public Day MinusWeeks( int numberOfWeeks )
Public Function MinusWeeks ( numberOfWeeks As Integer ) As Day
|OverflowException||In the unlikely event of this method requiring a Day with a year less than 1 or greater than 9999.|
This will happily cross the borders between months and years, and it will always ensure that the returned result is a valid Day, unless it is outside the range allowed by Day (0001-01-01 to 9999-12-31 inclusive), in which case it will throw an OverflowException.
For example 2020-08-07 (a Friday) minus 2 weeks would give a result of 2020-07-24 (also a Friday).
Day is immutable, so calling this method will not change this Day.
