Timezone overlap
Working with someone across the world? Pick both timezones to see which working hours (9am–5pm local) you share. Great for planning remote calls and async handoffs.
Select two timezones to see your shared working window and a full 24-hour overlap table.
How it works
How the timezone overlap calculator works
Pick your timezone
Choose your own UTC offset — the number of hours your local time sits ahead of or behind UTC.
Pick your teammate timezone
Choose the UTC offset for the person or team you work with across the world.
See the shared window
Read the working hours you both share, shown in your local time, their local time, and UTC.
Plan calls and handoffs
Use the overlap to book live calls, and hand work off asynchronously for the hours you do not share.
Timezone overlap FAQ
Many distributed teams aim for about 4 hours of shared working time. That is enough for a daily check-in, a few live calls, and quick back-and-forth, while leaving the rest of the day for focused async work. Less overlap can work, but it leans harder on written handoffs.
Async work means people contribute on their own schedule instead of at the same moment. You leave clear written updates, decisions, and questions, and a teammate picks them up when their day starts. It is how teams stay productive when their working hours barely overlap.
Find the shared window first, then book inside it so nobody joins at midnight. Rotate the meeting time if the overlap sits early for one side and late for the other, keep a written summary for anyone who could not attend, and confirm the time in each persons local zone.
Look for listings that name a required overlap, such as 4 hours with a US or European team, rather than a fixed office location. Browse remote jobs on WFHJ and check each role for its timezone expectations before you apply.
