How to use the Weekday Counter

  1. Pick the start and end dates. The order doesn't matter.
  2. Tick the weekdays to count, for example Monday only, or Saturday and Sunday for weekends.
  3. Choose whether the start and end dates count. Both are included by default.
  4. Read the total and see how many of each weekday the range holds.
  5. Scroll the list of dates or download it as CSV for planning.

The weekday counting formula

For an inclusive range of N days: full weeks = ⌊N ÷ 7⌋ and leftover = N mod 7. Every weekday occurs once per full week. The leftover days are the first leftover weekdays starting from the weekday of the first date, and each gets one extra.

Example: 1 March to 31 March 2026 is 31 days = 4 weeks + 3 days. 1 March 2026 is a Sunday, so Sunday, Monday and Tuesday occur 5 times and every other weekday 4 times.

A month has 28 to 31 days, so each weekday appears 4 or 5 times. In a 31-day month, three weekdays appear 5 times; in a 30-day month, two; in a 29-day February, one; in a 28-day February, none.

Handy uses

  • Classes and lessons: count the Tuesdays and Thursdays in a term to plan sessions.
  • Pay and bills: see how many Fridays (paydays) fall in a month or year; months with 5 Fridays are worth knowing for biweekly budgets.
  • Shifts and rotas: count weekend days to share them fairly.
  • Events: list every first-to-last Sunday market date and download it.

Frequently asked questions

How do I count how many Mondays are between two dates?

Count the days in the range and divide by 7. Each weekday appears once per full week, and the leftover days (0 to 6) add one more to the weekdays they land on. For example, 1 January to 31 December 2026 is 365 days = 52 weeks + 1 day; that extra day is a Thursday, so 2026 has 53 Thursdays and 52 of every other weekday.

How many of each weekday are in a year?

A common year has 365 days, which is 52 weeks and 1 day, so one weekday occurs 53 times: the weekday of 1 January. A leap year has 366 days, so two weekdays occur 53 times: those of 1 and 2 January.

Are the start and end dates included?

Yes by default, because people usually mean 'from this date through that date'. Untick either option to leave that date out of the count.

Can I count several weekdays at once?

Yes. Tick any combination, such as Tuesday and Thursday for a class schedule or Saturday and Sunday for weekends. The total adds them together, and the table still shows each weekday separately.

How is this different from a business days calculator?

A business days calculator counts working days and usually skips holidays. This tool counts specific days of the week, such as only Wednesdays, and lists each date, without treating any day as a holiday.

How many weekends are left this year?

Tick Saturday and Sunday and set the end date to 31 December. The result is the number of weekend days; divide by 2 for complete weekends (the first or last may be a single day).
