Weekend Days104
This day counter tells you how many days fall between two dates and splits that total into weekdays and weekend days. It is useful for counting down to an event, measuring a project span, or working out business days for billing and deadlines. An optional toggle includes the end date itself in the count when you want both endpoints counted.
Formula
totalDays = (end − start) [+1 if end included]; weekendDays = totalDays − weekdays(Mon–Fri)
- start, end
- The two dates being compared
- +1
- Added only when the end date itself is included in the count
- weekdays
- Count of Monday-through-Friday days in the span
How it works
- Enter a start date and an end date, then decide whether the end date should be counted by switching the "include end date" option.
- The tool computes the total number of days between the dates; if the end date is included it adds one more day to cover that final day.
- It then counts the Monday-to-Friday weekdays across the span and subtracts them from the total to report the weekend days separately.
Worked example
Counting the days from 1 January 2024 to 31 January 2024, without including the end date.
- Raw difference: 31 January − 1 January = 30 days.
- The end date is excluded, so the total stays at 30 days.
- Of those, 22 are weekdays, leaving 30 − 22 = 8 weekend days.
30 total days: 22 weekdays and 8 weekend days.
Frequently asked questions
- Should I include the end date?
- Include it when both the first and last day count, such as a hotel stay measured in nights versus days, or an inclusive event window. Leave it off when you want the gap between the dates rather than both endpoints.
- How are weekdays and weekend days defined?
- Weekdays are Monday through Friday, and weekend days are Saturday and Sunday. The counter does not account for public holidays, which vary by country and region.
- Can I count down to a future date?
- Yes. Set the start date to today and the end date to your event, and the total days tells you how long until it arrives. The order of the two dates does not change the absolute count.
- How is this different from a date calculator?
- A day counter totals and categorizes the days between two known dates. A date calculator instead takes one date and a span to add or subtract, producing a new resulting date.
