Fro-yo girl here. I really don't know when National Frozen Yogurt Day is or how many there are per year. I'm celebrating National Frozen Yogurt Day on February 6th and June 4th. Though there are several websites dedicated to food holidays, I can't tell which ones are the most accurate and trustworthy. According to these types of sites, there is a National Frozen Yogurt Week and a National Frozen Yogurt Month as well.
Why can't every day be frozen yogurt day? Be sure to eat some fro-yo today. And if you're in SoCal, check out the Tuttimelon grand opening (free fro-yo from 12-2 PM) at Ontario Mills. Congrats Tuttimelon!
According to these sites, National Frozen Yogurt Day is February 6:
This site says National Frozen Yogurt Day is June 1st:
There's evidence that National Frozen Yogurt Day is June 4th:
And another site says National Frozen Yogurt Day is July 1:
We can't forget National Frozen Yogurt Week: May 24 - May 30: http://www.cdkitchen.com/recipes/articles/view/48/1/National-Frozen-Yogurt-Week.html

You know you love me. X0 X0, fro-yo girl.
