Comments

The FirstDate property defines the first valid date.

The edit control contents are not considered valid (see Contents.Valid) until the date is within the specified range. The user cannot select a date outside of the date range defined using FirstDate and Calendar.LastDate using the popup calendar.

If the date defined using LastDate is prior to the date defined using FirstDate, the range Calendar.LastDate to FirstDate is considered the valid range.
