Calculation Steps
How Meeting Time Overlap Is Calculated
The calculator scans organizer-local starts and checks every attendee's local workday.
Organizer date
Candidate times are generated on the organizer's selected calendar date. Attendees may see the same meeting on a different local date.
Workday filter
A window only qualifies when the full meeting length stays between the workday start and workday end for every selected time zone.
Daylight saving
IANA time-zone names allow the browser to apply daylight-saving offsets for the selected date rather than using fixed offsets.
Meeting Time Examples
Common global scheduling situations.
New York, London, and Copenhagen usually overlap in the New York morning for one-hour meetings.
Some pairs need wider work hours or shorter meetings because one region's morning lines up with another region's evening.
Add the second attendee zone when a third office must fit the same local workday rules.
Meeting Time Calculator FAQ
Answers about overlap windows, daylight saving time, and organizer dates.
How does the meeting time calculator choose a best time?
It scans the organizer's selected date in 30-minute increments and keeps start times where the full meeting fits inside work hours for every selected time zone.
Does this handle daylight saving time?
Yes. The calculator uses IANA time-zone names and the browser or runtime time-zone database for the selected date.
Why is there no shared meeting window?
Some distant time zones do not overlap during normal work hours. Try a shorter meeting, wider workday, or only one attendee zone.
Can I use this for more than two attendees?
Use the organizer plus two attendee time zones directly. For larger groups, pick representative regions or the strictest time zones first.
What does the selected date mean?
The date is interpreted in the organizer's time zone. Attendee dates may show the previous or next day depending on the offset.
