Days between dates

How the days are counted

Pick two dates and the calculator gives the number of days between them. The first day is not counted, the last one is: from Monday to Friday is four days, the same way a diary counts.

Alongside the total you get the split into weekdays and weekend days, which is what matters for a notice period, a deadline or a delivery date. The count runs in UTC, so a change of time zone or daylight saving never shifts the result by a day.

Everything is worked out in your browser. Nothing is sent anywhere, so the dates stay with you.

Frequently asked questions

Does it count the first day?

No. The count starts the day after the first date and includes the last one. That matches how deadlines are usually written.

Does it know public holidays?

No. Public holidays differ from country to country, so counting them would mislead more than help. The weekday figure covers Monday to Friday; subtract the holidays of your own country yourself.

Can the second date be earlier than the first?

Yes. The order does not matter, the calculator always returns a positive number of days.

How are weeks worked out?

The hint under the total splits the days into whole weeks and the remainder, which is handier for longer ranges than a single large number.
