Privacy details

Time zone converter processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Using Time zone converter

Choose a city or IANA zone. The date matters: two places can change their clocks on different days. Meeting options find half-hour starts that keep the entire meeting inside the selected working hours in every zone. Download the selected conversion as a calendar event.

A worked example

On January 15, 2026, 09:00 in New York is 14:00 in London. On July 15, 09:00 in New York is also 14:00 in London; their offsets from UTC have both changed.

Before you use the result

Years 1900–2100. A skipped clock time is rejected; a repeated hour has two selectable occurrences. Meeting ideas use weekdays and one common workday window, with no holiday calendar. Browser time-zone rules can lag government changes.
