See one moment in every city
Pick a date and time and set the source time zone, and that exact moment appears in local time on every card, from New York to Tokyo, Istanbul to Sydney. Leave the source blank and the tool turns into a live world clock that ticks every second. Click any city card to make it your new source zone, and the whole grid recalculates around it instantly.
Copying meeting times
Each card displays the city name and its UTC offset (such as UTC+3) so you never have to work out the difference in your head. A copy button next to each time grabs that local time for pasting into an invite, email or message. Because times are read from the browser's own time-zone database, daylight-saving transitions are handled automatically for each region.
Frequently asked questions
Is daylight saving time (DST) supported?
Yes. Times are computed from the browser's Intl time-zone database, so daylight-saving transitions are applied automatically for the regions that observe them.
What happens if I leave the source time empty?
With the date-time field blank, the tool uses the current moment and runs as a live world clock that updates every second. Enter a value and it calculates from that specific instant instead.
Which cities are in the list?
It starts with UTC and includes 22 major cities and hubs, among them New York, London, Paris, Berlin, Istanbul, Moscow, Dubai, Mumbai, Singapore, Shanghai, Tokyo, Sydney and Auckland.
