How can I validate a date format in my application?

How can I validate a date format in my application?

You can use regular expressions to check if the date matches a specific format, like YYYY-MM-DD.

Can you show me an example of a regex for that?

Sure! A regex for YYYY-MM-DD would be: ^\d{4}-\d{2}-\d{2}$. This checks for four digits, a dash, two digits, another dash, and two more digits.

What if I want to validate dates like MM/DD/YYYY?

For MM/DD/YYYY, you can use: ^\d{2}/\d{2}/\d{4}$. This ensures the format is two digits, a slash, two digits, another slash, and four digits.

How do I handle invalid dates, like February 30?

You can parse the date after validation and check if it results in a valid date object. If not, it's invalid.
