Frequently asked questions
How do I convert a time between time zones?
Add the cities you need, then click the time on any card and choose a time. Every other card updates to show the same moment in its own time zone, including the date. Click Reset to Now to return to the current time.
How do I find a meeting time across time zones?
Add a card for each participant's city, then try different times on one card and watch the others change. Because the cards are sorted from west to east, it's quick to spot a time that falls within everyone's working day.
Does What Time handle daylight saving time?
Yes. What Time uses your browser's built-in IANA time zone database, so daylight saving changes and UTC offsets are applied automatically for every city.
Is What Time free? Do I need an account?
What Time is free and needs no account or sign-up. Your cities are saved in your own browser.
Can I install What Time or use it offline?
Yes. On iPhone, open it in Safari and choose Share, then Add to Home Screen. On Android or desktop Chrome, choose Install app. After the first visit it works offline. It's also available as a Chrome extension.
