when we use base calendar while conmposing the working times in the calendar (basic>calendar)
The control for a particular day of calendar can be 1)Open, 2)Closed or 3)Base calendar
what is meaning of this three controls?
Erm, Open means you are open, Closed means you are closed.
In your calendar screen you have a reference to a base calendar, which is a calendar itself, the system is saying we are open or closed depending upon the setting in the base calendar rather than this calendar.
