About this tool
Shows the current time in several cities around the world side by side, so you can see at a glance whether it's a reasonable hour to call or message someone in another timezone before you do it. Uses your browser's built-in timezone database — daylight saving is handled automatically for each city, with no manual offset to get wrong.
Each card shows how many hours ahead or behind you the city is, and turns dark between 9pm and 6am local time so you can spot who’s probably asleep. Your choice of cities is remembered in this browser. To plan a meeting for a future date instead, use the Meeting Time Across Timezones planner.
