How it is calculated
The time you choose is read in the origin time zone and converted to UTC, then shown in the destination time zone. Daylight saving rules come from the IANA database built into your browser.
Assumptions and limitations
- Governments can change their time rules; your browser updates with those changes.
- Some regions of the same country use different zones (for example, in Mexico and the U.S.).

Frequently asked questions
How do I calculate the time difference between two cities?
Compare their UTC offsets on the same date. New York is UTC−5 in winter and UTC−4 in summer, while Mexico City has stayed at UTC−6 all year since Mexico ended daylight saving time in most of the country in 2022, so the difference changes during the year.
Does the converter account for daylight saving time?
Yes. It uses the time zone database built into your browser (IANA), which includes daylight saving rules for each place on the date you choose.
Why does the difference change in March and November?
Because the United States and Canada change their clocks on different dates from Europe, and many Latin American countries do not change them at all.
