Lunar festival on Wotlk lordaeron

[Burstlolx]

Hey, does anyone know when the Lunar festival will end?
I thought it ended two days ago because every ''Lunar NPC'' disappeared, and today when i logged in they were back in the game, is it supposed to be like that or is it bugged?
However i would like to know when it ends since it doesn't say in the calendar.

Thanks :)
