Working Time Calendars
Throughout the examples in the Configuration chapter, we used the term Working time, let us understand that in this section.
Working time is defined in Working Time Calendars.
There is one default system wide calendar (My Start →System Admin→System Calendar) and a specific calendar per project (Project→Admin→Calendar).
All project calendars are derived from the system calendar and should only define project specific deviations.
The basic work calendar definition consists of default business hours per day of the week.

There can be multiple entries for the same day of the week to reflect historical or intentional changes.
For example: We do not work on Saturday, but starting from July 1, 2009 until December 31, 2009, we also plan to work on Saturday morning from 9:00 to 12:00.
On top of this basic weekday pattern, deviations can be defined for specific dates (day/month/year) or for the same calendar day (day/month) in every year or a specific range of years.

Examples:
January 1 is a holiday (New year) every year.
December 24 (Christmas Eve) and December 31 (New Years Eve) are not holidays, but if they default to workdays then work hours are from 9:00 –13:00, as employees leave early.
Between 1954 and 1990 June 17 was a German federal holiday known as German Unity Day in Germany. After the German east-west reunification in 1991 this was changed to October 3
August 02, 2009, although a Sunday, is an exceptional workday Midsummer Madness Sale.
