How to use this calculator
Enter a date and time in the source zone to see the same moment in the destination zone. Conversion happens in your browser.
Daylight-saving rules are applied for the selected date. Repeated times default to the earlier occurrence; you can choose the later one. Rules come from your browser’s timezone data; its update date is not available. Verify critical meeting or travel times. Timezone lists run from east to west by the displayed UTC offset, from the most positive to the most negative. Places sharing an offset are alphabetical by their displayed city name. The header and My Age lists use current offsets; Countdown uses the target instant and timezone conversion uses the entered instant. Daylight-saving changes can change the order.
Worked example
July 10, 2026 at 12:00 UTC is July 10 at 08:00 in America/Toronto. Changing the destination preserves the same moment. During a clock change, a local time can be missing or repeated.
