2013 in words: Two thousand thirteen
To write the year 2013 you set the groups largest first: MM (2000) + X (10) + III (3), giving MMXIII. Writing a year is the same procedure as writing any other number, and the century group at the front is the part you can reuse for every other year in the same hundred.
If this is going onto something permanent, set it once and check it back before you commit. A plaque, a cornerstone or a tattoo gives you no second attempt, and the stencil generator on this site renders MMXIII at a size you can hand to an engraver.
What MMXIII means, letter by letter
MMXIII is 2013, "two thousand thirteen". It is built from MM (2000), X (10) and III (3), read from the largest value down and added together. Every symbol here is added in sequence, with no subtraction involved.
To read MMXIII back, scan it left to right, largest value first, adding as you go. The running total lands on 2013:
| Read | Worth | Running total |
|---|---|---|
| MM | 2000 | 2000 |
| X | 10 | 2010 |
| III | 3 | 2013 |
There is no subtraction anywhere in MMXIII, so every letter simply adds to the total: no letter changes the meaning of the one next to it. Read aloud, MMXIII is simply "two thousand thirteen".
Write MMXIII step by step
The rule is always the same: take the largest Roman value that still fits, write its symbol, subtract it, and repeat until nothing is left over. Applied to 2013 that gives 6 steps.
| Step | Take | Write | Numeral so far | Left to write |
|---|---|---|---|---|
| 1 | 1000 | M | M | 1013 |
| 2 | 1000 | M | MM | 13 |
| 3 | 10 | X | MMX | 3 |
| 4 | 1 | I | MMXI | 2 |
| 5 | 1 | I | MMXII | 1 |
| 6 | 1 | I | MMXIII | 0 |
Nothing is left over after step 6, so the finished numeral is MMXIII. Written out in English words that is "Two thousand thirteen".
Forms to avoid when writing 2013
These are the spellings people reach for instead, and why each one is wrong for 2013.
- Not MMXIIII. I already appears three times in MMXIII, which is the maximum. A fourth I is never valid, so if you need more you move up to the next symbol instead.
Check MMXIII reads back as 2013
Writing a numeral and verifying it are two different jobs, and the second one is what saves you on anything permanent. Read MMXIII back left to right, adding each group and treating any smaller-before-larger pair as a single subtraction. If you land on 2013, the numeral is correct. The converter above does exactly this and refuses any non-standard spelling, so a value it accepts is a value you can use.
