Regex Tester & Validator

This regex parses activity diary schedule lines, extracting structured fields such as participant name, a single uppercase language code, optional lab information, a date in DD/MM/YYYY format, the day of the week in words, a start and end time (HH:MM), and a center identifier. It is designed for PCRE with named groups and global/multiline flags, useful for reading tabular or space-separated diary entries in log or configuration files.
