About TimeZonar

Time zone coordination shouldn't be a barrier to working with people in other places. TimeZonar was made to take the confusion out of managing several time zones, for remote teams finding a meeting time, travelers planning calls home, and anyone who searched "what time is it in" and wants the answer straight away.

Open the world clock and your own time is already there, next to a few common cities. Add the cities you care about, pick a future time to see everyone's equivalent, and copy a link that opens the same comparison for someone else.

Every time on TimeZonar comes from the time zone database built into your browser, the same data your phone and computer use to set their own clocks. That database records each region's offset from UTC and every daylight saving rule, so when a city changes its clocks the change shows up on TimeZonar without anyone updating it by hand.

Because the times are worked out on your device, the clock keeps running once the page has loaded, and a city shows a notice two weeks before its clocks change, so a recurring meeting doesn't quietly move by an hour.

• The answer comes first. The current time and the comparison are on screen as soon as the page loads, without menus or tables to search through.
• Never get time wrong. Daylight saving changes, half-hour offsets and the date line are handled and clearly shown.
• No account needed. Everything works without signing up. Log in only if you want your saved cities to follow you to every device.
• Readable by everyone. The site is set in Atkinson Hyperlegible, a typeface designed for low-vision readers, and works with a keyboard and a screen reader.

TimeZonar was born from a simple frustration: missing important meetings because of time zone confusion. As remote work became normal and more teams spread across continents, the existing tools felt either too complex or too simple.

So we built the tool we wanted: a short list of your own cities, a live map that shows who is in daylight and who is asleep, and times you can trust. Open the world clock to try it.
