How it works

days = end − start

Each date is turned into a day number on the calendar, and the difference is the number of days between them. By default the start day counts and the end day doesn’t, the way you’d count nights in a hotel; switch on “include the end date” to count both. Weekdays skip Saturdays and Sundays but not public holidays.

  1. Subtract the start date from the end date Tuesday, November 10, 2026 − Thursday, January 1, 2026 = 313 days
  2. Divide by 7 for weeks 313 ÷ 7 = 44.71 weeks
