Days between dates calculator

Counted or not counted

By default the tool gives the difference between the two dates: from Monday to the next Monday is 7 days. If you are counting days of a stay, a leave or a rental where both the first and the last day are used, choose "Counted": Monday to Sunday then gives 7 days instead of 6. Contracts and legal deadlines often say which rule applies, so check the wording.

Working days

Working days are counted from Monday to Friday over the same span. Public holidays are not removed, because they differ by country and region: subtract the ones that fall in your period by hand. If the start date is later than the end date, the days are shown with a minus sign and the dates are put back in order.

Months are not all the same length

A difference in years, months and days counts whole years first, then whole months, then the remaining days, Months have 28 to 31 days, so when the start day does not exist in a month (31 January plus one month), the month ends on the 1st of the next month: 31 January to 1 March is exactly 1 month in a normal year. For anything that must be exact, such as interest or notice periods, use the total number of days.

Example

Two dates on one line, end date not counted.

Input

2026-01-15 2026-03-01

Output

2026-01-15 to 2026-03-01: 45 days = 0 years, 1 months, 14 days = 6 weeks 3 days; 32 working days (Mon-Fri)

How to use

1. Type a start date and an end date on each line, as YYYY-MM-DD. A single date counts up to today.
2. Choose whether the end date itself is counted.
3. Read the days, weeks, months and working days on each result line.

FAQ

How many days are there between two dates?

Subtract the earlier date from the later one. Paste both dates on one line above and the tool does it, leap years included.

Does it count the start and end day?

The start day is counted and the end day is not, unless you choose "Counted (inclusive)" in the End date option.

Are public holidays excluded from working days?

No, only Saturdays and Sundays. Holidays depend on the country, so subtract them yourself.

Can I calculate many date pairs at once?

Yes, one pair per line. A line with only one date counts from that date to today.
