Year
What is a year?
The year is an important unit of time. It is the time it takes the earth to complete one cycle around the sun. Approximately the earth needs 365.24 days to make its complete cycle.
You may have noticed that each 4 years we have an extra day in February...why?
Simply, calendars fix the year at 365 days. The 4 missing quarters of days are added together to make one day each 4 years.
