What the World Clock & Meeting Planner does

Working across time zones means constantly asking “what time is it there?” and “when can we all meet?”. Add the cities you care about and this page shows each one's current time, date, UTC offset and whether daylight saving time is in force, with a sun or moon to show who is awake. Switch to the meeting planner to lay out a full day for every city, shaded for working hours, so the best overlap is obvious. Offsets come from your browser's time-zone database, so they follow the real rules for any date.

How to compare time zones and plan a meeting

  1. On World clocks, search for a city or country, or type an IANA zone name such as Asia/Kolkata, and add it. Remove a city with the ✕ on its card.
  2. Use Display to switch between 12-hour and 24-hour time and to show seconds.
  3. Open Meeting planner, choose the date, the time zone whose hours form the columns, and the working day for your team.
  4. Read the grid: green cells are working hours, dark cells are night, and a bright column means everyone is available. The summary names the best hours.
  5. Select a column to see the time in every city, and use Copy this schedule to share it.

The World Clock & Meeting Planner runs entirely in your browser — nothing you enter is uploaded, stored, or logged.

When to use it

Scheduling with a remote team

Find the hours when engineers in Bengaluru, London and New York are all at work, instead of trading messages about it.

Calling family or clients abroad

Check that it is not the middle of the night before you ring, and see whether daylight saving has changed the gap.

Planning travel and events

Convert a webinar or match start time to several zones for the day, including around clock changes.

Good to know

  • Daylight saving starts and ends on different dates in different countries, so the gap between two cities can change for a few weeks.
  • India, China and Japan do not observe daylight saving time.
  • Always include the time zone (or UTC) when you send a meeting time.
  • A day shift marker (+ or −) in the planner shows a cell is on the next or previous day.
  • Use UTC as a neutral reference when a meeting involves more than three zones.

Frequently asked questions

Does it handle daylight saving time?

Yes. Offsets come from your browser's time-zone database and follow the actual rules for the date you pick, including the different dates countries switch. The planner shows the correct local time even across a change.

What time zone does it use as my own?

Your device's time zone, read from the browser. It is shown as the first clock, and the planner uses it as the base by default.

Why are some cities listed together, like Delhi / Mumbai?

Cities that share a time zone show one clock. All of India uses a single zone, UTC+5:30, so one entry covers every Indian city.

What is an IANA time zone name?

The standard identifier for a region's clock rules, such as Europe/London or America/New_York. It is more precise than an abbreviation like EST, because it includes the region's daylight-saving history.

Why are some zone abbreviations shown as GMT+5:30?

Your browser shows a short name only where one is widely used. For others, such as India, it shows the offset from UTC.

How accurate is the time?

It uses your device's clock. If your computer's clock is wrong, every city will be off by the same amount.
