Find a meeting time across time zones
Scheduling a meeting across time zones means finding a slot that is reasonable for everyone, which is hard to do in your head. This planner finds overlapping meeting times for participants in different time zones using their UTC offsets.
Why cross-timezone scheduling is hard
A meeting time that is mid-morning for one participant might be the middle of the night for another, and mentally juggling several offsets to find a slot that works for all is error-prone. The planner takes each participant’s timezone and shows the overlapping windows where the time is reasonable for everyone, so you can pick a slot without the mental arithmetic or the awkward mistake of proposing a time that is 3am for someone. This is essential for any team or group spread across the world.
