> The Prank takes place in the sixth year, we know that for a fact.

Dana:
Could you provide canon for your so called fact? Because there is none. 
Lupin never mentioned in what year the prank took place and Sirius 
never said anything more about it then "served him right". Just because 
sources *outside* of canon say it is assumed to have taken place in the 
6th year, does not make it fact. 

And if you read the conversation between Lily and Snape about James 
saving Snape then you see that Lily and Snape were still friends at 
that point in time, while after Lily talked to Snape after the SWM, 
they are parting their ways. 

The prank took place before SWM as canon stands now.
