Brew Day is an annual event that tips a hat and a frosty beer stein to Brell Serilis. The in-game festivities start around the beginning of March and run until (or just beyond) the real-world holiday known as St. Patrick's Day. It made its first appearance in 2006. To check the exact dates, log into the game and click the EQ2 button in the bottom right of your screen and choose Calendar from the list of options that opens. Keep in mind that the start date and end of (most) events is midnight PST, due to the location of the main office of Daybreak.
