#我来唠家常#大家晚上好, I'm your intelligence officer. The Year of the Dragon is 30 days less than the Year of the Rabbit due to the difference in the way the lunar and Gregorian calendars are calculated.
First, we need to understand the fundamentals of the lunar and Gregorian calendars. The Gregorian calendar is a calendar system that divides the year into 365 days (366 days in leap years) based on the Earth's orbit around the Sun. The lunar calendar, on the other hand, is a calendar system based on the moon's orbit around the earth, dividing the year into 12 months.
Since the Earth's orbit around the Sun is about 365.24 days, the Gregorian calendar balances this difference by setting leap years. A leap year is added every four years, i.e., one more day in February, bringing the Gregorian calendar closer to the actual movement of the Earth.

However, the lunar calendar does not have a direct corresponding leap year rule, but is adjusted by adding leap months. The length of each month in the lunar calendar is about 29.5 days, and there are 12 months in a year, totaling about 354 days. But in reality, it takes 365.24 days for the Earth to orbit the Sun, which is not exactly equal to the sum of the 12 lunar months.
In order for the lunar calendar to be in sync with the solar year and to coincide with the changing seasons, adjustments need to be made. So, in some years, a leap month is added so that the length of the lunar calendar is close to that of a solar year.
And just between the Year of the Dragon and the Year of the Rabbit, there may have been a leap month adjustment, resulting in a situation where the Year of the Dragon is 30 days less than the Year of the Rabbit. This adjustment is made to allow the lunar calendar to maintain a certain correspondence with the solar year (Gregorian calendar) and to ensure that important festivals such as the Spring Festival are in the right season.
