Compare live local times across cities worldwide, or pick a specific date and time to see what it is everywhere else. Powered by real IANA timezone data, so daylight saving time is always handled correctly.
Choose live "now," or convert a specific moment.
Choose up to 6 cities from the list below.
This free tool runs entirely in your browser using JavaScript's built-in time APIs, so nothing you enter is uploaded or stored. Pick a time mode, choose your cities, and compare.
Use the live "now" clock, or set a specific date and time to convert.
Select up to 6 cities from the curated list to compare side by side.
Each card shows the local time, date, and whether it falls on a different day.
Timezone offsets are not fixed numbers you can hardcode — many regions observe daylight saving time, shifting their offset from UTC twice a year on different dates. This tool uses each city's real IANA timezone identifier (like America/New_York or Asia/Tokyo) together with your browser's timezone database, so conversions stay accurate year-round.
A fixed offset like "UTC-5" is wrong for half the year in places that observe daylight saving time.
A standardized identifier such as "Europe/London" that encodes a region's full history of offset and DST rules.
Each card shows whether that city is a day ahead or behind your local calendar date.
Switch to "Set a specific date & time," enter the moment you want to convert in your own local time, and every selected city updates instantly to show the equivalent local time and date.
Yes. Times are calculated using each city's real IANA timezone identifier and your browser's built-in timezone database, so daylight saving changes are applied automatically, unlike tools that use fixed UTC offsets.
You can select up to 6 cities at a time from the curated list. Uncheck a city to free up a slot for another one.
Yes. It is free to use, and all time conversions happen locally in your browser using JavaScript's built-in time APIs rather than being uploaded or stored by the tool.
