Timezone Converter

The converter uses your browser's Intl API with IANA timezone data, which correctly handles Daylight Saving Time transitions for every timezone. The results account for DST automatically based on the date you select.

All IANA timezones supported by your browser are available in the dropdown - typically 400+ timezones covering every region in the world. Your local timezone is selected by default.

While most timezones differ by full hours from UTC, several use 30 or 45-minute offsets. Examples: India (UTC+5:30), Nepal (UTC+5:45), Iran (UTC+3:30), Newfoundland (UTC-3:30). These fractional offsets are historical — often set to match solar noon for the region's geographical center rather than aligning with arbitrary hourly boundaries.

Unix time (epoch) counts seconds since January 1, 1970, 00:00:00 UTC — the Unix epoch. It ignores leap seconds, treating each day as exactly 86400 seconds. This makes it simple for calculations but means it doesn't perfectly track astronomical time. The IANA timezone database handles UTC-to-local conversions.

Use this converter to find the equivalent time in each participant's timezone. Convert your proposed meeting time to each timezone and check it falls within work hours. The live city clocks help verify current offsets. For recurring meetings, account for DST changes — a fixed UTC time may shift local display times seasonally.

Yes! The 14 major city clocks update every second, showing the current time in that city based on its timezone. Use this for quick reference when scheduling across regions.
