How important of the lunar calendar is in chinese metaphysics

Recently we received one request for bazi consultancy and that person provided us her lunar birthday, which is 26th of December in Jia Zi year. To convert into the solar calendar, her solar birthday is 15th Feb 1985. Accordingly her birth year is Yi Chou not Jia Zi like she thought.

Many Vietnamese misunderstand that the chinese lunar calendar is the soly calendar for calculating all year round’s important events including selecting good dates for every purposes, life destiny analysis, fengshui and so forth, thus when any good day selected coincidently is on the lunar days either the 3rd, 7th, 13th, 18th, 22nd, 28th, 5th, 14th, 23rd and any day from the whole month of the 7th lunar month, which is known as the ghost month to many people is considered to be unauspicious. In short according to them every calculation must rely on the lunar calendar, that is why there are many especially those from rural areas when asking about their birthdays, they provide us their lunar birthdays, and many parents even use their children’s lunar birthdays for registering their birth certificates and official personal documents as well as for their birthday celebrations.

The fact is the lunar calendar is used for calculating the chinese lunar new year and other moon festivals and for ziweiduoshu, one of chinese astrology methods. While the other important event calculations, such as date selections for ground breaking, house renovation, fengshui alteration, moving in, openning ceremony, wedding, bazi analysis and other chinese metaphysics are based on the heavenly stems and earthly branches calendar which is used the solar calendar for reference.

The lunar calendar is based on the moon system, each year consists of 12-13 lunar months with total of up from 383 to 385 days. While the solar calendar is based on the sun system, each year fixes of 12 months with total of days from 365 to 366 days. Each solar month consists of 2 seasonal qi, and there are 24 seasonal qi per a solar year, each day is named by a relevant heavenly stem and earthly branch, which is the key reference for ancient Chinese to use in Chinese metaphysics purposes, such as iching, fengshui, bazi, qi men dun jia, date selections, and in weather forecasting as well as for farming cultivation and harvesting.

Therefore, our advice is you dont need to remember and use your lunar birthday, but your solar one instead, as it is the key reference for multi purposed checking and to avoid any wrong belief from the mentioned case and in reality there are many people being born from the 3rd or the 4th of Feb of leap year, which the Chinese lunar new year comes afterward and misunderstanding that they are born from the previous celestial animal year. For instant, the lunar new year of Wu Xu 2018 will be on 16 Feb 2018 any babies born from the 4th of Feb of 2018 to the 15th of Feb of 2018, their birth year will belong to Wu Xu, not Ding You as the new year commencing from the Li Chuan, the starting seasonal qi in the 24 seasonal qi.
