A moment we share
Different cities can be living inside different dates and still be inside the same instant.
This version uses a real clock input, so the conversion can stay accurate down to the minute.

How this works · sources & limits
Times use your browser’s IANA time-zone data via Intl.DateTimeFormat, including daylight-saving rules for the selected date. This version uses the selected minute too, not just the hour. Dates start with today on your device. No location permission is requested.
A local time skipped by daylight saving returns a warning. A repeated local time when clocks go back can represent two instants; this simple tool picks one. For critical scheduling during clock changes, confirm the exact UTC offset separately.
The complete answer is free. Inputs stay in this page’s memory; nothing is sent to a server or saved. Share only what you want others to see.
