php - Birthday field lunar calendar design problem, whether there is a wheel available.

Question

Requirements: There is a customer birthday field, which stores the customer's birthday, which may be in the solar calendar or the lunar calendar. Later, birthday text messages will be sent to wish the customer. Is the field design good? Birthday field (timestamp) Is the lunar calendar (int 0 or 1) wheel available? Does PHP have a ready-made wheel to handle the lunar and solar calendars?

The solar and lunar calendars are so important. Just cross one and you can pull it out by storing the timestamp in the field. Then you can calculate the lunar calendar by writing a class to calculate it

Is the field design good?

Are there any wheels?
