What is the first/last week of a month? [closed]

Answer 1

If you are building a library, you should allow the user to choose how they want to handle it either by having methods that return the first/last full/partial week of the month or by passing an argument that indicates whether you want the full/partial week. Clearly document whichever is the default if you provide methods that don't require the specification.

public Week GetFirstFullWeekOfMonth( DateTime forDate ) { }

public Week GetFirstPartialWeekOfMonth( DateTime forDate ) { }

Or

public Week GetFirstWeekOfMonth( DateTime forDate, bool includePartial ) {}
