Weekly quests, or weeklies, are repeatable quests that can be acquired and completed once/twice per week. First introduced with patch 3.1.2 in the combat zone Wintergrasp, they tend to have significantly better rewards than other repeatable quests.

Restrictions

The new weekly quest becomes available—at the start of the day—every Tuesday for US servers and Wednesday for EU servers, after the weekly server maintenance.

A special case were the Wintergrasp quests, which also reset every five days, in addition to the weekly reset. This is no longer the case as of patch 3.3.2.

Weekly PvP quests

The first zone to have PvP weeklies was Wintergrasp.
