How it works
Timezone Converter maps date-time values across regions to support global releases, support operations, and incident timelines. It reduces scheduling mistakes between teams in different time zones. Prefer IANA zone names for accurate DST handling.

FAQ
Should I use offsets or named timezones?
Use named timezones (like America/New_York) because offsets alone cannot model daylight saving transitions.
How do I avoid timezone bugs in APIs?
Store timestamps in UTC and convert to user locale only at display time.
