How to Use

What is timezone conversion? Timezone conversion shows the same instant in different cities. It helps with scheduling meetings, deploying code and coordinating remote teams across timezones.

How to use it 1. Pick a date and time with the datetime input. 2. Choose the timezone to interpret it in (default is your local timezone). 3. Read the converted time in the preset cities. 4. Add one custom timezone from the dropdown if needed.

Preset cities - UTC, Beijing, Tokyo, Singapore, Sydney, Dubai and Mumbai - London, Paris, Berlin, New York, Los Angeles and San Francisco

Tips - Each card shows the UTC offset and the difference from the source timezone. - Use Now to fill in the current local time. - Conversions use the Intl API and run entirely in your browser.

Privacy All conversion is computed locally.
