Regex Tester & Validator

Matches dates in the format 'DD-Mon' where DD is a day from 1-31 (with optional leading zero) and Mon is a three-letter English month abbreviation (Jan, Feb, Mar, etc.). The regex uses word boundaries and is case-insensitive, making it suitable for parsing dates like '5-Apr' or '25-Dec'. Commonly used for log parsing, data extraction, or validating short-form dates.
