Darkmoon Faire - First of every month lasting a week
A gathering of the exotic from around the world and beyond, Silas Darkmoon has brought together the Darkmoon Faire as a celebration of the wondrous and mysterious found in Azeroth. While the Faire spends most of its time in parts unknown, they do stop from time to time in Mulgore and Elwynn forest. When the faire is on its way, barkers will stop by Orgrimmar and Ironforge to announce its arrival.
The Darkmoon Faire begins set up on the first Friday of each month, and continues for 3 days. On the early morning of Monday (4am server time), the Faire will begin.

Features:

Many exotic vendors travel with Silas Darkmoon, offering adventurers hard-to-find items from the far corners of Azeroth.
Players can earn tickets by gathering trade goods for Darkmoon Faire's vendors, which can then be turned in for items and special equipment.
Strange sets of cards have been broken up and scattered across Azeroth. Players who are lucky enough to collect a complete set of these cards can turn them in at the faire to receive epic items.
Cheap booze.
