Get the number of calendar weeks between 2 dates in C#
- by Phil Scholtes
For the purposes of this question, let's assume the user will be from the US and will use the standard Gregorian calendar. So, a calendar week starts on Sunday and ends on Saturday.
What I'm trying to do is determine the number of calendar weeks that exist between two dates. A perfect example of my problem exists in October 2010. Between 10/16 and 10/31 there are 4 calendar weeks.
View a picture of October 2010
October 10 - October 16
October 17 - October 23
October 24 - October 30
October 31 - November 6
I'd prefer to stay away from any hardcoded logic like:
if (Day == DayOfWeek.Saturday && LastDayOfMonth == 31) { ... }
Can anyone think of a logical way to do this?
