I definitely did NOT copy paste this from the Mcdonalds faq Page:
When does Mcdonald’s close?
In the United States, approximately a quarter of McDonald’s restaurants remain open 24 hours. They stay open seven days a week and 24 hours a day, they only close for two days in the year first is Christmas Day and the second is Easter Sunday.
The rest of the restaurants mostly close at 11:00 pm, and it starts serving the breakfast menu from 5:00 am till 10:30 am and after that, the lunch hours start till the closing time.
These McDonald’s closing times are not officially by McDonald’s, the owners of the franchise can set their opening and closing times, but most of the franchises work under the same time which is mentioned above.
