Convert any date and time between time zones, with your zone detected automatically and your choices remembered.
Yes — conversions use each time zone's real current offset (including daylight saving where it applies), calculated fresh for the date and time you're converting, not a fixed offset.
Yes — your base zone and the zones you've added are saved in your browser's local storage, so they're there the next time you visit. Nothing is sent to a server.
Common abbreviations map to their most widely searched-for meaning (e.g. EST is US Eastern Time, IST is India Standard Time) — the same convention used by other time zone converters. If you need a specific city instead, add it directly from the zone list.
