Note that the maximum year number that you can convert in our Roman numeral converter is 3999. The specificity of Roman numerals themselves explains this peculiarity. For a long time it was simply impossible to write a number greater than 3999 in Roman numerals.

Over time, this problem was solved rather elegantly and unusually. When recording larger numbers, they began to put a bar above the value of the number. This meant that the value of the letter was multiplied by 1000.

That is, 4000 could be written as I̅V̅. This system is called vinculum from the Latin “chain, tie” and it was introduced by a Dutch mathematician Franciscus van Schooten in XVII century.

Living in the twenty-first century, you are not likely to calculate dates for the year 4000 in this Roman numeral converter. Although, of course, it would be nice to occasionally peek into such a distant future just out of curiosity.

The History of Roman Numerals

The first uses of the symbols known as Roman numerals began to appear between 900 and 800 B.C. Several hypotheses explain how Etruscan and Roman numerals were created. According to one hypothesis, the prototypes of Roman numerals were shepherd's counting sticks. Shepherds carved notches on their sticks. So "I" became a unit with notches every five units (or V) and cross notches every ten units (X).

According to another version, the prototypes were hand signals. Thus, I, II, III, and IIII denoted individual fingers, and V denoted all the fingers together. Numbers from 6 to 9 symbolized the display of digit V with one hand and simultaneously digits I, II, III or IIII with the other, and 10 (X) denoted crossed thumbs.

More confidently we can trace the origin of Roman numerals to the Roman Republic, which existed from 509 B.C. to 27 B.C. At that time the Romans were already using a system of letters and symbols to represent numbers. This system was not yet the Roman numeral system as we know it today. It was a system of counting signs used to keep track of quantities, such as livestock or money owed.

Over time, these counting signs evolved into a more sophisticated system of letters and symbols that could represent large numbers. Over time, the Romans created the system of numerals that we know today. It used the seven letters I, V, X, L, C, D, and M to represent the numbers 1, 5, 10, 50, 100, 500, and 1,000, respectively.

Numerals are joined together to represent a number. For example, the number II represents the number 2, and the number XX represents the number 20.

The Roman numeral system is unique. It does not use the zero symbol and does not use numeral positions to represent units, tens, hundreds, thousands, and so on, as the Arabic system does.

The Romans used numbers for many things, such as inscriptions on monuments and the numbering of pages and chapters in books. Inscriptions on public buildings, statues, and monuments were among the most common uses of Roman numerals.

The Romans also used them to mark numbers on coins, military equipment, and other items. Roman numerals were also used in everyday life, such as counting and trading. This contributed to the spread of the system outside of the empire.

After the fall of the Roman Empire, people continued to use Roman numerals throughout the Middle Ages and into the Renaissance. The Catholic Church was one of the most famous institutions to use Roman numerals. The church used the Roman numeral system for many things, such as numbering the Pope's reign, chapters of the Bible, and the liturgical calendar.

Roman numerals continued to appear in literature during the Middle Ages and the Renaissance. Roman numerals continued to denote the order of the reign of monarchs. To this day ruling dynasties use this tradition. Not so long ago the British Queen Elizabeth II was succeeded by her son Charles III.

Modern Use of Roman Numerals

Although Roman numerals have a long and rich history, their use in modern society is limited compared to their widespread use in the past. Today, most people use the Arabic numeral system.

Even though Roman numerals are not as common as they used to be, we still use them. Here are some of the places and instances where we see Roman numerals most often:

Ages: We usually write down century numbers using the Roman numbering system. And even though some people may have difficulty quickly identifying which century is indicated by the combination XIV or XVIII, the combinations XX (twentieth century) and XXI (twenty-first century) often appear in front of our eyes and are easy for us to recognize, even if we are not proficient in Roman numerals.

Watch faces: Many traditional and antique watches use Roman numerals to indicate the hours. This gives the watch a classic and elegant look. Even in electronic wristwatch design themes, some lovers of the Roman aesthetic sometimes choose to display the numerals in the Roman system.

Book chapters: Roman numerals are often used to represent the chapters of books, especially historical books. This makes them more elegant and sophisticated.

Movie titles: Roman numerals are often used for titles of sequels to the same movie.

Monuments and memorials: Roman numerals can be used to indicate the years or dates of historical events on historical monuments.

Science: In the field of astronautics, the United States has created several models of rockets, which were marked with Roman numerals. For example, Titan I, Titan II, Titan III, Saturn I and Saturn V. The satellites of the planets, called "moons," in astronomy are usually designated by a Roman numeral added to the name of the planet. In chemistry, the periods of the periodic table are often designated by Roman numerals.

Law: Roman numerals are often included in the alphanumeric lettering of legal codes.

Architecture, design and art: Roman numerals give a piece of work elegance and sophistication and emphasize its connection to cultural traditions.

Tattoos: For some people tattoos depicting specific commemorative dates with Roman numerals look more elegant and refined.

Roman numerals remain an integral part of our cultural heritage, despite their limited use in everyday life. They remind us of the rich history and culture of the Roman Empire. We still use them, giving our works and objects of use a sense of historical value and sophistication.

Converting Dates on Your Own

To understand how an Arabic-to-Roman and Roman-to-Arabic date converter works, you need to know how Roman numerals are formed. Let's take a quick look at the essential rules.

Roman numerals use a combination of letters from the alphabet to represent numbers. Letters I, V, X, L, C, D, and M represent the numbers 1, 5, 10, 50, 100, 500, and 1,000.

Roman numerals have several rules for forming numbers. One of these rules is the addition and subtraction number system. A smaller number must be placed before a larger number to indicate subtraction.

So IX means that 1 was subtracted from 10, and we've got 9.

And XI indicates that 1 was added to 10, which resulted in 11.

Roman numerals are not used to represent zero. They only represent positive integers.

V, L, D digits can't repeat in a row. I, X, C, M digits can repeat but not more than three times in a row. A repetition of the same digit more than 3 times is prohibited. That's why number 4 is written in contemporary Latin notation as IV (as 5 – 1) and not as IIII (1 + 1 + 1 + 1).

Now that you understand the basics of Roman numerals, it's time to learn how to translate dates into them. You can break down the process of converting Arabic dates to Roman dates into a few simple steps:

  • Convert from right to left. Start with the smallest numbers and work your way up to the largest numbers.
  • Start with units: convert the units in the date to Roman numerals. For example, "4" would be "IV." Write "IV" on the right.
  • Move on to tens: Convert the tens in the date to a Roman numeral. For example, "30" would be "XXX." Add "XXX" to the left of the units.
  • Repeat these steps for hundreds and thousands. Write the Roman numeral for hundreds to the left of the tens. And the numeral representing thousands to the left of hundreds.
  • Roman numerals do not have separate symbols for year, month, and day. Therefore, you should specify the date in the format "day-month-year" or "month-day-year.

Here are some examples of how to translate various dates into Roman numerals:

January 1, 2020 = "I-I-MMXX" June 17, 2023 = "XVII-VI-MMXXIII" December 25, 2021 = "XXV-XII-MMXXI"
