Contact TimeZonar support

A few details help us check it quickly:

• The city or time zone, and the time TimeZonar showed
• The time you expected, and where it came from
• The link from Copy link on the world clock, so we see exactly what you saw

Is TimeZonar free to use?

Yes. The world clock, the time picker, the map and shareable links are all free, and none of them need an account.

How accurate are TimeZonar's times?

Times come from the time zone database built into your browser, the same data your phone and computer use, so daylight saving changes and new rules are picked up automatically. A city shows a notice two weeks before its clocks change.

Can I save my cities?

Yes. Your list is remembered in this browser, and Copy link opens it on any other device. With a free account, your saved cities are kept with the account and appear on every device you log in on.

Does TimeZonar work offline?

Once the page has loaded, the clock keeps running without a connection, because the times are worked out on your device. Reloading the page needs a connection.

• Always include the time zone abbreviation in meeting invites, such as EDT or CEST.
• Use UTC as a shared reference point for teams in many countries.
• Consider local working hours, not just time zones. The working-hours chart on the world clock shows where everyone's day overlaps.
• Plan recurring meetings around daylight saving changes. The US and Europe change their clocks on different weekends.

Daylight saving time is used in around 70 countries, but not all on the same dates. TimeZonar adjusts for these changes automatically, but it is still worth double-checking important meeting times in the weeks around each change.
