Time Zone Converter

This free time zone converter shows what a chosen date and time is across any number of cities and zones at once — ideal for scheduling calls and meetings across the world. It uses your browser's built-in IANA time zone database (every zone your system knows, searchable as you type), so daylight saving is handled automatically for each zone. Pick a source time, add the zones you care about, and read the results instantly.

Every row shows the local date and time, the zone's GMT offset and abbreviation, and how far ahead or behind it is from your source zone. Rows sort automatically by offset, and a day/night marker (plus optional working-hours highlighting for 9am–5pm) makes it easy to spot who's awake and who's at their desk. Switch between 12- and 24-hour clocks, toggle seconds, and flip on Live to watch the clocks tick in real time.

Copy every converted time as plain text for pasting into an email or chat, or copy a shareable link that reproduces the exact date, source zone, and list of zones — your selection is also remembered in this browser.
