Plan one event across multiple time zones

Start with the venue or host team’s local date and named timezone. Add the event duration, then choose the participant locations that need to appear in the briefing. TimedFlow calculates the local start and end in each zone.

Use named zones instead of fixed offsets

“UTC−5” is not always New York time because daylight-saving rules change during the year. IANA names such as America/New_York preserve the correct regional rules for the event date.

Move the global schedule into the timer room

Opening the plan in TimedFlow carries the selected zones and source start time into the interactive event demo. The timer remains the shared operational clock while each participant sees a familiar local reference.

Frequently asked questions

Does the timezone planner handle daylight saving time?

Yes. It converts the selected local event date through the browser’s IANA timezone data, so the offset is based on that date rather than today’s offset.

Which timezone should define the event?

Use the timezone of the venue or the team that controls the event. Publish that source timezone alongside converted times so participants have a clear reference if their calendar settings differ.

How should I share a global event time?

Include the date, local time, named timezone, and a few major participant zones. A calendar invitation should still be the final source because it follows each attendee’s device timezone.

Take the plan into the live room
