Day Counter
Find out exactly how many days fall between two dates, including or excluding the end date, plus a weekday and weekend breakdown.
Example
From March 1, 2026 to March 15, 2026 with the end date excluded, there are 14 days — made up of 10 weekdays and 4 weekend days (2 weeks).
How it works
Days are computed from the difference between the two dates in milliseconds divided by 86,400,000 (ms per day); the end date adds 1 to the count when "include end date" is on. Weekdays count Monday–Friday and weekends count Saturday–Sunday across the counted span.
Good to know
The Day Counter measures the gap between any two calendar dates and shows it four ways at once: the total number of days, how many of those fall on weekdays, how many land on the weekend, and the equivalent number of weeks. It is built for anyone who needs a quick, exact span rather than a rough mental estimate — project managers tracking sprint length, travelers totting up trip nights, landlords and tenants checking a rental window, or anyone counting down to a deadline, due date, or anniversary.
The detail that makes it more than a simple subtraction is the weekday-versus-weekend split. Because it walks through every single day in the range and checks the day of the week, it tells you how many working days versus rest days sit inside the span — useful when only business days actually matter, such as estimating turnaround on a task or how many billable days a stretch of calendar contains.
To read the result, set your two dates and pick whether the end date should be counted. The big number is your day total, the three stats beneath break it into weekdays, weekend days, and weeks (weeks is just the total divided by seven, so it can show a decimal), and the note line confirms which counting mode is active.
- Tip: if you accidentally enter the later date first, the tool quietly swaps them and uses the absolute difference, so a negative number will never appear — but watch the note line, which flags when this swap happened so you can confirm the order was intentional.
Frequently asked questions
What is the difference between including and excluding the end date?
Excluding the end date counts only the days from the start up to (but not counting) the end date — useful for durations like a rental period. Including the end date adds one day so both the start and end days are counted, which is handy for inclusive event spans.
How are weekdays and weekend days counted?
Each counted day is checked for its day of the week. Saturday and Sunday are tallied as weekend days, while Monday through Friday are tallied as weekdays, so the two figures always add up to the total days between.

People also ask
How do I count the number of days between two dates?
Enter a start date and an end date, and the tool instantly shows the total days between them. By default it excludes the end date, so you can toggle 'Include end date' if you want both endpoints counted.
Does the day count include the start date and the end date?
The start date is always the beginning of the span and the end date is excluded by default, meaning the first day is counted but the last is not. Switching to 'Include end date' adds one day so both the start and end days are included in the total.
How many weekdays are between two dates?
The Day Counter shows a 'Weekdays' figure that tallies every Monday through Friday inside your selected range. This is helpful when only working days count, such as estimating business-day turnaround or billable days.
Why does the weeks number show a decimal?
The weeks value is simply the total days divided by seven, so any span that is not an exact multiple of seven shows a fractional result. For example, 10 days displays as roughly 1.43 weeks.
What happens if the end date is earlier than the start date?
The tool automatically swaps the two dates and uses the absolute difference, so you still get a positive day count. A note appears confirming that the end date came before the start date so you can double-check the order.
Does the Day Counter account for leap years?
Yes. It calculates the span from the actual calendar dates, so February 29 in a leap year is automatically included when it falls inside your range.
Can I use this to count down days until a future event?
Yes. Put today's date as the start and the event date as the end, and the day total tells you how many days remain. The weekday and weekend split also shows how many of those are working days versus weekends.
Is the Day Counter free and private to use?
Yes. It runs entirely in your browser with no sign-up, and no limits, and your dates never leave your device. It also keeps working offline once the page has loaded.
