365 full days. Because the Earth's orbit is not exactly divisible by full days, we add an extra day to the calendar during almost every 4th year. February 29th only occurs during these 'leap' years. To make things just a little more complicated, to keep the seasons and equinoxes correct without the calendar days shifting, any year divisible by 4 is a 'leap' year UNLESS the year is also divisible by 100. So, any year that is divisible by 100 is not a leap year unless it is also divisible by 400. It's simpler to just buy a calendar and count the days listed there!
