When is the vernal equinox in 2023? How many minutes and seconds?

The vernal equinox in 2023 is 5: 24: 14 seconds.

Traditionally, spring is between beginning of spring and Long Summer, and the vernal equinox is in the two solar terms, which just divides spring equally. At the vernal equinox, the sun shines directly on the equator, and the length of day and night is equal, each being 12 hour. In addition, the climate of the vernal equinox is characterized by warm and sunny weather. At this time, China folks have the custom of flying kites, eating spring vegetables and laying eggs.

The exact time of the spring equinox in 2023 is 5: 24 am on March 2 1 day, 14 seconds (Tuesday). The solar terms of the vernal equinox usually fall on March 19-22 of the Gregorian calendar every year, but the vernal equinox is usually from March 20 to 2 1. The corresponding lunar date is not fixed, usually in February.

On the day of the vernal equinox, the sun shines almost directly on the equator of the earth, and the whole world is almost as long as day and night (regardless of the refraction of the sun's light by the atmosphere and the shadow in the morning). The seasons in the northern and southern hemispheres are opposite. In the northern hemisphere, it is the vernal equinox, and in the southern hemisphere, it is the autumnal equinox. At the vernal equinox, the direct point of the sun is on the equator. Theoretically speaking, the length of day and night in the world is equal (see Twilight). After the vernal equinox, the direct point of the sun continued to move northward, and the days in the northern hemisphere became longer and shorter, and the nights in the southern hemisphere became shorter and shorter.

At the vernal equinox, there are no extreme days and nights in the world. After the vernal equinox, it began to be extremely daytime near the North Pole, and its scope gradually expanded. Near the Antarctic, the extreme day ends and the extreme night begins, and the scope gradually expands.
