The Month change
April comes between March and May, making it the fourth month of the year. It also comes first in the year out of the four months that have 30 days, as June, September and November are later in the year.
April begins on the same day of the week as July every year and on the same day of the week as January in leap years. April ends on the same day of the week as December every year, as each other's last days are exactly 35 weeks (245 days) apart.
In common years, April starts on the same day of the week as October of the previous year, and in leap years, May of the previous year. In common years, April finishes on the same day of the week as July of the previous year, and in leap years, February and October of the previous year. In common years immediately after other common years, April starts on the same day of the week as January of the previous year, and in leap years and years immediately after that, April finishes on the same day of the week as January of the previous year.
In years immediately before common years, April starts on the same day of the week as September and December of the following year, and in years immediately before leap years, June of the following year. In years immediately before common years, April finishes on the same day of the week as September of the following year, and in years immediately before leap years, March and June of the following year.
It is unclear as to where April got its name. A common theory is that it comes from the Latin word "aperire", meaning "to open", referring to flowers opening in spring. Another theory is that the name could come from Aphrodite, the Greek goddess of love. It was originally the second month in the old Roman Calendar, before the start of the new year was put to January 1.
Quite a few festivals are held in this month. In many Southeast Asian cultures, new year is celebrated in this month (including Songkran). In Western Christianity, Easter can be celebrated on a Sunday between March 22 and April 25. In Orthodox Christianity, it can fall between April 4 and May 8. At the end of the month, Central and Northern European cultures celebrate Walpurgis Night on April 30, marking the transition from winter into summer.
