Hoodie Hoo Day is observed on February 20, 2017. One month before the first day of spring in the Northern hemisphere Hoodie Hoo Day takes place. This unofficial holiday was created by Ruth and Thomas Roy. At noon people should go outside on Hoodie Hoo Day and scream a cheerful "Hoodie Hoo!" at each other.
Anything that announces the coming of springtime is appreciated on Hoodie Hoo Day. For example people are supposed to already order seeds or start their housecleaning for spring. Preparing for garden work by doing some sports also is a good way to spend your time on Hoodie Hoo Day.
