How to use time zone converter
Choose a date, clock time, source zone, and destination zone. Using the date makes seasonal offsets explicit. Search by city or pick a fixed abbreviation such as PST.
Worked example
09:00 in New York on January 15, 2026 is 14:00 in London on the same date.
What the result means
PST is fixed UTC−08:00; Los Angeles uses seasonal Pacific Time. Missing times are rejected, and repeated times require a choice.
