I have a a couple of very simple parameters setup (`cos simple is all I know how to do) which return a start date and an end date.

How can I use the dates entered to return values which are the same dates from the previous year?

So I`d want to be able to enter 01/01/17 and 31/05/17 to get this year`s data but I would also want to see the data from the previous year without entering 2 new dates.


and invoice.taxdate >= ?
and invoice.taxdate <= ?
