Earliest date for the autumnal equinox in the Northern Hemisphere and the vernal equinox in the Southern Hemisphere: Mabon in the Northern Hemisphere, Ostara in the Southern Hemisphere. (Neopagan Wheel of the Year)
Wheel of the Year
The Wheel of the Year is an annual cycle of seasonal festivals, observed by a range of modern pagans, marking the year's chief solar events and the midpoints between them. Modern pagan observances are based to varying degrees on folk traditions, regardless of the historical practices of world civilizations. British neopagans popularized the Wheel of the Year in the mid-20th century, combining the four solar events marked by many European peoples, with the four midpoint festivals celebrated by Insular Celtic peoples.
Ēostre
Ēostre is an Anglo-Saxon goddess mentioned by Bede in his 8th century work The Reckoning of Time. He wrote that pagan Anglo-Saxons had held feasts in her honour during the month named after her: Ēosturmōnaþ (April), and that this became the English name for the Paschal season: Easter.
Modern paganism
Modern paganism, also known as contemporary paganism and neopaganism, is a range of new religious movements variously influenced by the beliefs of pre-modern peoples across Europe, North Africa, and the Near East. Despite some common similarities, contemporary pagan movements are diverse, sharing no single set of beliefs, practices, or religious texts. Scholars of religion may study the phenomenon as a movement divided into different religions, while others study neopaganism as a decentralized religion with an array of denominations.
