How to find the days between two dates
- Enter a start date and an end date (either order works).
- Tick Include the end date if both days should count, e.g. for a hotel stay counted in days, or an event that runs Monday to Friday.
- Read years, months, and days, plus total days and weeks.
How the difference is calculated
Whole months are counted from the start date first; leftover days come last. When the start is on a day the end month does not have, the month ends on its last day: January 31 plus one month is February 28 (or 29).
Example: 2024-02-28 to 2024-03-01 is 2 days, because 2024 is a leap year with a February 29 in between. The same dates in 2025 are 1 day apart. With the end date included, each total grows by one day.
Frequently asked questions
Should I include the end date?
Leave it off for elapsed time (Monday to Tuesday is 1 day). Turn it on when you are counting calendar days that both belong to the period, like a Monday-to-Friday event, which is 5 days.
Why can months and days look uneven?
Months have 28 to 31 days, so "1 month" is not a fixed number of days. The total days figure is always exact.
Does it handle leap years?
Yes. Every date is converted to a day number on the Gregorian calendar, so February 29 is counted in leap years and skipped in others.
