How it works

Convert the target local date and time to an exact instant. Subtract the current device time and round remaining seconds upward. Days are blocks of 24 hours.

Example

A deadline at midnight in New York is a different instant from midnight in London. Select the event’s zone before starting.

Does it run after I close the page?

No. Keep the tab open. This is a live display, not a background reminder or public shared countdown. The target stays in this tab and is cleared on reload.
