How the math works
target local time = source UTC instant + target zone offset (incl. DST)The converter interprets the date and time you enter as the wall-clock time in the source zone, resolves it to a single moment in time (UTC), then displays that moment in the target zone. Daylight saving transitions are handled automatically using your browser’s built-in IANA time zone data via the Intl API.
Common uses
- Scheduling international meetings and calls across regions.
- Planning travel arrivals and departures in local time.
- Coordinating livestreams, launches, and deadlines worldwide.
