I don't know either and I hope someone has the answer. After some googling, the only thing I found was J2S was J2 Sunday or the day Jared and Jensen do panels, meet & greets, sign autographs, and photo ops, as they tend to be scheduled together on Sundays, but that didn't seem relative in this context. But it's also the only thing I found. *shrug*
Editing to add, I also found a Hungarian Supernatural fan page that talks about J2s day as in Jared's and Jensen's day, but that is in June for them. So still no clue.
