Time Zone Meeting Poll

How this works

Pick a date, time, and the time zone that time is in, then add everyone else's time zones to compare against. Each row shows the equivalent local time, its UTC offset, and a same/different-day flag when the conversion crosses midnight. Behind the scenes, this also scans ten days on either side of your chosen date in every zone — if any of them are about to spring forward or fall back within that window, you'll see a warning so you know this exact offset is temporary.

FAQ

Why does this warn about daylight saving?

Because not every place observes it, and the ones that do don't all switch on the same date. The US and the EU, for example, both use daylight saving — but they change on different Sundays each spring and fall. For a week or two around those transitions, the gap between two time zones can be an hour off from what you'd expect, which is a classic cause of a remote team showing up to a recurring meeting at the wrong time.

How accurate are the calculated times?

They're read from your device's IANA time zone database (via the browser's Intl API), the same source operating systems and most software use, and it's updated whenever a country changes its DST rules. As long as your device is reasonably up to date, the conversion is accurate.

What if my time zone isn't in the list?

The list covers major zones by UTC offset — most places share their offset and DST behavior with one of the cities listed, so pick the closest one. If you know your IANA time zone ID (e.g. Europe/Warsaw), the underlying math handles any valid zone; this list is just a curated shortlist for convenience.

Why do some zones show +1 day or -1 day?

Because the same instant in time falls on different calendar dates depending on where you are — most noticeably across the International Date Line. If a meeting at 9pm on the 15th in your zone lands at 6am on the 16th somewhere else, that's not a bug — it's exactly why this tool exists.
