epagomenal days = 365 days, detached from lunar cycle
- Hebrew/Jewish calendar (c. 1500 BCE): Lunisolar calendar with 12-13 months (29-30 days each), still used today for religious observances
- Chinese calendar (c. 1600 BCE): Lunisolar calendar with 12-13 months, determining Chinese New Year (late January to mid-February)
Why lunar months? Ancient civilizations without artificial lighting noticed the Moon's dramatic visual changes every ~29.5 days, making it an obvious natural timekeeper.
2. Roman Calendar Evolution (753 BCE - 46 BCE)
The Roman calendar underwent dramatic transformations:
Romulus Calendar (753 BCE - legendary):
- 10 months, 304 days total, starting in March (spring equinox)
- Months: Martius (31), Aprilis (30), Maius (31), Junius (30), Quintilis (31), Sextilis (30), September (30), October (31), November (30), December (30)
- Winter gap (~61 days) was unnamed, creating calendar chaos
Numa Pompilius Reform (c. 713 BCE):
- Added January and February to fill winter gap
- 12 months, 355 days total (still 10.25 days short of solar year)
- Required periodic intercalary months (Mercedonius) to realign with seasons
- Romans disliked even numbers, so most months had 29 or 31 days (February got unlucky 28)
Late Roman Republic (c. 100 BCE):
- Calendar administration corrupt—priests (pontifices) manipulated intercalary months for political gain (extending terms, delaying elections)
- Calendar drifted months out of sync with seasons (harvest festivals in wrong seasons)
3. Julian Calendar (46 BCE - 1582 CE)
Julius Caesar's reform (46 BCE):
- Consulted Egyptian astronomer Sosigenes of Alexandria
- Adopted solar year = 365.25 days (365 days + leap day every 4 years)
- Redesigned month lengths to solar-based 28-31 days:
- 31 days: January, March, May, July (Quintilis), September, November
- 30 days: April, June, August (Sextilis), October, December
- 28/29 days: February (unlucky month, kept short)
- 46 BCE = "Year of Confusion" (445 days long to realign calendar with seasons)
Later adjustments:
- 44 BCE: Quintilis renamed July (Julius Caesar, after his assassination)
- 8 BCE: Sextilis renamed August (Augustus Caesar)
- August given 31 days (stealing 1 from February) to match July's prestige, redistributing others
- Final pattern: Jan(31), Feb(28/29), Mar(31), Apr(30), May(31), Jun(30), Jul(31), Aug(31), Sep(30), Oct(31), Nov(30), Dec(31)
Problem with Julian calendar: Solar year = 365.2422 days (not exactly 365.25), so calendar gained ~11 minutes per year = 3 days every 400 years
4. Gregorian Calendar (1582 CE - Present)
Pope Gregory XIII's reform (1582):
- Corrected drift: Removed 10 days (October 4, 1582 → October 15, 1582) to realign with seasons
- New leap year rule:
- Leap year every 4 years (like Julian)
- EXCEPT century years (1700, 1800, 1900) NOT leap years
- EXCEPT century years divisible by 400 (1600, 2000, 2400) ARE leap years
- Result: 97 leap years per 400 years = 365.2425 days average (only 27 seconds/year error)
- Month lengths unchanged from final Julian pattern
Adoption:
- Catholic countries (Spain, Portugal, Italy): Immediately (1582)
- Protestant countries (Britain, colonies): 1752 (removed 11 days: Sept 2 → Sept 14)
- Russia: 1918 (removed 13 days, after October Revolution became November Revolution)
- China: 1912 (Republic of China adoption)
- Turkey: 1926 (secular reforms)
- Now universal for civil purposes worldwide
5. Lunar Calendars Continue
Despite Gregorian dominance, lunar/lunisolar calendars continue for religious/cultural purposes:
- Islamic Hijri calendar: 12 lunar months (354-355 days), cycles through seasons every 33 years, determines Ramadan
- Hebrew calendar: Lunisolar with 12-13 months, determines Jewish holidays
- Chinese calendar: Lunisolar, determines Chinese New Year, Mid-Autumn Festival
- Hindu calendars: Multiple regional lunisolar systems
- Buddhist calendars: Various lunisolar systems across Thailand, Sri Lanka, Myanmar
The term "Shake" originated during the Manhattan Project, the World War II effort to develop the first nuclear weapons. Nuclear chain reactions happen extremely quickly, and physicists needed a convenient, short unit of time to discuss the timing of events within these reactions. Ten nanoseconds was chosen as a practical order of magnitude for many processes involved. The name itself is informal, reputedly derived from the expression "two shakes of a lamb's tail," implying a very short duration.
