Calendar inside of the DPS

A central calendar in DPS could be very useful.
Use case: DPS web users will select a date out of this calendar during an order process e.g.. Based on the entries it should be possible for the web user to select a date or not.

To add a event in the calendar the following way could be useful:
• A source code based function.
• A manual function in a calendar view in BC
• An Import function of a file e.g. for public holiday or closing times.

Additionally, from BC side, it can be controlled if a certain day or holidays are available or not. In the case of public holidays or closing times, the BC user would simply set a date, e.g. Christmas, and the switch to non-selectable. (manual way) Then the customers sees 24.12. but cannot select it in the order process.
