No heading. Tab-separated label, IANA zone, start HH:MM, end HH:MM. Up to 8 people. Windows repeat every local day, including weekends; an end before the start means overnight.

Use 1970-01-01 through 2100-12-31. The complete UTC search and every participant's local dates must stay within these years.

Options

Local working windows
Each tab-separated row supplies a person, IANA zone and allowed local time window. Those entries describe availability rather than fetched calendar events.
Date range and duration
The entered range is scanned for slots long enough for the meeting. A zone’s clock offset can change within that range.

Supported inputs and limits

Up to eight participants, seven UTC days and a 15-minute UTC start grid. Duration 15–480 minutes. Every meeting must fit an actual contiguous working window for each participant, including weekends and overnight windows. Dates 1970–2100 use installed browser timezone data, which can differ or change. No invitations or calendar access.

A matching window is a proposal

The report compares entered working windows across zones. It cannot reveal existing appointments, travel or local exceptions. Confirm availability with participants and retain the zone/date labels when sharing a proposed time.

Questions about Meeting Time Planner

Is every possible start tested?

No. Candidate starts use a 15-minute UTC grid within the chosen horizon.

How are clock changes handled?

Candidate meetings are actual instant intervals checked against each zone’s local working window, rather than assuming every local hour exists once.

Can it send the meeting invitation?

No. Copy a suitable time into your own calendar after checking participants’ availability.
