How to use this tool

Choose a UTC calendar date, two cities and each person’s local working hours. This tool checks every 15-minute interval in that UTC day and lists contiguous intervals that fit both schedules. Date and local weekday are shown; weekends are excluded unless enabled. Overnight shifts are not supported. Time-zone rules come from your browser and can change, so verify an important invitation with both participants. A window near midnight UTC may fall on different local dates.
