You can create holiday schedules for multiple regions that follow the same work schedule but have different holidays.

1. Create a holiday schedule for each region. For example, U.S. Holidays, British Holidays, and Australian Holidays.
2. Add the work schedule as a child schedule to each region's holiday schedule.

   This method requires making <number of schedules> + 1 total schedules. If you instead make the regional holiday schedule a child schedule of the work hours schedule, you will need to create a separate work hours schedule for each region. The total number of schedules in this case is <number of schedules> x 2 schedules.
