Convert a meeting time across time zones

Pick a source IANA time zone such as America/New_York, enter a date and 24-hour wall-clock time, and add the zones you want to compare. Each result shows the local date and time, its UTC offset (for example UTC+01:00), and the shared UTC instant the inputs resolve to. Daylight saving transitions are handled automatically, so an evening in Los Angeles correctly lands on the next calendar day in Tokyo.
