How to use the weekday counter
- Set the Start date and End date. Both dates are included.
- Choose the Weekday to count. It starts on Friday.
- Read the count, for example “Fridays: 52”, with the First and Last of those days in the range.
- Check Days in range (both dates included) and the table, Every weekday in the range, which runs Monday to Sunday.
What it does and when to use it
Some plans run on a single weekday. A Wednesday evening class, a Saturday market stall, a Monday team meeting, or a medicine taken every Sunday. The counter tells you how many sessions fit in a term, how many market days a season has, or how many Fridays of pay fall in a year. Because the first and last dates are listed, you can also see when the series starts and ends.
For all Monday-to-Friday working days with your own holidays and weekend, use the business days calculator. To check what weekday a single date falls on, try the day of the week finder. The days in month calculator lists the weekdays in every month of a year.
How it works
The tool finds the first date in the range that falls on your weekday by moving forward from the start date at most six days. From there, the count is how many full steps of 7 days fit before the end date, plus one. The last occurrence is found the same way, moving back from the end date. This is exact for any range, even thousands of years long, and uses plain calendar dates, so time zones do not matter.
Worked examples
Saturdays in 2027. Start 1 January, end 31 December 2027, weekday Saturday: 52, from 2 January to 25 December. The table shows Friday | 53, the only weekday with 53, because 2027 begins on a Friday.
Wednesday classes in an autumn term. Start Monday 7 September, end Friday 18 December 2026, weekday Wednesday: 15 sessions, beginning First: Wednesday, 9 September 2026 and ending on 16 December. Remove any half-term weeks yourself.
A leap February. Start 1 February, end 29 February 2028, weekday Tuesday: Tuesdays: 5, because 29 February 2028 is a Tuesday too. Every other weekday occurs 4 times that month.
Limits and tips
- The tool does not skip holidays or term breaks. Subtract them by hand, or split the range into parts.
- Dates must be valid and between years 1 and 9999.
