Days and Shifts

A day can consist of one or more shifts. A shift is a part of the day and can be 24 hours maximum.

Example 1: A day can consist of a 'morning shift' starting at 06:00 and ending at 14:00 in the afternoon, and a 'late shift' starting at 14:00 and ending at 22:00 in the evening.

Example 2: A day '2x8' can consist of 3 shifts, 'morning shift', 'late shift' and 'night shift' of which only the morning and late shift are productive.

The days are used to prepare calendars.
