Leap It is a term that derives from the Latin word bisextus. The concept is used to refer to the leap-year : that year what's wrong with it 366 days ; that is, one day additional Regarding the common years. This extra day is added to the month of February , which in these cases has 29 days instead of 28 .
It should be remembered that a year is a period of weather which has an extension of twelve months . According to the Gregorian calendar, each day begins the day January 1 and ends the December 31 . After the month of January arrives February and then the months of March , April , may , June , July , August , September , October and November , until finally reaching December .
These twelve months usually add 365 days , which is the number of days a year has. Leap years are particular cases: February , which usually has 28 days , happens to have 29 . Thus leap years total 366 days .
Why do you add one day a year leap ? The explanation is found in the difference between the calendar year and the tropic year (as it is known while it takes the planet land in completing its orbit around the sun). The duration of the tropic year is 365 days, 5 hours, 48 minutes and 45 seconds . The lag between this duration and the 365 days of the calendar year is exceeded by adding, every four years, one day to the calendar year (equivalent to the uncounted time of the tropic year). That's why every four years there is a leap year: 2016 , 2020 and 2024 , for example, are leap years.
In addition to all the above about the leap term, we can establish another series of interesting data about it, such as the following:
-It is established that since February 29 there are only 306 days left before the year can end.
- Until now the last leap year was 2016 and it is established that the next one that will be is 2020.
- It is necessary to establish that there is the case in the whole world of numerous people who were born on February 29. So, they have no choice but to celebrate their birthday when it is not a leap year on February 28. Thus, for example, at the legal level in Spain it is indicated that these individuals turn years at 00:00 hours on February 28 those years in which there are no 29.
-Among the most important characters that were born on February 29 we can highlight both the Italian Pope Paul III and the American film director William A. Wellman (1896 - 1975), who was in charge of films such as "Buffalo Bill" ( 1944) or "Beyond the Missouri" (1951). However, we must not forget other figures such as the writer Dee Brown, the Spanish politician Pedro Sánchez or the footballer Darren Ambrose.
