About

Offsets include daylight saving when applicable. “Convert time” interprets the input as a wall time in Zone A, accounts for DST (including overlaps/gaps), and shows the corresponding instant in Zone B. Business days default to Mon–Fri; toggles let you include the start date or count all days. Click the map to jump to an offset band.
