How it works

This tool strictly evaluates input against RFC 5545 guidelines. It runs entirely locally in your browser using Alpine.js; no calendar data is transmitted to our servers.

Assumptions

  • Input strings must be UTF-8 encoded.
  • Line folding (CRLF followed by whitespace) is automatically unwrapped before parsing.
