v2.4.2: Select February 30th of the lunar year causes Unexpected Application Error!

[LucasJi]

描述（Description）

Just as the title says, when selecting Feb 30, the online astrolabe shows an error page.

I would appreciate it if the author could add exception handling. This would make not only this library but also the React hook iztro-hook more flexible for other developers in resolving exceptions.
