29 February
February 29 is a '' leap day'' (or "leap year day")—an intercalary date added periodically to create leap years in the Julian and Gregorian calendars. It is the 60th day of a leap year in both Julian and Gregorian calendars, and 306 days remain until the end of the leap year. It is the last day of February in leap years only. It is also the last day of meteorological winter in the Northern Hemisphere and the last day of meteorological summer in the Southern Hemisphere in leap years. In the Gregorian calendar, the standard civil calendar used in most of the world, February 29 is added in each year that is an integer multiple of four, unless it is evenly divisible by 100 but not by 400. For example, 1900 was not a leap year, but 2000 was. The Julian calendar— since 1923 a liturgical calendar—has a February 29 every fourth year without exception. Consequently, February 29 in the Julian calendar, since 1900, falls 13 days later than February 29 in the Gregorian, unti ...

April
April is the fourth month of the year in the Gregorian and Julian calendars. Its length is 30 days. April is commonly associated with the season of spring in the Northern Hemisphere, and autumn in the Southern Hemisphere, where it is the seasonal equivalent to October in the Northern Hemisphere and vice versa. History The Romans gave this month the Latin name '' Aprilis''"April" in '' Chambers's Encyclopædia''. London: George Newnes, 1961, Vol. 1, p. 497. but the derivation of this name is uncertain. The traditional etymology is from the verb ''aperire'', "to open", in allusion to its being the season when trees and flowers begin to "open", which is supported by comparison with the modern Greek use of άνοιξη (''ánixi'') (opening) for spring. Since some of the Roman months were named in honor of divinities, and as April was sacred to the goddess Venus, her Veneralia being held on the first day, it has been suggested that Aprilis was originally her ...
