User blog comment:7-45 Fire/Should World of Winx information count?/@comment-31892545-20170619010407

I think it's pretty much safe to call this an alternate reality, between the first few episodes of S4, or during/after S4 for a few reasons. The reasons below are considering series timeline placement, but WOW can be considered an alternate reality entirely considering all of these points.

During/After Mid S4 -

1) Roxy knows the Winx comfortably (meaning, they're not strangers anymore) - meaning this would be placed during or after S4. Roxy seemed comfortable with her magic in WOW, and mentioned having wings, so we'd have to place WOW at least after S4E13.

Early S4 -

1) No one on Earth knows the Winx from their adventures on Earth during S4, meaning it's during early S4.

2) The humans don't know about magic in WOW - the Winx try to keep their magic hidden just like in the first few episodes in S4.

3) Stella said "Earth isn't ready to accept fairies", meaning we could place WOW during early S4.

Note: In WOW, they made a career from their band, which they don't deem the "Winx Club Band" or the "Winx 6" like in the series, and it looks to me that WOW S2 takes place after "a few years" taking what Tecna said in WOW S2E1 into consideration.

Unless proven otherwise, I choose to place the series after S7, ignoring all the points I provided, but I know not everyone will choose this. But, should WOW "count"? Absolutely. Even if we don't know where to place it in the standard timeline, we should consider the events canon somewhere, in my opinion. :)
