There is an event called Darkmoon Faire that appears in the game once a month, starting at 00:01 on the Sunday before the 1st Monday of each month. During the event you can complete quests for each professions.
The profession quests can only be completed once during each Darkmoon Faire and will grant 5 skill points (means you can complete them again once at the next faire). Some of the quest requires additional items, but all of those items can be bought from vendors, don't buy them from the Auction House.
The location of the Faire is on Darkmoon Island. The portals to the Island can be accessed in the following locations:
- Eastern Kingdoms, on the south side of Goldshire in Elwynn Forest
- Kalimdor, in Mulgore at the base of Thunder Bluff
