World clock

What is a World Clock?

When your team, clients or family are spread across continents, a quick look at the current time in each location prevents calls at 3 am. This world clock shows the live time in the time zones you choose, with their UTC offsets and daylight saving time applied automatically.

How to use it

  1. Add the cities or IANA time zones you care about, such as Asia/Kolkata, Europe/London and America/Los_Angeles.
  2. Read the current local time and date in each.
  3. Use the list to judge whether it is working hours there before calling or messaging.

Example

At 15:00 in India (IST, UTC+5:30) on 27 October 2026, it is 09:30 in London (GMT, UTC+0), 05:30 in New York (EDT, UTC-4), 02:30 in San Francisco (PDT, UTC-7) and 18:30 in Singapore (UTC+8).

Things that surprise people

  • Half- and quarter-hour offsets: India is UTC+5:30, Nepal UTC+5:45, and parts of Australia UTC+9:30.
  • DST dates differ: the US changes clocks on the second Sunday in March and the first Sunday in November, Europe on the last Sundays of March and October. For a few weeks each year the gap between New York and London is 4 hours instead of 5.
  • Southern hemisphere: Australia and New Zealand observe daylight time during their summer, roughly October to April.
  • No DST: India, China, Japan and most of Africa do not change their clocks.

Tips for distributed teams

  • Schedule recurring meetings in a time window that overlaps working hours everywhere; use the meeting timezone planner to find it.
  • Write times in invitations with the time zone, or better, send calendar invites that convert automatically.
  • Rotate inconvenient meeting times fairly between regions.

Frequently Asked Questions

Does the world clock adjust for daylight saving time?

Yes. It uses the IANA time zone database, which applies each region's DST rules automatically.

Why is India's time offset by 30 minutes?

India uses a single time zone, UTC+5:30, chosen to fit the country's geographic centre.

Which countries do not use daylight saving time?

Many, including India, China, Japan, most of Africa and parts of the Americas such as most of Arizona.

How do I find a good meeting time across time zones?

Compare local times in each location and pick a slot within normal working hours for everyone, or use the meeting timezone planner.
