A leap year, simply put, is a year that contains an extra day – February 29th – in order to balance the calendar year with the astronomical year. While a standard year has 365 days, a leap year boasts 366 days, ensuring that the calendar remains in sync with Earth’s revolutions around the sun.

A calendar year is typically 365 days long. These so called “common years” loosely define the number of days it takes the Earth to complete one orbit around the Sun. But 365 is actually a rounded number. It takes Earth 365.242190 days to orbit the Sun, or 365 days 5 hours 48 minutes and 56 seconds. This “sidereal” year is slightly longer than the c...
Some simple math will show that over four years the difference between the calendar years and the sidereal year is not exactly 24 hours. Instead, it’s 23.262222 hours. Rounding strikes again! By adding a leap day every four years, we actually make the calendar longer by over 44 minutes. Over time, these extra 44+ minutes would also cause the season...
Well, a common year is 52 weeks and 1 day long. That means that if your birthday were to occur on a Monday one year, the next year it should occur on a Tuesday. However, the addition of an extra day during a leap year means that your birthday now “leaps” over a day. Instead of your birthday occurring on a Tuesday as it would following a common year...
Jan 1, 2012 · Any year evenly divisible by four is a leap year, except centesimal years (years ending in two zeros) which are considered common years and thus have the typical 365 days, unless they are evenly divisible by 400. Therefore, 1600 and 2000 are leap years, while 1700, 1800, 1900 and 2100 are not.
Jan 2, 2021 · A leap year is a year with 366 days, instead of the usual 365. Leap years are necessary because the actual length of a year is nearly 365.25 days, not 365 days as commonly stated. Leap years occur every four years, and years that are evenly divisible by four (2020, for example) have 366 days.

A leap year is a year that does not have 365 days like a normal year, but 366 days. The additional day ("leap day") is the 29th of February. A leap year occurs only every four years (for exceptions see below).
1860 ( MDCCCLX) was a leap year starting on Sunday of the Gregorian calendar and a leap year starting on Friday of the Julian calendar, the 1860th year of the Common Era (CE) and Anno Domini (AD) designations, the 860th year of the 2nd millennium, the 60th year of the 19th century, and the 1st year of the 1860s decade.
