Regex Editor & Tester

This regex validates dates in DD/MM/YYYY, DD-MM-YYYY, or DD.MM.YYYY format, ensuring day (01-31), month (01-12), and a 4-digit year. It uses a backreference to require a consistent separator (/, -, or .) between day, month, and year. Common use cases include form validation for date inputs or extracting dates from text.
