How it works
The first matching day is found by counting forward from the start date to the chosen weekday. After that, matching days repeat every seven days, so the count is the number of seven-day steps that fit before the end date, plus one.
Both dates are counted when they match, as long as the end date is not before the start date.
Worked example
Between 2026-01-01 and 2026-12-31 there are 52 days that fall on a Saturday.
Questions
Are both end dates included?
Yes. The start and end dates are both counted if they fall on the weekday you picked.
How do I count weekends?
Count Saturdays and Sundays separately, then add the two totals together.
Can I count a whole year?
Yes. Use January 1 as the start date and December 31 as the end date.
