Tool Introduction
Turning a date into Roman numerals is a popular way to mark something meaningful: a wedding date on a ring, a birthday on a bracelet, a founding year on a logo, or an anniversary on an invitation. The tricky part is that Roman numerals do not have a single agreed layout: some people write the day first, others the month first, and the punctuation between the parts varies too. This converter builds every common variant at once, so you can pick the one that matches your design instead of doing the math and formatting by hand.
Enter a day, month, and year (or click "Today" to use the current date), and the tool instantly shows the Roman numeral version with dots, dashes, slashes, spaces, the year on its own, and a stacked three-line layout that is especially popular for tattoos. A European (day.month.year) and US (month.day.year) order toggle lets you match local conventions. You can also work backwards: paste in a Roman numeral date you found somewhere and convert it back into a normal, readable date.
How to Use the Roman Numeral Date Converter
- Pick "Date → Roman numerals" mode (selected by default)
- Choose whether you want European (day.month.year) or US (month.day.year) order
- Enter the day, month, and year, or click "Today" to fill in the current date
- Browse the generated formats: dots, dashes, slashes, spaces, year alone, and the stacked layout
- Click "Copy" next to the format you want to use
- To go the other way, switch to "Roman numerals → Date" and paste in a Roman numeral date to decode it
Months in Roman Numerals
Since months only go from 1 to 12, their Roman numeral form never changes. Here is the full reference table:
- January = I
- February = II
- March = III
- April = IV
- May = V
- June = VI
- July = VII
- August = VIII
- September = IX
- October = X
- November = XI
- December = XII
Example Dates
A few worked examples so you can sanity-check the tool's output:
- A wedding date, September 21, 2019, becomes XXI.IX.MMXIX in day.month.year order, popular for engraving inside a ring.
- A birthday, April 23, 1990, becomes XXIII.IV.MCMXC in day.month.year order, or IV.XXIII.MCMXC in US month.day.year order.
- A single founding year, 2011, is simply MMXI, useful for logos, certificates, or building cornerstones where only the year matters.
Common Use Cases
- Tattoo designs marking a wedding, birth, or memorial date
- Engraving a date inside a wedding ring or on a watch
- Adding a founding year to a logo, letterhead, or building plaque
- Decorative invitations, save-the-dates, or anniversary cards
- Checking or double-checking a Roman numeral date you saw elsewhere

FAQs
How do I write a date in Roman numerals?
Convert the day, month, and year to Roman numerals separately, then join them with a separator. For example, July 12, 2024 becomes XII.VII.MMXXIV in day.month.year order, or VII.XII.MMXXIV in month.day.year order. This tool does that conversion for you and shows every common separator side by side.
Should I use day-month-year or month-day-year order?
It depends on your audience. Most of the world (Europe, Latin America, most of Asia) reads dates as day.month.year, while the United States commonly uses month.day.year. If the date is for a tattoo or engraving meant for someone specific, use whichever order feels most natural to them. This tool lets you switch between both with the order toggle.
Why is there no Roman numeral for the year 0 or years above 3999?
The Romans never used a symbol for zero, and the standard combination of I, V, X, L, C, D, and M symbols tops out at 3999 (MMMCMXCIX). Writing 4000 would require repeating M four times, which breaks the traditional three-repetition rule, so classical Roman numerals are conventionally capped at 3999.
Can I convert a Roman numeral date back to a normal date?
Yes. Switch to "Roman numerals → Date" mode, paste the Roman numeral date (dots, dashes, slashes, or spaces all work as separators), and the tool will validate each part and show you the equivalent calendar date.
Why are there several output formats for the same date?
Different uses call for different punctuation: dots are common for European-style dates, dashes and slashes read well in text, and the stacked three-line layout is popular for tattoos where the day, month, and year sit on separate lines. Having all of them ready to copy saves you from retyping.
Is this tool related to the Number to Roman converter?
Yes, they share the same conversion rules. If you only need to convert a single number (not a full date) to Roman numerals, check out the dedicated Number to Roman converter.
