Scheduling across time zones

The overlap is calculated from today's offsets. If the call is weeks away and one of the two countries changes its clocks before then, the window can shift by an hour — worth checking again close to the date.

Where the overlap is narrow, keep the first and last 30 minutes free. Those edges are lunch breaks and commutes for someone.
