Time Zone Converter

Each row is a place and its time. Change the time in any row, or the date at the top, and every other place follows; Now goes back to the live time. The date at the top belongs to the place you last changed, and a row shows its weekday when its date is different.

Times come from the time zone rules built into your browser (the same IANA database your phone and computer use), so clock changes, half-hour zones like India and the 45-minute offset of Nepal are exact. A time that is skipped when clocks go forward moves on by the gap, and a time that happens twice takes the first one.

Details shows the next 24 hours in every place, with 9 to 5 shaded as working hours and the hours that suit the most places highlighted. The arrow moves a place up the list; the first place is the one shown at the top.

Your places and the time you chose are saved on this device only. Clear all goes back to just your own time zone, and Undo brings the list back.
