Are perpetual calendars and yellow calendars the same thing?

As we all know, the perpetual calendar is the oldest solar calendar in ancient legends of China. In order to commemorate the achievements of calendar compilers for thousands of years, this kind of calendar was named "perpetual calendar". The perpetual calendar currently in use is actually a kind of calendar, which records the dates of a specific solar calendar or lunar calendar within a certain time range (for example, 100 or longer) for the convenience of people in need.

The yellow calendar, also known as the old yellow calendar, the imperial calendar and the children's calendar, etc. , is a kind of almanac that can display various calendars such as Gregorian calendar, Lunar calendar and Ganzhi calendar at the same time, which contains a large number of rules and contents related to seeking good fortune and avoiding evil. No matter which version of the yellow calendar it is, it basically includes such basic information as solar terms, taboos, directions, etc., most of which are linked to the lunar calendar and lunar calendar, which is an important basis for most people to choose dates.

When we need to choose a date, we will look through the yellow calendar and choose a day marked "suitable", especially a day marked "taboo". However, due to the numerous versions of the yellow calendar, the labels of appropriate taboos among different versions are not exactly the same, and it may even happen that the same day is marked in this yellow calendar and the wedding is marked in another yellow calendar. Which one should we trust in this situation? At this time, we can choose a more authoritative Gregorian calendar, such as the prescription book of the King James Association in Siku Quanshu, or simply choose a festival where relatives and friends have time and the solar calendar is auspicious.

Generally speaking, the Gregorian calendar time of the old calendar and the perpetual calendar is basically the same. If you are particularly entangled in the choice of taboos, you can also choose a trusted master to ask, or simply read an authoritative almanac to choose the date according to your actual situation.
