What does this tool do?
Pick a date and a start hour in your zone, then set the UTC offset for two participants. The calculator shows each local clock time, the UTC reference and any day shift.
The Formula
Local time = UTC hour + zone offset; working hours = 09:00–17:00 localFrequently Asked Questions
What UTC offset should I enter?
Use the zone’s standard offset in hours, such as −5 for New York or 5.5 for Mumbai. Offsets do not include a daylight-saving adjustment.
Why does a participant show a different date?
A large offset can push the local time past midnight, so the participant is on the next or previous calendar day. The date shown with each time makes that clear.
