About Year (365 days) (yr)
Definition
The common year is a unit of time equal to 365 days, or 31,536,000 seconds.
Mathematical Relationship
1 yr = 365 d = 8,760 h = 525,600 min = 31,536,000 s. A leap year has 366 days (31,622,400 s).
Conversion Formula
To convert years to days: multiply by 365 (or 365.25 for average including leap years). To seconds: multiply by 31,536,000.
Practical Applications
Age calculation, financial year reporting, contract durations, academic years, and historical timeline reference.
Interesting Facts
The year 2000 was a leap year (divisible by 400), but 1900 was not (divisible by 100 but not 400). The Gregorian rule fixes the calendar's drift to 1 day per 3,236 years.
Common Mistakes
Assuming every 4th year is a leap year — century years must be divisible by 400 (so 1900 wasn't a leap year).
Educational Tips
Leap year rule: divisible by 4 = leap, UNLESS divisible by 100, UNLESS also divisible by 400. So 2000 was, 1900 wasn't.
About Week (wk)
Definition
The week is a unit of time equal to 7 days, or 604,800 seconds.
Mathematical Relationship
1 wk = 7 d = 168 h = 10,080 min = 604,800 s. A year has about 52.18 weeks.
Conversion Formula
To convert weeks to days: multiply by 7. To convert weeks to hours: multiply by 168.
Practical Applications
Pay periods (biweekly), pregnancy tracking (40 weeks), sprint cycles in agile development, and workout schedules.
Interesting Facts
The seven-day week has no astronomical basis — unlike days, months, and years, it's a purely human invention. It has been continuous for thousands of years.
Common Mistakes
Assuming months are exactly 4 weeks — most months are 4.3 weeks (30–31 days). Only February in non-leap years is exactly 4 weeks.
Educational Tips
Days of the week in many languages reflect the seven celestial bodies: Sun-day, Moon-day, Saturn-day, etc.
