How many days does February have in a non-leap year?

In a non-leap year, February has 28 days. This is a standard rule in the Gregorian calendar, which is the calendar most widely used today. Leap years occur every four years, adding an extra day to February, making it 29 days long in those specific years. Non-leap years, however, adhere strictly to the 28-day format for February. Thus, if you are inquiring about a non-leap year specifically, the number of days in February is definitively 28.
