Regex Tester & Validator

This regex matches time values in a 24-hour HH:MM format, where the hour can optionally be a single digit (e.g., "9:30" or "09:30"). It strictly validates that the hours range from 0 to 23 and the minutes range from 00 to 59. With the global and multiline flags enabled, it is perfectly suited for extracting or validating multiple time entries from a multi-line text block.
