Birthday is the most important day of the year. To celebrate their birth, many people hold birthday parties on their birthday. Some also use this opportunity to thank their mothers. However, in our country, there are generally two ways to celebrate birthdays. The first is the solar calendar (Gregorian calendar), and the other is the lunar calendar. Let's now take a look together: Does the lunar birthday change every year? Is fortune-telling based on the lunar birthday?

Does the lunar birthday change every year?

The lunar date of the lunar birthday is fixed, but the solar time will vary.
The opposite is also true.
The lunar calendar is based on the cycle of the moon's phases, with each phase change from new moon to full moon being a month;
The solar calendar is based on the annual apparent motion cycle of the sun, dividing one year into 12 months.
In other words, the calculation methods of the lunar and solar calendars are completely different, so the corresponding dates are naturally different.
However, to keep the difference between the lunar and solar calendars stable, an intercalary month is added to the lunar calendar,
so the dates of the lunar and solar calendars do not differ too much every year.

Is fortune-telling based on the lunar birthday?

It is recommended to provide the solar birthday and the 24-hour time (if you don't remember the exact time, it's still possible to calculate with just the year, month, and day),
due to the fact that the expressions and understandings of the person seeking divination vary greatly,
to avoid ambiguity and incorrect guidance for the fortune teller.
