Frequently asked questions

Does the countdown keep running if I close the tab?

The display only ticks while the page is open, but your label and target date are saved locally and restored when you return.

What time zone is used?

Your own — the date you pick is interpreted in your device’s local time zone.

What happens after the date passes?

It keeps counting up and shows “already passed” so you know how long ago it was.

Is my data private?

Yes — it is stored only in your browser’s local storage.

What is Exam Countdown Timer?

An exam countdown timer shows the live time remaining — days, hours, minutes and seconds — until a date and time you choose.

Features

Live countdown

Days, hours, minutes and seconds update every second via a client-side interval timer.

Any date & time

Uses a native datetime-local input so you pick the exact date and time in your device's local time zone.

Saved on your device

The event label and target date are stored in localStorage and restored automatically — no account or server round-trip.

Counts past the deadline

If the date passes, it keeps counting up and marks the event as already passed instead of stopping at zero.

Example

Input

Event label: "Final exam"; target date/time: 2026-07-18 09:00 (device local time zone), set 7 days ahead

Output

Live tile display updating every second, e.g. "7 days 00:00:00" counting down to "0 days 00:00:01", then "— already passed" once 2026-07-18 09:00 local time is reached

Common use cases

  1. 1

Summary

Zerethon's exam countdown timer shows a live countdown of days, hours, minutes and seconds to a date and time you pick, using the browser's native Date object and a 1-second setInterval tick. Your event label and target date are saved in localStorage on your own device and restored automatically the next time you open the page. Everything runs client-side — nothing is uploaded or sent to a server.
