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

I know you've found your own answer, but I'd suggest this alternative:

=Today.AddDays(1-Today.Day).AddMonths(1).AddDays(-1)

It's a little easier to read, in my opinion, and might have slightly better performance (though most likely unnoticeable)

And, of course, if you wanted to pad out that date to 23:59:59, as is often necessary, just modify slightly:

=Today.AddDays(1-Today.Day).AddMonths(1).AddSeconds(-1)
