Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A leap year (or intercalary year) is a year containing one extra day (or, in the case of lunisolar calendars, in a month) in order to keep the calendar year synchronized with the astronomical or seasonal year. For example, in the Gregorian calendar (common calendar), February in a leap year has 29 days instead of the usual 28 so the year lasts 366 days instead of the usual 365. Because seasons and astronomical events do not repeat in a whole number of days, a calendar that had the same number of days in each year would, over time, drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected. A year that is not a leap year is called a common year.
