Hardee's biscuits are one of the main reasons its locations are hit hard during breakfast. It's the only time this popular item is used as buns for breakfast sandwiches.
Hardee's is open for breakfast every day of the year, with the exception of Christmas Day but if you’re annoyed that breakfast isn't served all day, don't take it out on Hardee's.
According to a Facebook post from 2019, Hardee's did try extending breakfast hours until 2 p.m. for a limited time but is now back to its 10:30 a.m. end time.
