Frequently Asked Questions

Does this validate the date is real?

No, this only checks format. It would accept 2024-02-31 even though February doesn't have 31 days. Use Date parsing for validation.

What regex flavor does this use?

This tester uses JavaScript regex (ECMAScript). Most patterns work the same in Python, Java, and other languages.
