使い方

Create a live countdown to any future date and time in a selected time zone. 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

Is the countdown stored?

No. It runs in your browser and inputs are not sent to an account.

Does the target time zone matter?

Yes. It determines the exact UTC instant being counted down to.
