Sunday, July 16 is National Ice Cream Day, and lots of national chains are getting in on the fun!

The third Sunday in the month of July is National Ice Cream Day, and to mark the big occasion, lots of national chains are serving up free or discounted scoops and cones! Here's where you and your L.O.s can get in on the sweet action this weekend.

1. McDonald's - If summer usually has you craving a vanilla soft serve cone from McD's, you're in luck. If you download the McDonald's app, you'll be to snag a coupon for a free cone on Sunday. The chain is also offering a “lifetime supply” of the ice cream to the lucky patron who scores a Golden Arches Cone. One person at each participating location will be given the special cone between 2 p.m. and 5 p.m. (By the way, since the fall of 2016, the chain has shifted to a new kind of soft serve that contains no artificial flavors, colors, or preservatives. Even yummier!)

2. Friendly's - The family-friendly restaurant chain is doing a BOGO deal -- buy one cone, get another free on Sunday. And for every $2.99 Friend-z ice cream ordered on Sunday, the chain will donate $2 to the Boys & Girls Club of America. And if you participate in the Friend-z ice cream promo, the Boys & Girls Club of America and Friendly’s will give you thank you coupons toward your next Friendly’s visit.

3. 16 Handles - Download the app, and you can get a free 4-oz. frozen yogurt from noon to 5 p.m.

4. Baskin-Robbins -  The Baskin-Robbins mobile app will feature special offers for National Ice Cream Day.

5. Carvel - The ice cream chain will offer patrons a second free cup or cone with the purchase of your first one.

6. Dippin' Dots - Check with your local stores for the two-hour window during which they'll be celebrating National Ice Cream Day, and you can get a free mini cup of ice cream.

7. Krystal - Forget National Ice Cream Day! The chain will be celebrating for a week, selling sundaes for 99 cents from Sunday through July 23.

8. Marble Slab Creamery - If you're one of 25 people who visit the store on Sunday, you'll get a free cone.

9. Monkey Joe's - All guests at Monkey Joe's indoor play centers get free ice cream cups on Sunday.

10. Subzero - Hit up this futuristic chai from 2 p.m. to 6 p.m., buy one ice cream at regular price, and you'll get a second one for free.

11. Your Pie - Free gelatos all around on Sunday!

12. Wendy's - If a vanilla or chocolate Frosty is more your thing than ice cream, swing by your local Wendy's. Frosties are just 50 cents on National Ice Cream Day -- and through August 25!
