Angular Scheduler - Work Shifts

This demo uses the Scheduler component’s offset property to indicate the starting point of a day. The Scheduler’s offset can be set in multiples of 5 and can range from -1440 minutes (-24 hours) to 1440 minutes (24 hours).

For instance, if you set the offset to -120, like the First shift in this demo, the day begins at 10:00 PM on the previous day instead of 00:00. If you set the offset to 360, like the Second shift, the day begins at 6:00 AM.

You can also combine this property with startDayHour, endDayHour, and cellDuration to obtain desired display results.
