The vernal equinox happens every year, yet most people don't know what it is or why it's important. Here's the scientific—and spiritual—scoop on the first day of spring.
Seasons change all the time. The changing of the seasons is either a solstice or an equinox. The beginning of spring is known as the vernal equinox. Let's find out how it happens
The Persian calendar begins each year at the northward equinox, observationally determined at Tehran. [15] The Indian national calendar starts the year on the day next to the vernal equinox on 22 March (21 March in leap years) with a 30-day month (31 days in leap years), then has 5 months of 31 days followed by 6 months of 30 days.

Vernal equinox and autumnal equinox: these classical names are direct derivatives of Latin (ver = spring, and autumnus = autumn). These are the historically universal and still most widely used terms for the equinoxes, but are potentially confusing because in the southern hemisphere the vernal equinox does not occur in spring and the autumnal ...
The Met Office explains the difference between meteorological spring and astronomical spring
At the spring equinox, also called the vernal equinox, days and nights are approximately twelve hours long, with daytime length increasing and nighttime length decreasing as the season progresses until the summer solstice. The spring equinox is in March in the Northern Hemisphere and in September in the Southern Hemisphere, while the summer ...
Given the different Sun incidence in different positions in the orbit, it is necessary to define a standard point of the orbit of the planet, to define the planet position in the orbit at each moment of the year w.r.t such point; this point is called with several names: vernal equinox, spring equinox, March equinox, all equivalent, and named considering northern hemisphere seasons.
The equinox arrives on Saturday, marking the start of the fall season for the Northern Hemisphere. Here's what to know about how we split up the year using the Earth's orbit. As the Earth travels ...
