Does the weather change repeatedly according to the lunar calendar or the solar calendar?

The weather is short, usually one day. If you ask for a whole year, you should say "climate" or "season".

To put it bluntly, solar terms are the 24 points of the earth on the ecliptic. Since it is a point on the ecliptic, it is of course according to the solar calendar.

If you mean "climate", to be precise, "climate" is only related to your geographical location, not time.

If you are talking about seasons, you should know that in China, seasons are judged according to solar terms, of course, according to the solar calendar!

I read the other two answers and found that they misunderstood our calendar.

The traditional calendar in China is not a solar calendar or a lunar calendar, but a lunar calendar. The western calendar (commonly called Gregorian calendar) is a solar calendar, which is determined only according to the movement of the earth around the sun, and has nothing to do with the movement of the moon. The calendar used in Islamic countries (commonly called hijri) is the lunar calendar, which is determined only according to the movement of the moon and has nothing to do with the movement of the sun. In the China lunar calendar, the number of days in each month is determined according to the moon's profit and loss, which will make 12 month not a tropical year. Therefore, we stipulate that if there is only one solar term in a month (generally, there are two solar terms in a month), a leap month should be added behind it to correct it.

So we can't say that the solar calendar is foreign, but that China's calendar does not include the solar calendar.
