For holidays that occur on the same date each year, such as July 4th and New Year's Day, you can set yearly holidays.
Tip: You should only set a yearly holiday for holidays that occur on the same date each year. Other holidays, such as Thanksgiving or Memorial Day, occur on the same day of the week each year, but not the same date.
