What is the Vernal Equinox?

The term “vernal equinox” derives from Latin, where “vernal” means spring and “equinox” means equal night. It refers to the moment when the Sun crosses the celestial equator, moving northward. This event results in nearly equal hours of daylight and darkness across the globe

The vernal equinox (or Spring equinox), is one of two equinoxes that occur annually, the other being the autumnal equinox in September.

When Does It Occur?

The vernal equinox typically occurs on March 20th or 21st in the Northern Hemisphere

This year, it falls on March 20th, 2025, at precisely 9:01 a.m. BST

The exact timing can vary slightly each year due to the Earth’s elliptical orbit and leap year adjustments.

Significance of the Vernal Equinox

The vernal equinox holds great significance both astronomically and culturally. Astronomically, it marks the point at which the Earth’s axis is not tilted toward or away from the Sun, resulting in nearly equal daylight and night hours

This balance is a reminder of the Earth’s intricate dance around the Sun and the changing seasons.

Culturally, the vernal equinox has been celebrated for centuries as a time of rebirth and renewal. Many ancient civilisations, including the Egyptians and Mayans, built monuments aligned with the equinox to mark the changing seasons

Today, it continues to be a symbol of new beginnings and the triumph of light over darkness.

How the Vernal Equinox Impacts Us

The vernal equinox has several effects on both humans and the natural world. For humans, it signifies the end of winter and the arrival of spring, bringing longer days, warmer temperatures, and a sense of rejuvenation.

This change in season can positively impact mood and energy levels, as increased daylight encourages outdoor activities and social interactions.

In the natural world, the equinox triggers various biological processes. Plants begin to bloom, animals come out of hibernation, and migratory birds return to their breeding grounds

The balance of light and darkness also influences ecosystems, promoting growth and renewal.
