Spring has finally sprung, but there's more than melting snow to celebrate this month. Here are 13 quirky (but totally important) holidays to throw a party for.

1. APRIL 3: TWEED DAY

As we've already hinted: SUMMER IS COMING. Dust off your favorite tweed clothing item and get in one last wear before it's crop top and linen season.

2. APRIL 6: TARTAN DAY

... and grab your kilt while you're at it.

3. APRIL 7: INTERNATIONAL SNAILPAPERS DAY

You might not know the term "snailpapers," but it refers to newspapers (the name works both for the rolled-up shape and the relatively slow news delivery in the internet age)—and this offbeat commemoration is a good excuse to grab a piece of print.

4. APRIL 10: NATIONAL SIBLINGS DAY

Celebrate the ones who drive you mad and keep you sane—often all at the same time.

5. APRIL 11: NATIONAL LIBRARY WORKERS DAY

A day to honor the hardworking shushers and Dewey Decimal devotees who help us all on our reading journeys.

6. APRIL 12: NATIONAL LICORICE DAY

This offbeat holiday—designed to celebrate black licorice specifically—will surely be a contentious commemoration. For those of you who cringed, please enjoy your Twizzlers.

7. APRIL 12: WALK ON YOUR WILD SIDE DAY

Whatever it means for you, today's the day to get wild.

8. APRIL 18: INTERNATIONAL AMATEUR RADIO DAY

Observed every April 18, this holiday is for radio amateurs and pioneers worldwide. It also celebrates the anniversary of the International Amateur Radio Union, which was formed in Paris in 1925.

9. APRIL 23: NATIONAL ENGLISH MUFFIN DAY

It may not be as flashy as a bagel or as versatile as sliced bread, but the English muffin deserves some serious accolades (just look at it).

10. APRIL 26: HUG AN AUSTRALIAN DAY

It does not say they have to be human.

11. APRIL 26: NATIONAL PRETZEL DAY

The beer is optional.

12. APRIL 27: NATIONAL LITTLE PAMPERED DOG DAY

The pampered pooch in your life probably doesn't need more attention, but this offbeat celebration isn't just about them. It's also about recognizing the lives and needs of less fortunate dogs and fostering goodwill toward the many canines of the word.

13. APRIL 29: WORLD TAI CHI AND QIGONG DAY

A day to calm your mind and discover that the seniors in your local park are in far better shape than you.
