The ClearNonworkingDates method removes all non-working dates that were previously added using AddNonworkingDate. It does not affect days defined by the NonworkingDays property (such as weekly non-working days like Saturday or Sunday). The RemoveNonworkingDate method removes a specific non-working date that was added with AddNonworkingDate. The NonworkingDays property retrieves or sets the weekly non-working days using a bitmask value, where each bit corresponds to a specific weekday.

You can control how non-working days appear using:

• NonworkingDaysPattern,  sets the fill pattern for non-working days
• NonworkingDaysColor, sets the fill color for non-working days
