Regex Editor & Tester

This regex matches dates written in Spanish words, following a format like '[day] de [month] de/del [año] [year]'. It recognizes day numbers (uno-treinta y uno), all Spanish month names (enero-diciembre), and years written as words (like 'dos mil veintiuno'). Useful for parsing Spanish-language documents, extracting spelled-out dates, or validating date entries in Spanish forms or text processing applications.
