World Clock & Meeting Planner

World Clock shows the time right now in every city you work with, next to your own. Each card gives the local time to the second, the date, the zone’s short name such as BST or AEDT, how many hours ahead or behind you it is, and a sun or moon so you can see at a glance who is probably asleep.

The meeting planner below lines up a 24-hour strip for each city on the same moments. Pick a date, drag the handle or tap an hour, and every city’s local time and day appear together. Hours inside everyone’s working day are outlined in green, and the planner tells you the best window, or the closest one when there is no perfect slot. When you have a time, copy a ready-made summary such as “Thu 8 Oct 09:00 Sydney = Wed 7 Oct 23:00 London” for your invite.

It uses your browser’s own time-zone rules, so daylight-saving changes are right for the date you choose, including the odd 23- and 25-hour days. Search covers over 400 time zones plus popular cities that share one, like Mumbai or San Francisco. Nothing is sent anywhere; your list stays in this browser.

1. Type in “Add a city or zone” and pick a match. You can search by city, country, abbreviation such as PST, or an offset like +5:30.
2. Reorder cards with the up and down arrows, or remove one with ×. Switch between 24 h and 12 h at the top.
3. In “Meeting planner”, choose the date, the city whose time to plan in, your working hours and the meeting length.
4. Drag the bright handle, tap an hour, use the slider, or press “Jump to best time”.
5. Press “Copy meeting summary” and paste it into your calendar invite or message.

• Live clocks with seconds, date, zone abbreviation and the difference from your time.
• A sun or moon on each card for daytime (6 am to 6 pm) or night-time there.
• Search over 400 IANA time zones plus more than 100 popular cities, by name, country, abbreviation or UTC offset.
• Add up to 12 places, reorder them, and keep them saved on this device.
• A meeting planner with one 24-hour strip per city, aligned to the same moment, including half-hour zones such as India and Nepal.
• Working hours you set (Monday to Friday), with everyone’s overlap highlighted and a best-time suggestion.
• Correct daylight-saving handling for any date, with a note on 23- and 25-hour days.
• Meeting length from 15 minutes to 2 hours, shown on the strips and in the summary.
• One-tap copy of a summary that lists each city’s day, date and start and end time.

• Weekends count as non-working, so a Monday morning in Sydney, which is still Sunday in the Americas, will not show as an overlap.
• If your team spans more than about ten hours, there is often no shared working hour. Look at the “Closest” suggestion and take turns with the early or late slot.
• Use “Plan in the time of” to see the strips from a colleague’s point of view; the chosen moment stays the same.
• Daylight saving starts and ends on different dates around the world, so the gap between two cities can change by an hour for a few weeks in March, April, October and November. Always plan on the real date.
