Just think of any random thing...a day to celebrate it probably exists. It s pretty amazing how many things have a National Day attached to them. National Name Your Car Day is a thing. Kiss a Ginger Day is in January. August brings us National Underwear Day. And the list goes on and on, as you can see with this website dedicated to all the different occasions.
Oh..and today (1/15) happens to be National Hat Day. The National Day Calendar website says Wear your favorite hat on National Hat Day. Celebrate an era or an occupation. Learn the history of a particular hat or try making a paper hat. Be sure to wear a hat and use #NationalHatDay to post on social media.
