Weekday Counter
Enter two dates to see exactly how many Mondays, Tuesdays, Fridays — every day of the week — fall in that range, all at once.
How this is calculated
The calculator walks every date from your start date to your end date, inclusive of both, and tallies how many fall on each day of the week. That's different from a single weekday-vs-weekend split — it answers the more specific "how many Mondays" or "how many Fridays" question directly, for pay periods, class schedules, or anything else that repeats on a particular weekday rather than every weekday.
Not the same as a weekday/weekend split
The Business Days Calculator and Weekends Between Dates tools group every date into just two buckets: weekday or weekend. This tool goes one level more specific — it breaks a date range down into all seven individual days of the week, so you can answer questions like "how many Fridays are left this year" or "how many Tuesdays are in this quarter" without counting a calendar by hand.
Frequently asked questions
Does this count both the start and end date?
Yes — this calculator counts every date in the range inclusively, including both the start and end date, since that's how most "how many Mondays" questions are meant.
Why is the total one more than Days Between Dates gives me?
This tool counts inclusively (both endpoints included), while Days Between Dates counts only the full calendar days elapsed between two dates. A range that starts and ends on the same date differs by exactly one under the two conventions — the same reason a week "Monday through Sunday" is 7 days, not 6.
What is this useful for?
Pay periods and shift schedules that repeat on specific weekdays, class schedules, project timelines, and any question shaped like "how many Fridays are left this year" or "how many Mondays in this quarter."