Common Uses and Applications: months vs shakes
Explore the typical applications for both Month (imperial/US) and Shake (imperial/US) to understand their common contexts.
Common Uses for months
and Applications
1. Financial Planning and Budgeting
Monthly budget framework:
- Income: Track monthly take-home pay (after taxes)
- Fixed expenses: Rent/mortgage, car payment, insurance (consistent monthly amounts)
- Variable expenses: Groceries, utilities, entertainment (varies month-to-month)
- Savings goals: "Save $500/month" = $6,000/year
- Debt repayment: "Extra $200/month toward credit card" = $2,400/year payoff
Monthly vs. annual thinking:
- $150/month subscription = $1,800/year (psychological impact: monthly feels smaller)
- "Latte factor": $5 daily coffee = $150/month = $1,800/year = $18,000/decade
Monthly financial ratios:
- Rent rule: Rent should be ≤30% of monthly gross income
- 50/30/20 rule: 50% needs, 30% wants, 20% savings (monthly breakdown)
2. Subscription and Membership Economy
Monthly Recurring Revenue (MRR) = business model foundation:
- SaaS (Software as a Service): Monthly subscription pricing (e.g., Adobe Creative Cloud $54.99/month)
- Streaming services: Netflix, Spotify, Disney+ (monthly billing standard)
- Gym memberships: Monthly dues (e.g., $30-100/month depending on gym)
- Amazon Prime: $14.99/month (or $139/year = $11.58/month, annual cheaper)
Monthly vs. annual pricing psychology:
- Annual = higher upfront cost, lower monthly rate, customer lock-in
- Monthly = lower barrier to entry, higher churn risk, higher effective rate
3. Project Management and Milestones
Standard project durations:
- 1-month sprint: Agile/Scrum often uses 2-4 week sprints (close to 1 month)
- 3-month project: Standard short-term project (1 quarter)
- 6-month project: Medium-term initiative (2 quarters, half-year)
- 12-month project: Long-term strategic initiative (full year)
Monthly milestones:
- Month 1: Planning and setup
- Month 2: Development/implementation
- Month 3: Testing and refinement
- Month 4: Launch and monitoring
4. Employment and Compensation
Pay period variations:
- Monthly (12 pay periods/year): Common internationally, especially Europe/Asia
- Pros: Aligns with monthly bills, simpler accounting
- Cons: Long gap between paychecks (especially if month has 31 days)
- Semi-monthly (24 pay periods/year): 1st and 15th of each month
- Pros: More frequent pay (twice per month), aligns with mid-month expenses
- Cons: Pay dates vary (weekends/holidays), inconsistent days between paychecks
- Bi-weekly (26 pay periods/year): Every 2 weeks (e.g., every other Friday)
- Pros: Consistent day of week, 2 "extra" paychecks per year
- Cons: Doesn't align with monthly bills, some months have 3 paychecks
Monthly salary vs. hourly:
- Salaried: Annual salary ÷ 12 = monthly salary (e.g., $72,000/year = $6,000/month)
- Hourly: (Hourly rate × hours/week × 52 weeks) ÷ 12 months (e.g., $25/hr × 40hrs × 52 ÷ 12 = $4,333/month)
5. Calendar Organization
Month as primary calendar unit:
- Monthly view: Standard calendar layout (7 columns × 4-6 rows = 28-42 cells)
- Month numbering: January = 1, February = 2, ... December = 12
- Date notation:
- US: MM/DD/YYYY (month first)
- International (ISO 8601): YYYY-MM-DD (year-month-day)
- European: DD/MM/YYYY (day first)
Month-based planning:
- Goals: "Read 2 books per month" = 24 books/year
- Habits: "Exercise 3 times per week" = 12-13 times per month
- Reviews: "Monthly review" of goals, finances, habits
6. Seasonal Business Cycles
Retail calendar:
- January: Post-holiday sales, fitness equipment (New Year's resolutions)
