What is the exact time of beginning of spring in 20 10?

The Year of the Tiger has always been called "the year without spring" and "the year of widowhood", so the beginning of spring time of the Year of the Tiger has received unprecedented attention.

In my previous blog, I explained that "no spring year" is not a "widow year". Interested friends can have a look.

Recently, many friends asked about the exact beginning of spring time of 20 10, saying that there are several different versions online and in the almanac.

Version 1:

February 4th, 2065438, 06:52+00 beginning of spring (December 21st in Shi Mao).

Version 2:

Beginning of spring time in 20 10 is 06: 48 on February 4th (December 21st in Shi Mao lunar calendar).

The third edition:

The beginning of spring time in 20 10 is 02: 42 on February 4th (the ugly time of 2 1 month in the lunar calendar).

In 2009, I answered this question to netizens. Last year, there was a great difference in beginning of spring time between different versions, even more than ten days. In contrast, the beginning of spring time of 20 10 is the same in date, which is concentrated on February 4th, but the difference is only accurate to the hour.

This effect is relatively small. The most vulnerable are those babies who will be born on February 4.

Determine that the zodiac is based on beginning of spring. So, is the baby born on February 4, 20 10 a cow or a tiger? Which beginning of spring time should be used to determine?

The exact start time of the spring time of 20 10 is February 4th, 20 10 (about the morning of February 4th 1: 23). Taking this as a boundary, the baby born before is a cow, and the baby born after is a tiger.

Because beginning of spring is the real beginning of the Lunar New Year, time in beginning of spring is very important.

The ancients defined beginning of spring as the first of the 24 solar terms. On the day of beginning of spring, looking up at the starry sky at seven o'clock in the evening, we can see that the bucket handle of the Big Dipper points to the northeast, that is, the azimuth angle is 45 degrees, which was called the direction of Gen (one of the eight diagrams) by the ancients.

Beginning of spring is not only the first of the 24 solar terms, but also an important festival. In the astronomical sense, it marks the beginning of spring, while in Yi-ology, everything starts again in Yin and Yang, marking the real beginning of a new year.
