Find a meeting time that works in every time zone.

1. 1

   Pick the time and date

   Choose any time from the list, from 12:00 AM to 11:45 PM, and the date. Daylight saving is handled for that date.

2. 2

   Say which city it is in

   Type the city the time belongs to. It starts with the place your device is in.

3. 3

   Add the other cities

   Add up to seven more. Each one shows its local time and day at once. Then copy the times, share the link or download an invite.

Booking a call across three or four time zones usually means opening a few clocks and doing sums. Here you give one time, one date and one city, and every other city is worked out for you, including whether it lands on the next or the previous day. Nothing is looked up online: it uses the time zone data already built into your browser.

What it does

• Eight cities at once, found by city, country or time zone name.
• Any time of day can be chosen, in 15-minute steps, including night and early morning.
• Shows the day shift for each city, so a late call that lands tomorrow is easy to spot.
• Works for the date you pick, so daylight saving changes are right.
• Copy the times for each city, copy a link that restores the same plan, or download an .ics calendar file.
• A 24-hour bar for each city shows day and night, with the date change marked. Drag along it to move the time.
• Drag cities up or down, remove any of them, and add your own text to the copied times and the invite.
• Share as an image card with an analog clock for each city, or as a link.
• Works offline once the page has loaded.
