World Vegetarian Day is observed annually around the planet on October 1. It is a day of celebration established by the North American Vegetarian Society in 1977 and endorsed by the International Vegetarian Union in 1978, "To promote the joy, compassion and life-enhancing possibilities of vegetarianism." It brings awareness to the ethical, environmental, health, and humanitarian benefits of a vegetarian lifestyle. World Vegetarian Day initiates the month of October as Vegetarian Awareness Month, which ends with November 1, World Vegan Day, as the end of that month of celebration. Vegetarian Awareness Month has been known variously as "Reverence for Life" month, "Month of Vegetarian Food", and more. 
Several additional days of vegetarian significance are included in or on the edge of Vegetarian Awareness Month:
