Convert Dates to Roman Numerals
Write years, wedding dates, and anniversaries in Roman numerals for invitations and commemorative designs.
Common values
Roman numeral rules: I=1, V=5, X=10, L=50, C=100, D=500, M=1000.
Subtractive notation: IV=4, IX=9, XL=40, XC=90, CD=400, CM=900. Standard numerals max out at MMMCMXCIX (3999).
Vinculum: a bar over a numeral multiplies it by 1000 (V̅ = 5000, X̅ = 10000, M̅ = 1,000,000), extending the range to 3,999,999.
Dates tips
Wedding date tattoos and invitations often use Roman numerals: XII · VI · MMXXIV (June 12, 2024). Convert each part separately.
Anniversaries in Roman numerals: 25th = XXV, 50th = L, 100th = C. Convert the year or the number of years as needed.
Movie copyright dates use Roman numerals. MMXXIV = 2024. The "from-Roman" mode lets you decode a year you see in film credits.
For design use, copy the Roman numeral result and paste it directly into Canva, Figma, or any design tool for your project.
