Current time in cities around the world, with each local UTC offset, the difference from your own zone, and whether it is day or night there right now.
What this tool handles
Your zone comes first
The clock detects your system time zone and shows it as the reference, so every other city is labelled with the difference from you.
Day or night at a glance
Each city shows a sun or moon based on the real solar position for its coordinates — handy before scheduling a call.
Your list is remembered
Cities are saved in your browser only. Search matches city names, countries and IANA zone ids, and can be filtered by continent.
Frequently asked questions
Which cities can I add?
Around 130 cities covering every continent, including all major capitals and financial centres. Search accepts the city name, the country, or the IANA zone id such as Asia/Tokyo.
Why does a city show "Tomorrow"?
Because the calendar date there is already ahead of yours. Time zones span more than 24 hours in total, so two cities can legitimately be on different dates at the same instant.
Are the offsets adjusted for daylight saving?
Yes. Offsets come from the IANA time zone database in your browser and are evaluated for the current instant, so a city that is on summer time shows its summer offset.
Is my city list synced anywhere?
No. It is stored in your browser local storage and never leaves your device, which also means it does not follow you to another browser.
