How do we proceed?

Convert, one by one, the numbers that represent the month, the day and the year, to Roman numerals.


Day, 30:

X = 10;

30 = 10 + 10 + 10 = X + X + X = XXX;

» 30 = XXX


Month, June:

June is the sixth (6th) month of the year.

Replace the name of the month with the corresponding number of the month of the year: 6.


I = 1; V = 5;

6 = 5 + 1 = V + I = VI;

» 6 = VI


Year, 8:

I = 1; V = 5;

8 = 5 + 1 + 1 + 1 = V + I + I + I = VIII;

» 8 = VIII

Convert calendar dates, write them in Roman numerals

The set of Roman numerals used for writing calendar dates

  • I = 1 (one); V = 5 (five);

  • X = 10 (ten); L = 50 (fifty);

  • C = 100 (one hundred);

  • D = 500 (five hundred);

  • M = 1,000 (one thousand);

    • For writing dates in the future:

    • (*) V = 5,000 or |V| = 5,000 (five thousand); see below why we prefer: (V) = 5,000.

    • (*) X = 10,000 or |X| = 10,000 (ten thousand); see below why we prefer: (X) = 10,000.

Note 1: (*) These numbers were written either with an overline (a bar above the number) or between two vertical lines (two vertical bars).

Note 2 (*) Instead we prefer to write these larger numerals between brackets "()" since: 1) when compared to the overline - it is more accessible to computer users; 2) when compared to the vertical line - it avoids any confusion between the vertical line "|" and the Roman numeral "I" (one).

  • So, (V) = 5,000 and (X) = 10,000.

Note 3: (*) Romans were not using right from the beginning numbers larger than 3,999, so they initially had no representation for numbers like:

  • 5,000 = (V), 10,000 = (X), 50,000 = (L), 100,000 = (C), 500,000 = (D), or 1,000,000 = (M).

These larger numerals were added later to the system and various different notations were used for them, not necessarily the ones above.

For a long time, the maximum number that could be written using Roman numerals was:

  • MMMCMXCIX = 3,999. .
