The Anglo-Saxons called April Oster-monath or Eostur-monath, the period sacred to Eostre or Ostara, the pagan Saxon goddess of spring, from whose name is derived the modern Easter. St George's day is the twenty-third of the month; and St Mark's Eve, with its superstition that the ghosts of those who are doomed to die within the year will be seen to pass into the church, falls on the twenty-fourth. In China the symbolic ploughing of the earth by the emperor and princes of the blood takes place in their third month, which frequently corresponds to our April. The Finnish called this month Huhtikuu, or 'Burnwood Month', when the wood for beat and burn clearing of farmland was felled.
The "days of April" (journées d'avril) is a name appropriated in French history to a series of insurrections at Lyons, Paris and elsewhere, against the government of Louis Philippe in 1834, which led to violent repressive measures, and to a famous trial known as the procès d'avrill.
The birthstone of April is the diamond or the sapphire, and the birth flower is typically listed as either the Daisy or the Sweet Pea. However, a few questionable online sources also cite the Tulip, as well.
April starts on the same day of the week as July in all years, and January in leap years.
