What is Oktoberfest

Response:
The Oktoberfest is the world's largest Volksfest, featuring a beer festival and a travelling carnival. It is held annually in Munich, Bavaria. It is a 16- to 18-day folk festival running from mid- or late-September to around the first Sunday in October, with more than six million international and national visitors attending the event. Locally, it is called d’Wiesn, after the colloquial name for the fairgrounds, Theresienwiese. The Oktoberfest is an important part of Bavarian culture, having been held since the year 1810. Other cities across the world also hold Oktoberfest celebrations that are modeled after the original Munich event.

During the event, large quantities of Oktoberfest Beer are consumed. For example, during the 16-day festival in 2014, 7.7 million litres (2,000,000 US gal) were served, making it the year where the most beer was consumed at the Oktoberfest. Visitors also enjoy numerous attractions, such as amusement rides, sidestalls, and games. There is also a wide variety of traditional foods available.

The Munich Oktoberfest originally took place in the 16-day period leading up to the first Sunday in October. In 1994, this longstanding schedule was modified in response to German reunification. As a result, if the first Sunday in October falls on the 1st or the 2nd, then the festival would run until 3 October (German Unity Day). Thus, the festival now runs for 17 days when the first Sunday is 2 October and 18 days when it is 1 October. In 2010, the festival lasted until the first Monday in October (4 October), to mark the event's bicentennial.
