Why does February have 28 days? Why 29 in leap years?
I was wondering why February only has 28 days.
That's a great question! The reason February only has 28 days is because it was added to the Roman calendar at a time when the year was divided into 10 months. At the time, February was the last month of the year and was only given 28 days because it was thought to be an unlucky month.
