Timezone converter

Unix timestamps in seconds or milliseconds, ISO dates with UTC offsets, local dates such as 2026-09-18 15:30, and common date phrases in the selected site language. Language coverage varies; check the detected date and time before using them. The detected text and interpretation appear before the clocks. Dates without a time use midnight.

All cards represent the same instant. Drag horizontally inside any card to update every clock together, including across midnight and daylight-saving changes. Release to snap to 15-minute intervals. Vertical swipes scroll the page. You can also type an exact date and time. Dates without an explicit offset use your selected source timezone. Skipped or repeated daylight-saving times need an explicit UTC offset. My timezone reads your browser setting; it does not request your location. Up to eight timezone choices are saved on this device.
