How to use this tool

Set the Date & Time field to the moment you want to convert, then pick the zone it’s currently in under From and the zone you want to see it in under To. The Converted Time card below updates instantly, calculated using your browser’s built-in IANA time zone database — no external API call needed. Click the swap icon between the two dropdowns to flip From and To in one click. It also accounts for daylight saving time automatically, since each zone’s offset is recalculated for the date you entered.

Why the date you pick actually matters

A time zone's offset from UTC isn't always fixed year-round — zones that observe daylight saving time shift their offset by an hour for part of the year, while zones like India (UTC+5:30) don't observe it at all. Converting 3:00 PM in New York to India time lands at 1:30 AM the next day in January (New York on standard UTC−5), but 12:30 AM in July (New York on daylight-saving UTC−4) — a real one-hour difference for the exact same clock time, which is why this tool asks for a specific date rather than assuming one fixed offset per zone.

On the nights the clocks change

Two kinds of time need a rule. When clocks go forward, an hour of local time never happens: Sydney jumps from 2:00 to 3:00 on 4 October 2026, so 2:30 there is converted as 3:30 AEDT, which is 22:00 on 3 October in India. When clocks go back, an hour happens twice: New York repeats 1:00 to 2:00 on 1 November 2026, and 1:30 is taken as the first one, still on daylight time, which is 11:00 in India; the second 1:30 would be 12:00.

These are the choices JavaScript's Temporal API makes by default. Before a fix in September 2026, times in the hour after a spring change came out an hour late here, so 3:30 in New York on 8 March was treated as 4:30; if you converted such a time earlier, convert it again.

Frequently Asked Questions

Does this account for daylight saving time correctly?

Yes — the offset for each zone is recalculated based on the actual date you entered, not a fixed value, so a January conversion and a July conversion for the same zone can legitimately produce different offsets where DST applies. This matters most for scheduling across the DST transition weeks in spring and fall, when a naive fixed-offset conversion would be off by an hour.

Why do some time zones show unusual offsets like +5:30 or +13:45?

Not every time zone is a whole-hour offset from UTC — India Standard Time is UTC+5:30, and a handful of zones like Chatham Islands use quarter-hour offsets such as +12:45. These aren't errors; they reflect each region's own historical or geographic choice of standard time.