- February: Valentine's Day
- March-April: Spring cleaning, Easter, tax season
- May: Mother's Day, Memorial Day (unofficial summer start)
- June: Father's Day, graduations, weddings
- July-August: Summer travel, back-to-school shopping (late August)
- September: Labor Day, fall season begins
- October: Halloween
- November: Thanksgiving, Black Friday (biggest shopping day)
- December: Holiday shopping season (Christmas/Hanukkah)
Quarterly thinking (3-month periods):
- Q1 (Jan-Mar): New Year momentum, tax season
- Q2 (Apr-Jun): Spring/early summer, end of fiscal year for many companies
- Q3 (Jul-Sep): Summer slowdown, back-to-school
- Q4 (Oct-Dec): Holiday season, year-end push, budget planning
7. Age and Developmental Milestones
Infant/child development:
- 0-12 months: Tracked monthly (dramatic changes each month)
- 3 months: Lifts head, smiles
- 6 months: Sits up, starts solid foods
- 9 months: Crawls, says "mama/dada"
- 12 months: Walks, first words
- 12-24 months: Often still tracked monthly ("18 months old" vs. "1.5 years")
- 2+ years: Typically switch to years ("3 years old")
Age expression:
- Months (0-23 months): More precise for developmental tracking
- Years (2+ years): Standard for most purposes
- Decades (30s, 40s, etc.): Rough life stages
When to Use shakes
The Shake is almost exclusively used in specific technical fields:
- Nuclear Physics: Measuring the time intervals between successive neutron generations in a nuclear chain reaction.
- Astrophysics: Discussing timescales relevant to certain high-energy astrophysical events.
- Particle Physics: Occasionally used in experiments involving very short-lived particles or interactions.
- Laser Physics: Sometimes used in contexts involving very short laser pulses.
It is not used for everyday time measurements.
Additional Unit Information
About Month (mo)
1. How many days are in a month?
It varies by month:
- 31 days: January, March, May, July, August, October, December (7 months)
- 30 days: April, June, September, November (4 months)
- 28 days: February (non-leap year)
- 29 days: February (leap year, every 4 years with exceptions)
Average month = 30.44 days (365.25 ÷ 12), used for conversions.
Mnemonic: "30 days hath September, April, June, and November. All the rest have 31, except February alone, which has 28 days clear, and 29 in each leap year."
Knuckle trick: Make fists and count across knuckles (31 days) and valleys (30 days, except February).
2. Why do months have different lengths?
Historical reasons:
- Roman calendar origins: 10-month calendar (Romulus) had 304 days, leaving ~61-day winter gap
- Numa Pompilius added January and February (c. 713 BCE), creating 12 months with 355 days
- Julius Caesar (46 BCE): Julian calendar with 365.25-day year required distributing days across 12 months
- Political decisions: July (Julius Caesar) and August (Augustus Caesar) both given 31 days for prestige, shortening February to 28 days
Result: Irregular pattern (31-28-31-30-31-30-31-31-30-31-30-31) due to Roman politics, not astronomy.
3. What is an average month length used for conversions?
Average month = 30.4375 days (often rounded to 30.44 days)
Calculation: 365.25 days per year ÷ 12 months = 30.4375 days per month
- 365.25 accounts for leap year (365 × 3 years + 366 × 1 year = 1,461 days ÷ 4 years = 365.25)
When to use average month:
- Converting months to days/weeks/hours when specific month unknown
- Financial calculations (monthly interest rates, annual salary ÷ 12)
- Age approximations ("6 months old" ≈ 183 days)
When NOT to use average: Specific date calculations (use actual month lengths).
