Скачать или смотреть First Day of Spring 2023: The Spring Equinox

The first day of spring in 2023 is Monday, March 20. This date marks the "spring equinox" in the Northern Hemisphere. The spring equinox occurs when the Sun crosses the celestial equator going south to north. It is called the "celestial" equator because it is an imaginary line in the sky above the Earth's equator.
The vernal equinox, or spring equinox, marks the official start of spring regardless of what the weather is doing outside. The word "vernal" translates to "new" and "fresh," while "equinox" comes from Latin words meaning "equal night". On this day, there are approximately equal amounts of daylight and darkness all over the world.
There has been some discussion about whether spring is getting shorter. According to , current seasonal lengths for the Northern Hemisphere are approximately: summer - 93.641 days, autumn - 89.834 days, winter - 88.994 days, and spring - 92.771 days. As a result, warm seasons (spring and summer) combined are about 7.584 days longer than colder seasons (fall and winter). However, it's important to note that these numbers are approximate and can vary from year to year depending on various factors such as leap years and other astronomical events.
