Is the winter solstice the latest day of sunrise?

To answer this question, we must first know what the winter solstice is like.

We know that the earth moves around the sun and its motion is relative. On the earth, it seems that the sun goes around the earth. This orbit is called the ecliptic. People divide the ecliptic into 360 degrees to record the exact position of the sun on the ecliptic, just like the longitude of the earth. The longitude of the ecliptic is called the zodiac.

The solstice in winter is the moment when the sun is at 270 degrees of the yellow meridian, which may be noon or midnight. Therefore, the day when the sun rises at the latest is not necessarily the day of the winter solstice, but depends on the time when the winter solstice is handled the next day. Which sunrise is closest to the winter solstice and which sunrise is the latest.

For example: 65438+3: 00 am on February 22 is the winter solstice, and the sunrise closest to this moment is of course the sunrise on February 22, 65438, which happens to be the latest sunrise from winter to day;

However, if the winter solstice is 65438+23: 00 on February 22, then the latest sunrise is obviously 65438+23: 00 on February 23, so the latest sunrise is not the winter solstice, but the second day of the winter solstice.
