Name the event, set its date and start time, and pick the timezone it is announced in - the live countdown, your local time, and the world table update as you type. Copy link puts the whole event into one shareable URL, so the person you send it to sees the same moment in their own timezone. The page opens with a sample event already ticking; replace its three fields with your own.
Event Time Countdown - What Time Is It For Me
Event Time Countdown pins one event - a name, a date and start time, and the timezone it happens in - and turns it into a live countdown you can share. The page shows the exact moment in your own timezone, ticks down every second, and packs the whole event into a single copyable link. No account, no upload, nothing installed.
Type an event once, share it everywhere
Give the event a short name, pick its date and start time, and choose the timezone the time was announced in. The timezone box is a type-to-search field backed by the browser's own timezone database, so every IANA zone - from America/New_York to Asia/Ho_Chi_Minh - is available without scrolling a giant dropdown. As you type, Event Time Countdown writes the event into the page address as a compact query string. Press Copy link and hand that URL to anyone: when they open it, the same event renders immediately, converted into their own timezone. The link is the invitation - there is no event database behind it and nothing to expire.
Built for the what-time-is-it-for-me question
Launches, live streams, game releases, webinars, and kickoffs are usually announced in one zone: 8 PM Eastern, 19:00 UTC, midnight in Tokyo. Everyone elsewhere is left doing offset arithmetic, and hand-counted offsets go wrong precisely when daylight saving shifts one side of the conversion. Event Time Countdown answers the question directly: a bold line states the event moment in your timezone, detected automatically from the browser, and a table underneath lays out the same instant in the event's own zone plus New York, Los Angeles, London, Paris, Tokyo, and Sydney, so a distributed team or audience can read their wall-clock time at a glance.
Daylight saving handled by the browser's timezone database
The tool resolves the wall-clock reading you enter into one exact instant using the timezone data built into the browser, settling the offset in two passes so entries that land near a daylight-saving switch resolve to the correct hour. From then on the countdown is plain arithmetic on that instant. A countdown that runs across a DST changeover never jumps by an hour, and a link opened in a zone with different DST rules still shows the same true moment.
Runs entirely in this tab
Everything happens in the page: no upload, no server call, no stored copy of your event anywhere except the link itself. Keep the tab open to watch the tick - the countdown does not run in the background and does not send notifications. Once the moment arrives, the display flips from counting down to counting up, showing how long ago the event started, which makes the same shared link useful during and after the event.
Pick the right time tool
Event Time Countdown is built for one dated event shared across timezones. To convert an arbitrary wall-clock reading between two zones without a countdown, use the time zone converter. For a plain duration timer counting minutes and seconds, the countdown timer is the simpler fit. To count down to public holidays by country, open the holiday countdown.
Frequently Asked Questions
How do I share a countdown with someone in another timezone?
Set the event name, date, time, and timezone, then press Copy link. The URL carries the whole event, and anyone who opens it sees the same moment converted into their own timezone, with the countdown already ticking. Nothing is stored on a server - the link itself holds the event.
What happens when the event time arrives?
The display flips from "starts in" to "started" and begins counting up, showing how long ago the moment passed. The same shared link keeps working during and after the event.
Does daylight saving time break the countdown?
No. The date and time you enter are resolved into one exact instant using the browser's built-in timezone database, with the offset settled across daylight-saving transitions. The countdown is then computed from that instant, so it never jumps by an hour at a DST changeover.
Which timezones can I pick?
Every IANA timezone the browser knows - typically more than 400, searchable by typing part of the name, such as a city. On very old browsers that cannot list zones, a built-in set of 20 major zones is offered instead.
Does the countdown keep running if I close the tab?
No. It runs only while the page is open, and it does not send notifications or background alarms. Because the event is stored in the link as an exact instant, reopening the link later resumes the countdown at the true remaining time.