4. Is a month based on the Moon?
Historically, yes. Currently, only approximately.
Etymology: "Month" derives from "Moon" (Old English mōnað, Proto-Germanic mǣnōth).
Lunar cycle: 29.53 days (synodic month, new moon to new moon)
Gregorian calendar month: 28-31 days (avg 30.44 days)
- Drift: Calendar months drift ~2 days per month from lunar phases
- Example: Full moon on January 15 → next full moon ~February 13 (29.5 days later), not February 15
Modern lunar calendars:
- Islamic calendar: Strictly lunar (12 months × 29.5 days = 354 days), cycles through seasons every 33 years
- Hebrew/Chinese calendars: Lunisolar (12-13 months, adding extra month every 2-3 years to stay aligned with seasons)
Why detached? Solar year (365.24 days) and lunar year (354.37 days) are incompatible—12 lunar months = 10.87 days short of solar year.
5. How many weeks are in a month?
Average month = 4.35 weeks (30.44 days ÷ 7 days/week)
Common mistake: Assuming 1 month = 4 weeks (WRONG—actually 4 weeks = 28 days, most months are 30-31 days)
Specific months:
- 28 days (February, non-leap) = 4.00 weeks
- 29 days (February, leap) = 4.14 weeks
- 30 days (April, June, September, November) = 4.29 weeks
- 31 days (January, March, May, July, August, October, December) = 4.43 weeks
Implications:
- "4 weeks pregnant" ≠ "1 month pregnant" (4 weeks = 28 days, 1 month avg = 30.44 days)
- "Save $100/week" = $435/month (not $400)
6. How many months are in a year?
12 months in all major calendar systems (Gregorian, Julian, Hebrew, Chinese, Hindu).
Why 12 months?
- Lunar approximation: 12 lunar cycles (~354 days) close to solar year (365 days)
- Convenient division: 12 has many factors (1, 2, 3, 4, 6, 12), making quarters (3 months), half-years (6 months) easy
- Historical precedent: Babylonian, Roman calendars used 12 months
Alternative proposals (failed):
- French Republican Calendar (1793-1805): 12 months × 30 days + 5 epagomenal days (abandoned after Napoleon)
- International Fixed Calendar (proposed 1930s): 13 months × 28 days + 1 extra day (never adopted, opposed by religious groups)
7. What is a leap year and how does it affect months?
Leap year: Year with 366 days (not 365), adding 1 extra day to February (29 days instead of 28).
Leap year rule (Gregorian calendar):
- Year divisible by 4 = leap year (e.g., 2024)
- EXCEPT century years (1700, 1800, 1900) = NOT leap year
- EXCEPT century years divisible by 400 (1600, 2000, 2400) = leap year
Why leap years? Solar year = 365.2422 days (not exactly 365), so calendar gains ~0.2422 days per year = ~1 day every 4 years. Adding leap day keeps calendar aligned with seasons.
Impact on months:
- Only February affected (28 → 29 days)
- Leap year: 366 days = 52 weeks + 2 days (52.29 weeks)
- Non-leap year: 365 days = 52 weeks + 1 day (52.14 weeks)
Next leap years: 2024, 2028, 2032, 2036, 2040
8. What is the origin of month names?
Month names (Gregorian calendar, from Latin):
| Month | Origin | Meaning | |-----------|-----------|-------------| | January | Janus (Roman god) | God of beginnings, doorways (two faces looking forward/backward) | | February | Februa (Roman purification festival) | Purification ritual held mid-February | | March | Mars (Roman god) | God of war (originally first month of Roman year) | | April | Aprilis (Latin) | "To open" (buds opening in spring) or Aphrodite (Greek goddess) | | May | Maia (Roman goddess) | Goddess of growth, spring | | June | Juno (Roman goddess) | Goddess of marriage, queen of gods | | July | Julius Caesar | Roman dictator (month of his birth), originally Quintilis ("fifth") | | August | Augustus Caesar | First Roman emperor, originally Sextilis ("sixth") | | September | Septem (Latin) | "Seven" (originally 7th month before January/February added) | | October | Octo (Latin) | "Eight" (originally 8th month) | | November | Novem (Latin) | "Nine" (originally 9th month) | | December | Decem (Latin) | "Ten" (originally 10th month) |
Historical shift: September-December originally matched their numeric names (7th-10th months) when Roman year started in March. Adding January/February shifted them to 9th-12th positions.
