International Vegetarian Week
The International Vegetarian Week (IVW) consists of 7 days, October 1 to 7, where many events promoting the vegetarian lifestyle take place in several nations of the world. This annual week begins with World Vegetarian Day (October 1), which has been endorsed since 1977 by the International Vegetarian Union (IVU), which is headquartered in the U.K. Many countries and organisations have been proposing Vegetarian Weeks for several years, from Australia to the United Kingdom.
