Time Zone Converter

A time zone converter translates a moment from one zone's clock to another's: 3:00 PM in New York is 9:00 PM in Paris, 8:00 PM in London and 4:30 AM next day in Sydney — sometimes. The "sometimes" is why converters exist: daylight saving time shifts offsets seasonally, on different dates in different hemispheres, so the NY–Sydney gap alone cycles between 14, 15 and 16 hours through the year.

This converter uses the IANA zone database — the canonical source encoding every region's rules and their history — so a date-specific conversion lands on the actual offset in force that day, not a hardcoded guess.

Pick the date and time, choose the source and target zones, and read the converted local time — the date matters because DST rules apply per-day, and the tool handles them automatically.

The traps it neutralizes: hemisphere-opposite DST (US clocks spring forward in March as Australia falls back — cross-Pacific meetings shift twice a year), half-hour and quarter-hour zones (India +5:30, Nepal +5:45, central Australia +9:30), zones that skip DST entirely (Arizona, Queensland, most of Asia), and the date-line surprise where a US-evening call lands tomorrow morning in Asia.

Scheduling craft: state the zone with every proposed time ("3 PM ET" — never a bare "3 PM"), send calendar invites (they convert per-attendee automatically), and for recurring cross-hemisphere meetings, expect the local time to jump around DST transitions in March/April and September–November.
