Frequently asked questions

What is a time zone and a UTC offset?

A time zone is a region that keeps the same standard time, and its UTC offset is how far ahead or behind Coordinated Universal Time (UTC) it is — for example India is UTC+05:30 and New York is UTC-05:00 (or UTC-04:00 in summer). This time zones list shows the current offset for every IANA zone.

What is the current time in a specific time zone?

Type a city or region in the search box and read the current time column — it updates live every second. For example, search “Tokyo” or “Asia/Tokyo” to see Japan's current time, or “London” for the UK.

Does this time zone tool handle daylight saving time (DST)?

Yes. Offsets and times come from your browser's built-in time zone database, so daylight saving time is applied automatically and the current time and UTC offset shown are always correct for today's date.

What is an IANA time zone name?

IANA time zone names are the standard identifiers like Asia/Kolkata, America/New_York or Europe/London, used by operating systems and programming languages. Each row shows the IANA name under the city so you can copy the exact value into your code.

How do I convert between two time zones?

Search for both zones and compare their current time and UTC offsets directly in the table — the difference between the offsets is the time difference. Your own detected time zone is also shown so you can compare any zone to your local time.

Is this all time zones tool free and private?

Yes — it is completely free with no sign-up, and everything runs in your browser using the built-in Intl engine. No API, no keys and nothing is sent to a server, so the time zone list works even offline once loaded.

Can I copy a time zone name or UTC offset?

Yes. Tap the IANA time zone name or the UTC offset in any row to copy it to your clipboard, ready to paste into a calendar event, form or code.

What is the UTC offset for IST, EST or GMT?

India Standard Time (IST) is UTC+05:30, Eastern Time (EST) is UTC−05:00 (UTC−04:00 in summer as EDT), and GMT is UTC+00:00. Search the city or region in the list to see the live current offset, which already accounts for daylight saving.

How do I find the time difference between two cities?

Search for both cities and compare their UTC offsets — the gap between the two offsets is the time difference. For example, India (UTC+05:30) is 10.5 hours ahead of New York (UTC−05:00). Your own zone is shown too for quick comparison.
