Create calendars

Question

How can I encode a calendar? I mean, how can I determine the days of the month, is it the 1st Monday, Tuesday or something else. how many days in a particular month, etc.

I mainly use PHP and C #. But I'm mostly looking for logic

Answer 1

Take a look at the type DateTimein MSDN for C #.

You can define the weekday of a given day as follows:

var date = DateTime.Parse("16.10.2010");

Console.WriteLine(date.DayOfWeek);

If you are looking for the number of days per month, try the following:

Console.WriteLine(DateTime.DaysInMonth(date.Year, date.Month));
