Calculate total days, weeks, hours, weekdays and weekend days between two dates. Inputs are validated and calculations use PHP’s calendar and IANA time-zone support.

Example

Choose realistic dates or zones, calculate, then copy or bookmark the resulting URL. The query values make a calculation easy to revisit without storing it in an account.

Frequently asked questions

Are my inputs saved?

No. Calculator inputs are processed for the immediate result and are not written to a user database.

Does this account for daylight saving time?

Time-zone calculations use named IANA zones, so the rules for the selected date are applied.
