Convert any calendar date to Roman numerals and back. Supports DD.MM.YYYY, MM/DD/YYYY, and YYYY format. Instantly converts today's date with one click. Handles tattoo-style (VI·XIV·MCMXCIX), inscription-style, and full long-form formats.
Click the Today button to instantly convert the current date. Or select a date using the date picker, or type a date in DD/MM/YYYY, MM/DD/YYYY, or YYYY format. The converter handles any date from 1 AD to 3999 AD.
Select from three styles: Dot-separated (VI·XIV·MCMXCIX) — the most common tattoo and memorial style; Slash-separated (VI/XIV/MCMXCIX) — for general use; Long-form (the sixth day of the sixth month, in the year MCMXCIX) — for formal inscriptions and certificates.
Switch to Decode mode to convert a Roman numeral date back to a standard calendar date. Paste a dot-separated or slash-separated Roman numeral date and the tool interprets and validates it. The result shows the full date in multiple calendar formats.
Roman numeral dates are popular in tattooing and memorial inscriptions because they look elegant, have a timeless classical aesthetic, are more visually interesting than plain numbers, and feel more permanent and formal — qualities associated with significant life events like births, weddings, and memorials. The dot-separated format (VI·XIV·MCMXCIX) has become the standard tattoo style, popularised by athletes, musicians, and celebrities displaying meaningful dates.
The most common tattoo format is the American date order (MM·DD·YYYY) separated by dots or middle dots: month in Roman numerals · day in Roman numerals · year in Roman numerals. For example, June 14, 1999 becomes VI·XIV·MCMXCIX. Some people use the European order (DD·MM·YYYY). The dots can be solid bullets, stars, or decorative separators depending on the tattoo design.
Years are written as their numeric value in Roman numerals. 2024 = MMXXIV (MM=2000, XX=20, IV=4). 1999 = MCMXCIX (M=1000, CM=900, XC=90, IX=9). 2000 = MM. 1776 = MDCCLXXVI. For years before 1000, only three or fewer characters are needed: 476 = CDLXXVI, 44 = XLIV, 1 = I. The tool handles all valid years from 1 to 3999.
Roman numeral dates appear in film copyright notices (© MMXXIV instead of © 2024), at the end of television programmes and films, on cornerstones and building foundation stones (commemorating construction year), on monuments and memorials, on diplomas and formal certificates, in church inscriptions and epitaphs, and on clock and watch faces for the year of manufacture.
2024 in Roman numerals is MMXXIV. Breaking it down: MM = 2000, XX = 20, IV = 4. So 2000+20+4 = 2024. Similarly: 2025 = MMXXV, 2026 = MMXXVI, 2000 = MM, 1999 = MCMXCIX, 1900 = MCM, 2100 = MMC.
This tool converts dates in the Anno Domini (AD/CE) calendar system, which begins at year 1. Roman numerals have no concept of zero or negative numbers, so BC/BCE dates cannot be expressed in standard Roman numeral notation. Historical Roman dates were typically expressed as years from the founding of Rome (AUC — Anno Urbis Conditae) or as years in the consulship of named Roman officials.
