Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers in this system are represented by combinations of letters from the Latin alphabet. Modern usage employs seven symbols, each with a fixed integer value: . The use of Roman numerals continued long after the decline of the Roman Empire. From the 14th century on, Roman numerals began to be replaced in most contexts by the more sophisticated Arabic numerals ; however, this process was gradual, and the use of Roman numerals persists in some minor applications to this day.
One place they are often seen is on clock faces. For instance, on the clock of Big Ben designed inthe hours from 1 to 12 are written as:. The notations IV and IX can be read as "one less than five" 4 and "one less than ten" 9although there is a tradition favouring representation of "4" as " IIII " on Roman numeral clocks. Other common uses include year numbers on monuments and buildings and copyright dates on the title screens of movies and television programs.
For the years of this century, MM indicates The current year is MMXX Roman numerals are essentially a decimal or "base 10" number system, but instead of place value notation in which 'place-keeping' zeros enable a digit to represent different powers of ten it uses a set of symbols with fixed values. Combinations of these fixed symbols correspond to the digits of Arabic numerals. This structure allows for significant flexibility in notation, and many variant forms are attested.
In fact, there has never been an officially "binding", or universally accepted standard for Roman numerals. Usage in ancient Rome varied greatly and became thoroughly chaotic in medieval times. Even the post-renaissance restoration of a largely "classical" notation has failed to produce total consistency: variant forms are even defended by some modern writers as offering improved "flexibility". Copyright law where an "incorrect" or ambiguous numeral may invalidate a copyright claim, or affect the termination date of the copyright period  it is desirable to strictly follow the usual modern standardized orthography.
The following convention resolves the ambiguities and inconsistencies inherent in Roman numerals by permitting only one permutation for any given value: it is at least widely recognized and adhered to. This table of digits and their equivalents is a convenient representation of this convention: . A number containing several decimal digits is built by appending the Roman numeral equivalent for each, from highest to lowest, as in the following examples:.
Years & Birth Date in Roman Numerals
Any missing place represented by a zero in the place-value equivalent is omitted, as in Latin and English speech:. Roman numerals for large numbers are nowadays seen mainly in the form of year numbers, as in these examples:. Since the largest Roman numeral likely to be required today is MMXX the current year any pressing need for larger Roman numerals is hypothetical.
Prior to the introduction of Arabic numerals in the West, ancient and medieval users of the system used various means to write larger numbers, two of which are described below, under "Large numbers". Neither of these has been standardised for modern use: so that they cannot be described as part of the "usual modern standardized orthography".
The two conventions could be mixed in the same document or inscription, even in the same numeral. Modern clock faces that use Roman numerals still usually employ IIII for four o'clock but IX for nine o'clock, a practice that goes back to very early clocks such as the Wells Cathedral clock of the late 14th century.
Several monumental inscriptions created in the early 20th century use variant forms for "" usually written MCM. It is a common belief that any smaller digit placed earlier than a larger digit is subtracted from the total, and that by clever choices a Roman numeral can be "compressed.
There are multiple examples of IIX being used for 8. There does not seem to be a linguistic explanation for this use, although it is one stroke shorter than VIII.Convert a date into Roman numerals. Enter month, day and year to translate your date into Roman numerals.
