How do I get the last day on the month using SQL Reporting Services

Question

In SQL Server Reporting Services, how would I calculate the last day of the current month?

Answer 1

There is an even easier way as in the marked answer:

=DateSerial(Year(Now()), Month(Now())+1, 0)

Since DateSerial() accepts integers as parameters one does not have to use AddMonths() and AddDays(). As in the example an instant calculation inside DateSerial() is possible.

Furthermore day 1 is the first day of the month while the first day minus one day is the last day of the month before (1-1=0). So the example will return the date of the last day of the current month.
