For work schedules that span two consecutive days, a break slot may fall across midnight. For example, if a shift starts at 8:00 PM and ends at 5:00 AM, a break could be scheduled from 11:45 PM to 12:15 AM. In such cases, msdyn_SaveCalendar will be called twice — once for the preceding day and once for the next day. However, for the next day, handling a break slot that starts at 12:00 AM (e.g., 12:00 AM to 12:15 AM) is currently not supported. Allowing break to appear at the start of the day to handle such scenario can help in scheduling overnight shifts.
