We moved Vesnali this year to be in May due to a number of reasons, the primary one being the issues we had during Masquerade. We are looking into possibly moving it for good, because having a bigger break between the two holidays will be so much nicer on our users and on our art team! If we end up making the move a concrete thing and not just this year sort of thing, we'll update the Subetapedia to reflect that + make a news post. <3
