Countdown

Count down to a date and time in a chosen timezone — useful for launches, exams, trips and events. Shared links keep the same target for everyone.

Who this is for

Anyone counting down to a fixed moment and wanting other people to see the same number: a product launch, an exam, a wedding, a departure date, or the end of an offer. Because the target is stored with its timezone and shared by link, everyone who opens it sees the correct remaining time for their own location rather than a figure that only makes sense where you are.

How to use Countdown

1. Set the target date, time and timezone carefully.
2. Start the countdown and leave the page open to watch it tick.
3. Create or open a shareable link when you want others to see the same target.
4. Update the target if plans change and reshare if needed.

Worked examples

Example 1. Personal launch countdown in your local zone.

Example 2. Shared link so a team sees one agreed instant worldwide.

Example 3. Exam morning: countdown to start time with the correct zone.

Timezones matter

The same wall-clock time in two cities can be different instants. Always set the zone that matches the event’s official schedule, not only your laptop’s local zone by accident.

Public links and admin links

Creating a countdown gives you two links and they are not interchangeable. The public link is the one to send out: it shows the countdown and nothing else, and anyone holding it can watch but not change. The admin link is your private key to that countdown — it is what lets you edit the target or remove it, and anyone who has it can do the same.

Treat the admin link the way you would treat a password. Do not post it in a group chat, a public forum or a page anyone can read; there is no separate account or login protecting the countdown, so the link itself is the whole of the security. If it does get out, the safest fix is to delete the countdown and create a fresh one rather than hoping nobody uses it.

Common mistakes

Setting the time without thinking about which timezone it belongs to. "Friday 5pm" is a different instant in Perth and in London, and choosing the wrong zone shifts the whole countdown by hours. Sharing the admin link instead of the public one is the second, and it hands the recipient the ability to change or delete your countdown. The third is assuming the page keeps counting in the background — a phone that sleeps will show a stale figure for a moment when you return to it, until it catches up.

Tips

Set the timezone to the one the event actually happens in, not the one you happen to be sitting in while creating it — a launch at 9am Sydney time stays correct for overseas viewers only if you say Sydney. Keep the admin link somewhere you will find it again, such as a bookmark or a note to yourself, because it is the only way back in to edit later. Give the countdown a clear name; recipients often see the name before they see any other context.

Accessibility notes

The remaining time is text rather than a graphic, so a screen reader can read it and you can select and copy it. It updates continuously, which means assistive software may announce changes repeatedly — the target date and event name are stated separately as static text so the important information can be read once without waiting on the ticking figure. All setup controls are standard date, time and select inputs.

Limitations (honest)

• Shared/link countdowns rely on server-stored state.
• Background tabs may update less smoothly.
• Not atomic clock infrastructure — good for human events, not lab timestamps.
• Requires JavaScript in a modern browser.

Privacy

Creating a countdown stores the event name, the target time and its timezone on the server, because that is the only way everyone opening the link can see the same figure. That is all it stores — there is no account, no email address and no record of who viewed it. Anyone with the admin link can edit or delete the countdown, so treat that link as the credential it is.
