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 or between the first few episodes of S4.

1) Roxy knows the Winx - meaning this would be placed during or after S4, but 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. 2) Stella said "Earth isn't ready to accept fairies", so that confirms it for me that it's an alternate reality or during early S4. 3) No one on Earth knows the Winx from their adventures on Earth during S4, meaning it's during early S4 or a different timeline entirely.

I choose to place the series after S7, but I know not everyone will choose this.
