Compare time zones and find the best time to meet

Instantly compare local times across cities, convert UTC, CET, EST and other time zones, and plan international meetings without timezone confusion.

One base city, a list of the others you care about, and a single draggable marker on a shared 24-hour lane. Move it once and every city reads at the same instant. Every time is worked out in your browser from its own time-zone database, so daylight-saving changes are already in the answer.

What it does

• Compare local times across many cities at once.
• Convert a specific time between any two cities, with the weekend and public-holiday consequences spelled out.
• Find the best overlap — the window where the most cities are reachable, and the next day that has one when today does not.
• Reachable hours: mark the hours you would actually take a call, on each city's own clock.
• Public holidays for every country on your list.
• Travelling: set a destination and dates, and your base switches over for them.
• Schedule: open the time you picked as a new event in Outlook or Google Calendar, with every city's local time already in the body.

Frequently asked questions — what the shaded bands mean, how daylight saving is handled, and how to turn a time into a meeting.
