Date to Roman Numerals Converter

Split the date into day, month, and year, convert each part separately using the standard Roman symbols (I=1, V=5, X=10, L=50, C=100, D=500, M=1000), then join them in your chosen order. For example, October 7, 2026 becomes VII.X.MMXXVI: day 7 = VII, month 10 = X, year 2026 = MMXXVI.

Press the Today button in the converter above for the live value. As a fixed reference, October 7, 2026 in day-month-year order is VII.X.MMXXVI.

Both are correct as long as the order is clear to your reader. Day-month-year (VII.X.MMXXVI) is standard in most of the world; month-day-year (X.VII.MMXXVI) is common in the US. The converter above supports DMY, MDY, and YMD — pick one and stay consistent, especially for tattoos and engravings where ambiguity is permanent.

A date is not one number — it is three structured values (day, month, year). Converting 7/10/2026 as the single number 7102026 would give nonsense; converting each part separately keeps the date readable and unambiguous. Every correct converter works this way.

Standard Roman convention never repeats a symbol more than three times in a row, so 4 is written subtractively as IV (5 minus 1). The same rule gives IX for 9, XL for 40, XC for 90, CD for 400, and CM for 900. Some clock faces use IIII for visual balance, but IV is the correct standard form.

With the standard seven symbols the largest is 3999, written MMMCMXCIX. This converter also supports years 4000 to 9999 using vinculum notation — an overline multiplies a symbol by 1,000, so 4000 is written as IV with an overline (5000 minus 1000). Note that not every reader recognises the overline, so years above 3999 are best avoided in designs.

Enter the date in the converter, choose your order and separator, and double-check the result with the Decode tab before it becomes permanent — a typo in Roman numerals is forever. Dots (VII.X.MMXXVI) are the most common style for tattoos; also decide upfront whether you want month-day-year or day-month-year.

Yes — use the Latin month-name option in the converter. January 14, 2010 becomes XIV.JANUARIUS.MMX, or in the classical spelling used by the Romans themselves (no J or U): XIV.IANVARIVS.MMX.

Paste it into the Decode tab above and select the order it was written in. The decoder validates each part by re-encoding it, so malformed numerals like IIII or VV are rejected instead of silently misread. Two-digit years are read as 20xx — the page states this openly because 02 alone is genuinely ambiguous.

With a real date in A1 and day-month-year order: =ROMAN(DAY(A1))&"."&ROMAN(MONTH(A1))&"."&ROMAN(YEAR(A1)). Excel's ROMAN function only handles 1-3999, which is fine for days and months and covers all practical years. Change "." to your preferred separator.

Any of them — the meaning is identical. Dots (VII.X.MMXXVI) are the classic choice for tattoos and inscriptions; dashes and slashes suit documents; spaces look clean in invitations. The converter lets you preview all five styles before you commit.

In day-month-year order it is October 7, 2026: VII = 7 (the day), X = 10 (October), MMXXVI = 2026 (the year). Paste any Roman-numeral date into the Decode tab to read dates like this instantly.

No. Every conversion runs locally in your browser in JavaScript — nothing is uploaded, stored, or tracked, and the page works offline once loaded. That is why the Decode tab can safely validate a private date like a birthday.

A Roman numeral converter translates a single number (for example, 2026 becomes MMXXVI). This tool is date-specific: it validates that the date is real (rejecting February 30, for instance), converts day, month, and year as three separate parts, supports Latin month names and short years, and decodes Roman dates back. For single numbers, use our Roman numeral converter instead.
