Regex Tester & Validator

This regex matches various formats of lease expiration dates or durations, including full dates (DD/MM/YYYY), month/year combinations, specific years (20XX), durations in months (e.g., "12 mois"), and textual dates (e.g., "1 Janvier 2024"). It is highly suitable for parsing lease agreements, contract expiration dates, and duration terms in French documents. The pattern captures both numeric and alphanumeric date representations.
