Roman Numeral Tattoo Generator Reveals Hidden Complexities Beyond Simple Conversion

A developer building a Roman numeral tattoo generator discovered that accurate date conversion was only a small part of the challenge. Date format ambiguity — where the same numeric date can mean different things in different countries — required users to first confirm their intended date in written words before conversion. Additional complications arose from the absence of zero in traditional Roman numerals, meaning the tool converts whole number values rather than individual digits. Beyond conversion accuracy, the project evolved into a broader planning workflow addressing separator styles, font readability at tattoo scale, layout orientation, and physical size constraints. What began as a simple converter ultimately became a multi-step design tool to help users avoid permanent mistakes.
