​When is the first day of spring 2025? Know more about the vernal equinox

Winter has bid farewell, and springtime is just around the corner, set to bring longer days, blooming flowers, and a renewed sense of warmth. The first day of spring represents the vernal equinox in the Northern Hemisphere, which occurs when the sun aligns with the Earth’s equator.
In the Southern Hemisphere, however, this equinox is known as the autumnal equinox, as it represents the start of fall, when it tilts away from the sun, resulting in cooler weather and shorter days.
Let’s take a closer look at the springtime season in the Northern Hemisphere.

What is a vernal equinox?
The start of the spring season in the Northern Hemisphere is known as the vernal equinox. The vernal equinox occurs when the Sun crosses the celestial equator heading north, marking the start of spring in the Northern Hemisphere. When the Sun hits this sweet spot, day and night are nearly equal, about 12 hours each.

Equinoxes occur only twice a year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes. These events signal herald the beginning of spring and autumn. The word equinox is derived from two Latin words - aequus (equal) and nox (night).
The equinox that occurs during the Northern Hemisphere's fall is called an autumnal equinox.
Significance

Spring is a transition. The winter’s chill fades, and the Northern Hemisphere tilts toward the Sun again. This is a time for planting crops, outdoor activities, and watching the world turn green.
During spring, days in the Northern Hemisphere grow longer as the region gradually tilts more toward the sun, reaching its maximum tilt during the summer solstice. In the Spring of 2025, one can also expect a mix of rain showers, occasional late snow in northern climes, and increasingly sunny days. “April showers bring May flowers” holds true for many areas.
