"The first Equestria Girls isn't concidered canon either" – yes and no.

In the show itself there hasn't been any mention of the Equestria Girls adventure. Yes, there was Flash Sentry, but he's just an ordinary guardspony that we simply first met in the movie. Nothing says with absolute certainty that EG is canon.

On the other hand, nothing says it isn't. You can easily place those events between season 3 and 4. I know no in-show evidence that would contradict EG.

In the end, it's only up to your personal preference what you consider canon and what you don't. It's really the same with IDW comics and those official books. Well, one comic arc kinda tells you to consider what happened in EG as canon, but I find it believable, that somebody would consider a movie from the same crew as the show as canon sooner, than third party comics.

As for the original question – don't worry about it for now, just wait and see. Maybe indeed 30 moons have passed… along with some seasons, therefore making it non-chronological? Maybe it's human Twilight from that world (imagine the confusion it would cause to the characters)? Or maybe the portal had opened early (either by itself or through someone's action – voluntary or not)? Or maybe, since moon is artificially controlled, the cycles take less than a month? Or maybe something else I can't think of right now? The possibilities are rich.
