Everyday conversion
Choose Example winter, Europe/Copenhagen as the source and America/New_York as the destination. On 15 January 2026, noon in Copenhagen is 06:00 in New York. Example today uses the current date and time in your selected source zone.
When the clock repeats an hour
In Europe/Copenhagen, 25 October 2026 at 02:30 occurs twice. First means 00:30 UTC (universal time), before the clock goes back. Second means 01:30 UTC, after it goes back. Which occurrence? appears only when this choice matters.
On mobile, choose Output to read the result. Clear removes both fields.
When the source clock goes back
- Choose an occurrence: appears only when the source clock shows this time twice.
- First: use the instant before the clocks go back.
- Second: use the instant after the clocks go back.
- Choose First if you mean the time before the clocks went back, or Second if you mean the later time. Switching changes the time shown at your destination.
