About this tool
Time Zone Converter translates a moment from one time zone to another using real zone rules, including daylight saving where it applies. Enter a date and time, pick the starting zone and the target zone, and the tool shows the same moment in the new zone. Because it uses IANA zone names rather than fixed hour offsets, it stays correct when clocks change.
Frequently asked questions
Why use IANA zone names?
Names like America/New_York carry daylight saving rules, while a plain offset like UTC-5 does not change with the seasons.
What format should the date use?
Use ISO form, for example 2024-01-15T12:00:00Z, so the moment is unambiguous.
