About Time Zones

Time Zones shows the current time anywhere in the world, converts a time between places, and helps you choose an hour for a call or meeting. It has a page for every time zone area and country, the dates on which clocks change, and ready tables from India time to other cities.

Where the data comes from

• Time zone rules (which offset applies where, and when clocks change): the IANA Time Zone Database, release 2026f, which is in the public domain. The whole computer industry uses this database. We read it on 11 November 2026 and worked out the clock changes for 2026 and 2027 from it.
• Which country each zone belongs to, and the cities in each zone: GeoNames, licensed CC BY 4.0.

The explanations, the India time tables and the notes on abbreviations are written by us.

How the clocks work

The live clocks, the converter and the meeting planner run inside your browser. They use your device's clock and the time zone rules that come with your browser. If your device's clock is wrong, the times shown will be wrong by the same amount. Nothing you type is sent to us.

A caution

Governments sometimes change time zone rules with little warning. Dates far in the future are the rules as known today. For flights, trains, examinations and legal deadlines, always confirm the time with the organiser.
