About the Time Zone Converter
Time zone rules come from the IANA time zone database built into your browser, which records every country's daylight saving dates. Converting for a specific date matters: New York is 5 hours behind London most of the year, but only 4 for a few weeks in March and October/November when their clocks change on different dates.
The formula
Local time = UTC + zone offset (including daylight saving on that date)
Worked example
Example: 18:30 in New York = Wed 1 Jul, 22:30
- Inputs: Date: 1 July 2026; Time (24-hour): 18:30; From: America/New York; To: UTC.
- Formula: Local time = UTC + zone offset (including daylight saving on that date)
- Result: 18:30 in New York = Wed 1 Jul, 22:30
Questions people ask
Why does India have a half-hour offset?
India uses a single zone, UTC+5:30, the mean time near the centre of the country.
What happens on the night the clocks go forward?
An hour is skipped, so a time in that hour doesn't exist; the result shows the equivalent valid time.
