52 weeks + 1 day (or +2 in leap years)

years

52.1weeks

52 weeks + 1 day in a regular year. 52 weeks + 2 days in a leap year. (52 × 7 = 364, not 365)

💡This is why your birthday falls on a different day each year!

365 ÷ 7 = 52.14 weeks. That extra 0.14 = 1 day. Leap year: 366 ÷ 7 = 52.29 weeks = 2 extra days.

💡After 7 years, your birthday cycles back to the same day (roughly).

Weekly pay: 52 paychecks/year. Biweekly: 26 paychecks. Semi-monthly: 24 paychecks. Monthly: 12 paychecks.

💡Biweekly ≠ semi-monthly! Biweekly = every 2 weeks (26×), semi-monthly = twice a month (24×).

52 weeks - holidays - vacation = actual work weeks. Average US worker: ~48-50 work weeks/year.

💡Standard: 2080 work hours/year (40 hrs × 52 weeks).

52 × 7 = 364 days, but a year is 365 days. The extra 1-2 days cause dates to shift each year.

Typically 48-50 after subtracting holidays and vacation. 52 weeks × 40 hours = 2,080 potential work hours.

26 pay periods. Some years have 27 if the pay cycle aligns with extra days.
