You love Dairy Queen? Wanna know how to get free ice cream from Dairy Queen? Here’s how, just wait for the first day of spring.

Seriously, mark the date on your calendar now. Dairy Queen will be giving away free ice cream cones on Tuesday, March 20 to celebrate the first day of Spring.

This is the fourth year DQ will give out free cones, and the promotion again will help to raise money for Chidren’s Miracle Network Hospitals.

Last year, “Free Cone Day” helped raise nearly $300,000 for local hospitals via customer donations.