9. Why is February the shortest month?
Roman superstition and politics:
- Roman numerology: Romans considered even numbers unlucky, so most months had 29 or 31 days (odd numbers)
- February = unlucky month: Month of purification rituals (Februa), associated with death/underworld, so Romans kept it short
- Julius Caesar's reform (46 BCE): Distributed days to create 365.25-day year, February remained shortest at 28 days
- Augustus's adjustment (8 BCE): Legend says Augustus took 1 day from February (29 → 28) to make August 31 days (matching July), but historians dispute this—likely just continued existing pattern
Result: February = 28 days (29 in leap years), shortest month by 1-3 days.
10. What are the financial quarters?
Financial quarters (Q1, Q2, Q3, Q4): 3-month periods dividing the fiscal year for business reporting.
Calendar year quarters:
- Q1 = January, February, March (90/91 days)
- Q2 = April, May, June (91 days)
- Q3 = July, August, September (92 days)
- Q4 = October, November, December (92 days)
Fiscal year variations: Many companies/governments use different fiscal years:
- US federal government: Oct 1 - Sep 30 (Q1 = Oct-Dec)
- UK government: Apr 1 - Mar 31 (Q1 = Apr-Jun)
- Japan/India: Apr 1 - Mar 31
- Australia: Jul 1 - Jun 30
Why quarters? Balance between frequent reporting (not too infrequent like annual) and manageable workload (not too frequent like monthly for major reporting).
11. How do I calculate age in months?
Formula: (Current year - Birth year) × 12 + (Current month - Birth month)
Example 1: Born March 15, 2020, today is June 15, 2024
- (2024 - 2020) × 12 + (6 - 3) = 4 × 12 + 3 = 51 months old
Example 2: Born November 20, 2022, today is January 10, 2024
- (2024 - 2022) × 12 + (1 - 11) = 2 × 12 - 10 = 14 months old
Precision note: Calculation above assumes same day of month. For exact age:
- If current day ≥ birth day: Use formula above
- If current day < birth day: Subtract 1 month (haven't reached full month yet)
When to use months for age:
- 0-23 months: Infant/toddler development changes rapidly monthly
- 24+ months: Typically switch to years ("2 years old" not "24 months old")
12. What's the difference between bi-monthly and semi-monthly?
Confusing terminology:
Bi-monthly = Ambiguous (avoid using)
- Meaning 1: Every 2 months (6 times per year)
- Meaning 2: Twice per month (24 times per year)
Semi-monthly = Twice per month (24 times per year)
- Example: Paycheck on 1st and 15th of each month
- 12 months × 2 = 24 pay periods per year
Bi-weekly = Every 2 weeks (26 times per year, not 24)
- Example: Paycheck every other Friday
- 52 weeks ÷ 2 = 26 pay periods per year
Recommendation: Avoid "bi-monthly" (ambiguous). Use "every 2 months" (6×/year) or "twice per month"/"semi-monthly" (24×/year).
About Shake (shake)
How long is a Shake in seconds?
One Shake is equal to 10 nanoseconds (10 ns), which is 10⁻⁸ seconds, or 0.00000001 seconds.
Where did the name "Shake" come from?
The name is an informal term coined during the Manhattan Project. It's believed to be a humorous reference to the phrase "in two shakes of a lamb's tail," signifying a very brief period, appropriate for the rapid events in nuclear reactions.
Is the Shake an SI unit?
No, the Shake is not part of the International System of Units (SI). The standard SI unit for time is the second (s). The Shake is a specialized, informal unit used within specific scientific communities for convenience.
