World Clock & Timezone Converter
Live clocks for cities around the world — convert any time between timezones instantly
What is World Clock & Timezone Converter?
A world clock and timezone converter is a utility tool that displays the current local time for cities and timezones around the world and lets you convert any date and time from one timezone to another. It is an essential tool for anyone working across time zones — remote teams, international travellers, global businesses, and anyone scheduling calls or meetings with people in different countries.
The world clock panel shows live, updating clocks for over 30 major cities spanning all inhabited time zones. Each clock displays the current time, the UTC offset, and the city name, so you can scan the list and immediately know what time it is in New York, London, Dubai, Mumbai, Singapore, Tokyo, Sydney, and many other locations simultaneously.
The timezone converter lets you pick any date and time in a source timezone and see the equivalent time in one or more target timezones. This is particularly useful for scheduling: enter the time of your meeting in your local timezone and instantly see whether it falls within business hours for your counterparts in other cities. The converter correctly handles daylight saving time transitions, so results are always accurate regardless of the time of year.
UTC offsets and daylight saving time rules are maintained using the IANA Time Zone Database, the same source used by operating systems and browsers worldwide. All calculations run locally in your browser with no server required.
