June is quickly getting away from us! I did not post the "official" spelling for all (two!) of the June US-nationally-recognized holidays, so here they are:
1. Flag Day
a. No possessives to deal with!
b. Capitalize both words as both are words in the actual holiday
c. Bonus: Great holiday since I was born on this date! :)
2. Father's Day
a. We went through this earlier--but remember--one father; his day: father's
b. Cap both words!
