Find Days in a Month

The DaysInMonth static method returns number of days in a month. This method takes a year and a month in numbers from 1 to 12. The code snippet in Listing 6 gets number of days in Feb month of year 2002.The output is 28 days. 
 

    Private Sub GetDaysInAMonth()

        Dim days As Int16 = DateTime.DaysInMonth(2002, 2)

        Console.WriteLine(days)

    End Sub

Listing 6 
 

Using the same approach, we can find out total number of days in a year. The GetDaysInAYear method in Listing 7 takes a year and returns total number of days in that year.  
 

    Private Function GetDaysInAYear(ByVal year As Int16As Int16

        Dim days As Int16 = 0

        For i As Integer = 1 To 12

            days += DateTime.DaysInMonth(year, i)

        Next

        Return days

    End Function
