Roman Numeral Date Guide

Convert each component separately within 1–3999:

• Month 1–12 → I–XII
• Day 1–31 → I–XXXI
• Year → standard Roman year (example 2026 = MMXXVI)

Always label order: MM/DD/YYYY vs DD/MM/YYYY vs YYYY/MM/DD. Example August 8, 2026 → VIII / VIII / MMXXVI.

Ambiguous Arabic dates such as 04/07/2026 stay ambiguous in Roman form unless the order is stated.
