您粘贴的正则表达式不能正确验证闰年，但有一个可以在同一帖子中.我将其修改为 dd/mm/yyyy、dd-mm-yyyy 或 dd.mm.yyyy.

The regex you pasted does not validate leap years correctly, but there is one that does in the same post. I modified it to take dd/mm/yyyy, dd-mm-yyyy or dd.mm.yyyy.

^(?:(?:31(/|-|.)(?:0?[13578]|1[02]))1|(?:(?:29|30)(/|-|.)(?:0?[13-9]|1[0-2])2))(?:(?:1[6-9]|[2-9]d)?d{2})$|^(?:29(/|-|.)0?23(?:(?:(?:1[6-9]|[2-9]d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))$|^(?:0?[1-9]|1d|2[0-8])(/|-|.)(?:(?:0?[1-9])|(?:1[0-2]))4(?:(?:1[6-9]|[2-9]d)?d{2})$

我在 Arun 在他的回答中提供的链接以及 此处 中对其进行了一些测试，它似乎有效.

I tested it a bit in the link Arun provided in his answer and also here and it seems to work.

编辑 2019 年 2 月 14 日:我删除了正则表达式中的逗号，该逗号允许诸如 29-0,-11

Edit February 14th 2019: I've removed a comma that was in the regex which allowed dates like 29-0,-11
