Is the birthday according to the lunar or solar calendar?

I don't know, the solar calendar is more accurate ~, but fortune telling is calculated according to the lunar calendar. I think it is better to calculate according to the lunar calendar ~ after all, it is something left by our ancestors, and fate is based on the lunar calendar. . .

And found a passage for the questioner,

The ancients counted birthdays according to the lunar calendar, and most folks continued this method, that is, counting birthdays according to the lunar calendar. It takes 60 years for the lunar calendar to be exactly the same as the solar calendar, which is often said that 60 years is a son, which is called the 60th birthday; If there is a leap month, there are two birthdays in a year to celebrate the previous birthday. However, there are exceptions. If you were born in the month after a leap month, you can celebrate the latter when you meet a leap month. There are people who can't celebrate their birthdays for a year. One of my friends is the thirtieth day of the twelfth lunar month. If there is no twelfth lunar month, there will be no birthday. Modern people are open-minded, and their personal ideas are eclectic. Some people celebrate their birthdays according to the solar calendar. In short, don't forget your mother's hard work and repay her kindness. It is not important to use the lunar calendar for birthdays.
