Regex Editor & Tester

Matches dates in US format (MM/DD/YYYY) using three named capture groups: month (1-2 digits), day (1-2 digits), and year (exactly 4 digits), separated by forward slashes. Ideal for substitution-based reformatting, such as converting US dates to ISO 8601 (YYYY-MM-DD) with a replacement like ${year}-${month}-${day}. The global and multiline flags allow processing multiple dates across every line in a document.
