请问如何调用今天的日期呢?

其实我是想让游客感觉我每天都在更新,但是我并不会每天都更新.我希望能调用每天的新日期,比如今天是2022-4-19,明天游客浏览就自动变成了2022-4-20.这样的话,该用什么代码呢?
In fact, I want to make the tourists feel that I am updating every day, but I do not update every day. I hope to be able to call the new date every day, for example, today is 2022-4-19, and the visitor browsing tomorrow will automatically become 2022- 4-20. In this case, what code should I use?
