The aim of this report is to create a matrix, showing how many actors there are for each season and month of birth:

The "season" is fairly loosely defined. This shows that more actors are born in the winter (hardly surprising, since by our definition Winter lasts twice as long as Summer).

To do this, first create a report called Thespian Theasons, to include a dataset based on the tblActor table of actors.

Now add two calculated fields to your dataset as follows:

The two new fields we'll create, as explained below.

The two new fields should use expressions as follows:

Field	Expression
BirthMonth	Use the Month function to find the month corresponding to the actor's date of birth.
BirthSeason	Use an IIF function to work out the season in which this month occurred: if the month is after 4 and before 9, we'll call it Summer; otherwise, we'll say this is Winter (at the time of writing this exercise, in early July, it's hard to distinguish between the two).
