April 20 is the 110th day of the year(111th in leap years) in the Gregorian calendar. 255 days remain until the end of the year.

A leap year is a calendar year containing one additional day added to keep the calendar year synchronized with the astronomical or seasonal year. Because seasons and astronomical events do not repeat in a whole number of days, calendars that have the same number of days in each year drift over time with respect to the event that the year is supposed to track. By inserting 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.

The Gregorian calendar is the calendar used in most of the world. It is named after Pope Gregory XIII, who introduced it in October 1582. The calendar spaces leap years to make the average year 365.2425 days long, approximating the 365.2422-day tropical year that is determined by the Earth's revolution around the Sun. The rule for leap years is:

Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the year 2000 is.

Cædwalla of Wessex 7th-century King of Wessex

Cædwalla was the King of Wessex from approximately 685 until he abdicated in 688. His name is derived from the Welsh Cadwallon. He was exiled from Wessex as a youth and during this period gathered forces and attacked the South Saxons, killing their king, Æthelwealh, in what is now Sussex. Cædwalla was unable to hold the South Saxon territory, however, and was driven out by Æthelwealh's ealdormen. In either 685 or 686, he became King of Wessex. He may have been involved in suppressing rival dynasties at this time, as an early source records that Wessex was ruled by underkings until Cædwalla.
