Local times
How to use
Choose a source time zone, date and 24-hour time. The page starts with the current time; select Now to refresh it. Add one to five target time zones to see the same instant in each place, including local date, weekday, time, UTC offset difference from the source and day change. Search time zones or use common cities.
Daylight saving and limits
Offsets follow the selected date and named time zone, not a fixed number. If the source local time is skipped when clocks move forward, choose another time. If it occurs twice when clocks move back, choose the earlier or later occurrence by UTC offset. Results use your browser’s time zone data; future rules can change, so recheck important meetings closer to their date.
Privacy
Times, zones and results are processed in your browser. This tool does not send them to a time zone service or put them in the URL, its own storage or analytics events. Switching languages leaves the current page without carrying the input. Browser form restoration remains under browser control. JavaScript is needed to compare times; the explanation and navigation remain readable without it.
