Test, validate and match regular expressions
Matches dates in MM/dd/yyyy format with optional leading zeros on month and day. Validates months from 01-12, days from 01-31, and years from 1900-2099. Commonly used for validating US-format date inputs in web forms, though it doesn't verify actual calendar correctness (e.g., allows Feb 31).
