Though some parts of the country are still clearing out from last week’s snowstorms, spring is officially here—a little bit early, but not a moment too soon. And if the idea of soon-to-be-blooming flowers isn’t enough to get you excited about winter’s end, Dairy Queen is marking the occasion with a sweet deal: March 20 is Free Cone Day!

Participating stores—which Money notes “includes most locations outside of the company's stores in mall complexes”—are giving away one small vanilla cone to every customer at no charge, though donations are welcome. The event will benefit the Children's Miracle Network Hospitals, a nationwide nonprofit organization that raises money for children’s hospitals, medical research, and public awareness of various health issues affecting children. While donations are not required, a DQ spokesperson told Today that they are encouraged.

Charity has long been a part of Dairy Queen’s mission; the ice cream giant has raised more than $120 million for nonprofit organizations over the past 32 years.

If you can’t make it out for a cone on March 20, Ben & Jerry’s will be hosting its own Free Cone Day on April 4; mark your calendars!
