The Vernal Equinox was celebrated long before the Celts, by the Megalithic
people who lived in Britain before the Celts, the Romans and the Saxons. Ancient
Greeks, Ancient Romans, Ancient Mayans all celebrated the equinox, as did Native
Americans. Ancient Persians called it NawRaz, their New Year's Day.
A cluster of megalithic cairns from ancient times are scattered through the hills at Loughcrew, about 55 miles northwest of Dublin, Ireland. Loughcrew Cairn T is a passage tomb which is designed so that the light from the rising sun on the spring and summer equinoxes penetrates a long corridor and illuminates a backstone, which is decorated with astronomical symbols.
This year’s vernal equinox occurs on Wednesday, at exactly 11:02 Coordinated Universal Time (UTC), or 7:02 a.m. Eastern Daylight Time, ushering in spring in the Northern Hemisphere and autumn for the Southern. The time of the equinox marks when the center of the sun shines down right on the equator.
After the equinox, the sun's observed path through the sky will appear to creep north of the equator as the Earth orbits the sun. Thanks to our planet's tilted axis, the Northern Hemisphere will be increasingly inclined toward the sun in the coming months, easing us into the warmer seasons.
