How to count days between dates
Pick a start and end date to see the exact number of days between them, plus a breakdown in weeks, hours, months and years. Useful for deadlines, trips, projects and anniversaries.
March–October, for example, spans more days than you might guess because of varying month lengths.
Frequently asked questions
Does the count include both start and end dates?
The total shows the difference between the two dates. If you need to include both days (for example counting event days), add one.
How many days are in a month on average?
About 30.44 days on average. That's why the months and years figures here are approximate, while the day count is exact.
Can I calculate business days?
This tool counts calendar days, not business days. Weekends and holidays are included in the total.
Does it work for past and future dates?
Yes, any two valid dates work, in the past or the future.
