Good timing is a team effort.
Working Hours Overlap
Find shared working hours across time zones. Compare custom workweeks and overnight shifts to plan remote-team collaboration and handoffs.
Calculate working hours overlap across time zones
See the continuous windows when every location is inside its working hours on your reference date. This is useful for remote-team collaboration, customer support handoffs, and finding core hours. A short overlap may still be too short for your selected meeting duration.
Set different weekends or overnight shifts for each location. Compare another date around a daylight saving change before treating a window as a permanent schedule.
A New York and London example
On January 12, 2027, a 09:00–17:00 workday in both cities overlaps from 09:00 to 12:00 in New York and 14:00 to 17:00 in London. A one-hour call at 10:00 in New York is 15:00 in London and fits both workdays. These are example working hours; holidays and existing appointments are not checked.
After finding a possible window, share a group availability poll to ask which times people can actually attend.
Dates supported: 2000–2100. Time-zone rules are checked weekly; future rules can change. All calculations use our server’s time-zone database, not the version installed in your browser.
