How to calculate the lunar birthday?

Traditionally, everyone celebrates the Lunar Birthday.

Lunar calendar is a traditional calendar in China. It also has the names of lunar calendar, lunar calendar, summer calendar, lunar calendar and lunar calendar. However, the lunar calendar is not a lunar calendar, but a combination of yin and yang. Take the cycle of the moon phase as the length of the month and the year of the return of the sun as the age. By setting 24 solar terms and leap months, the average calendar year can adapt to the tropic year. According to the fact that Emperor Xuanyuan, the ancestor of China, ascended the throne for the first year, this year is the Year of the Dog (Gregorian calendar 2018.02.16 ~ 2019.02.04). The traditional calendar in China is 2697 years earlier than the Gregorian calendar, and the year is +2008.02.04.

The calculation of solar terms and the time of the first lunar month is based on East longitude 120 degrees and China Standard Time.
