It is canon that Sirius was 16 years old at the time of the prank. 
That means it happened during the 6th year if Sirius' age follows 
the usual pattern.  I do think this is when James stopped tormenting 
Severus.  It would be rather stupid to continue to provoke Snape 
when he knew such a volitile scret about Lupin, regardless of 
whether or not Professor Dumbledore had forbade him to reveal it.

Bookworm:
As I posted earlier, Snape accuses Sirius of attempted murder when 
they were 16. Depending on when Sirius' birthday is, he could have 
been 16 by the end of 5th year. After all, Ron turned 16 in March 
during OoP.

We also know from PoA that it took James and Sirius "the better part 
of three years" to become animagi. (It took Peter until their fifth 
year to do it.) Assuming that they figured out Remus was a werewolf 
no later than about half-way through their first year, they could 
have become animagi by the end of their fourth year. Therefore, the 
Prank *could* have occurred during their fifth year. 

I'm not arguing that it did - I really haven't decided. We know 
*something* happened during sixth year to 'scare James straight' but 
I'm not sure it was the Prank. I believe there is much more to the 
story between James, Sirius and Severus that we haven't heard yet.
