How Do You Calculate the Time Between Dates?

Count the calendar days from one date to another.

Example

Days between March 15 and July 4, 2026:

  • March 15-31 = 16 days
  • April = 30 days
  • May = 31 days
  • June = 30 days
  • July 1-4 = 4 days
  • Total = 111 days

Converting Days to Other Units

  • Weeks: days / 7 (111 days = 15 weeks 6 days)
  • Months (approx): days / 30.44 (111 days = ~3.6 months)
  • Years (approx): days / 365.25

Handling Leap Years

If your range includes February 29, add 1 extra day. Leap years: 2024, 2028, 2032...
