As you know, I am a huge fan of National Fun Holidays because often times it means free food or even deals on food. I tell people calories don't count when it's free but hey if you do every national day, those calories will add up! Hahahaha!
Here is a list day by day in August that you can expect to get a good deal or free food based on national holidays!
The list includes a bunch of ongoing deals as well too. For example, McDonald's is celebrating their 50th anniversary which means you get a free Big Mac and every Friday you can get free fries too!
