Count Days Between Dates
Choose a start and an end date to see the time between them in years, months and days, as a total number of days, weeks, hours and minutes, and as business days from Monday to Friday. Tick "Include the end date (add 1 day)" when both the first and the last day should count, for example for holidays or a contract term.
The second calculator adds or subtracts days, weeks, months or years from a date and shows the resulting date with its weekday — handy for deadlines, delivery dates, notice periods and due dates. Everything is calculated in your browser.

Frequently Asked Questions
Is this date calculator free?
Yes, it is completely free and has no limits.
Should I include the end date?
By default the calculator counts the days from the start date up to the end date, like the number of nights in a hotel. If you need both days counted — for example a holiday from Monday to Friday is 5 days — tick "Include the end date (add 1 day)".
Are public holidays excluded from business days?
No. Business days are all days from Monday to Friday; public holidays differ by country and region and are not subtracted. Remove them yourself if your calculation needs it.
Is any data sent to a server?
No. All calculations are done in your browser.
