Frequently Asked Questions
Why is 52 weeks 364 days, not 365?
52 × 7 = 364, but a year is 365 days (or 366 in leap years). The extra day is why your week-day birthday shifts forward by 1 each year (or 2 days after a leap year). 52 weeks = 364 days; 1 year ≈ 52 weeks + 1 day.
How many weeks in a typical month?
Approximately 4.33 weeks per average month (30.44 days / 7). Calendar months range 4-5 weeks: 28-day February = exactly 4 weeks; 30-day month = 4 weeks + 2 days; 31-day month = 4 weeks + 3 days. Pay periods for biweekly schedules use 26 paychecks/year (52 ÷ 2).
