February is the shortest month, but it seems to have so many holidays, such as Valentine’s Day and President’s Day. And all of these.

February 3: Feed the Birds Day

Spring is just around the corner (if the groundhog on the day before this one had anything to say about it, that is), which means birds just might be popping up for the first time in months. Help them survive these last few weeks of cold by setting out some bird feeders.

February 4: Thank a Mailman Day

This holiday is a great idea. Postal workers, letter carriers, package handlers—they are downright heroic, braving the elements to deliver us our much needed mail and stuff each day. On this day, try to catch your carrier at your mailbox and let them know how much they’re appreciated.

February 5: National Weatherman’s Day

Before the Internet and smartphone weather apps made finding out what the weather was going to be like an instantaneous task, we had to rely on weather forecasters who worked for newspapers and on TV to tell us if it was going to rain or not. This day honors forecasters, past and present. Why February 5? It’s the birthday of America’s first weatherman: John Jeffries, who kept records of the weather from 1774 to 1816.

February 9: Toothache Day

We’re not sure why anyone would want to create such a holiday, but they did. It just so happens that February 9 is also, ironically enough, the day that the Hershey chocolate company was founded in 1894. It’s also the feast day of St. Apollonia, patron saint of dentists.

February 20: Northern Hemisphere Hoodie-Hoo Day

At this point, a lot of people are sick and tired of the cold winter weather and the doldrums it brings. So the proprietor of an herb company called Wellcat registered this holiday to give people some relief. We’re all supposed to celebrate by going outside at the stroke of noon, wave our hands over our heads, and yell “hoodie-hoo!” (Southern Hemisphere Hoodie-Hoo Day is on August 22—because that’s when it’s winter down there.)

February 28: Public Sleeping Day

No longer shall you or should you take a nap in the privacy of your own home (or office), away from the prying eyes of strangers. The proponents of this holiday aim to celebrate the simple joy of sleeping in public, such as a nap on a park bench or on the beach.
