Earth Day is April 22. Earth Day is most often observed by the media, hundreds of local groups and noted on calendars on April 22. Many people also observe Earth Week and Earth Month. Since most events and festivals need to take place on a weekend, Earth Day is observed on the weekends before and after April 22. Others also observe it on March 21, the Vernal Equinox or on World Environment Day, June 6. For those of us who are really committed to the evironmental well being of our planet, Earth Day Is Every Day.
