Another unit of time is the year. One year is equivalent to 365 1/4 days. However, our calendar does not include quarter days. Instead, we say that a year is 365 days, and every fourth year is a leap year of 366 days. If a year is divisible by 4, it is a leap year, unless it is a year at the beginning of a century not divisible by 400. 1600, 2000, 2004, 2008, and 2012 are leap years. 1700, 1800, and 1900 are not leap years. State whether the given year is a leap year.
