How many more days in the year

There are 365 days in a year. A leap year has an additional day, making it 366 days long. The average year length is 365.2425 days. 1. **Leap Years**: A leap year occurs every four years, with the exception of years that are divisible by 100 but not by 400. This is because the Earth's orbit around the sun takes approximately 365.2425 days, and adding an extra day every four years helps keep the calendar year aligned with the solar year. 2. **Days in a Leap Year**: In a leap year, the month of February has 29 days instead of the usual 28. This adds an extra day to the year, making the total number of days in a leap year 366.
