We all know that most of these “National Whatever Days” were created for fun, profit, or both, without the faintest suggestion of being officially endorsed by any governmental entity. But today is different. In 1984, President Ronald Reagan proclaimed the third Sunday of July to be National Ice Cream Day. (He also made July National Ice Cream Month, and indeed, we’ll have more ice cream-related days on the 23rd and 25th). So whether you lean strawberry or blueberry (I’m a rocky road guy, personally), you can find an appropriate way to celebrate this important date. Lots of local and national chains are offering free or discounted ice cream today, so get out there and enjoy everyone’s favorite frozen dairy product.
