Convert a date

  • Day · Month · Year

    XXIX · VIII · MMXXVI

    The most common layout outside the US. Reads as day first.

  • Month · Day · Year

    VIII · XXIX · MMXXVI

    The US convention. Identical characters to the layout above when both numbers are under 13 — decide which you mean before you commit.

  • Dashes

    XXIX - VIII - MMXXVI

    Reads cleanly at small sizes and on curved placements like a wrist or collarbone.

  • Slashes

    XXIX / VIII / MMXXVI

    Unmistakably a date, which removes the day-versus-month ambiguity for most readers.

  • Stacked

    XXIX VIII MMXXVI

    Three lines. Suits a spine, a forearm running lengthways, or a narrow vertical space.

  • Year only

    MMXXVI

    Shortest and least ambiguous. Often the better choice when the year is what matters.

That date runs to 20 characters on its longest line. It may not stay legible on a small placement like a finger or a wrist — ask your artist about the minimum size, or consider the year-only layout.

Before you commit to a date tattoo

Decide day-first or month-first before you book

XI · IV · MMXX is 11 April to most of the world and 4 November in the United States. Both are correct, and nothing in the numerals tells a reader which you meant. If the date could be misread either way, use slashes, spell the month, or accept that some people will read it the other way round.

Long numerals do not shrink well

Years in the 1870s and 1880s produce strings like MDCCCLXXXVIII. On a wrist or a finger those characters run together as they age and the ink spreads. Ask your artist about the smallest size that will still read in ten years, and consider the year-only layout if the full date will not fit.

Check the numerals twice, then once more

A date tattoo with a wrong numeral is a permanent typo, and it is the single most common regret with this style. Copy the result here, have someone else read it back to you against the actual date, and check it again on the stencil before the needle starts.

Serifs help more than they look like they should

A serif face separates I from a stray line and makes repeated characters like XXX easier to count. Sans-serif looks cleaner on screen and gets harder to read on skin over time. Most artists will steer you toward a serif for numerals, and it is worth listening.

Common questions

How do I write my birthday in Roman numerals?

Convert each part separately — day, month and year — then join them with a separator. Enter the date above and every sensible layout is generated for you. The parts are never merged into one number; a date is three numerals, not one.

Why is there no zero in Roman numerals?

The Roman system had no symbol for zero, so a date part is always written as its own value. There is no leading zero on a single-digit day or month: the 5th is V, never 0V.

What separator should I use between the numbers?

Dots and dashes are the most common and read well at small sizes. Slashes make it unmistakably a date, which removes day-versus-month ambiguity. Stacking the three parts on separate lines suits a spine or a lengthways forearm piece.

Should the numerals go on a wrist, forearm or ribs?

A short date works almost anywhere. A long one needs length rather than width, so a forearm running lengthways, a collarbone or a spine handles it better than a wrist. Long strings on fingers rarely age well.

Is IIII or IV correct for four?

IV is standard and is what this tool produces. IIII appears on clock faces by convention and reads as a mistake to almost everyone else, so it is not a good choice for something permanent.
