## Date to Roman Numeral Converter

The tool works by entering the regular date on the left panel and will automatically generate the Roman Numeral date on the right panel. It also works in reverse by changing the value on the right.

Here's how to interpret the actions:

Today is for example October 10th, 2019. Converting this date to Roman Numerals would look like this:

10/10/2019 = X/X/MMMCMXCIX

The "X"s represent the numbers in the date that stay the same in both systems (10/10), and the Roman Numerals represent the numbers that have been converted (2019).

To convert a regular number to a Roman Numeral, the process is relatively simple. There are only seven different symbols used in Roman Numerals, and each symbol represents a specific value.

These are the seven symbols and their respective values:

Numeral | Number |
---|---|

I | 1 |

V | 5 |

X | 10 |

L | 50 |

C | 100 |

D | 500 |

M | 1,000 |

## How to Convert a Number to Roman Numerals

To convert a number to Roman Numerals, you simply need to break the number down into its component parts and then find the corresponding symbols. For example, the number 2019 can be broken down into 2000 + 10 + 9. Therefore, the Roman Numeral equivalent would be MM + X + IX, which is equal to MMXIX.

It's important to note that there are some rules that need to be followed when using Roman Numerals. First, symbols can only be repeated three times in a row. So, while you could technically write IIIII to represent the number 5, it's much more common (and correct) to use the symbol V instead.

Second, certain symbols can only be used if they're followed by another specific symbol. For example, the symbol I can only be subtracted from the symbols V or X. So, while IV could represent the number 4, IIV would be incorrect.

Third, only one subtraction can be made per number. So, while XVI could represent the number 16 (10 + 5 + 1), XIV would be incorrect because it uses two subtractions (10 - 1 + 5).

Finally, the largest symbol should always be used first. So, while MM could represent the number 2000 (1000 + 1000), MMM would be incorrect because it uses three of the same symbols in a row.

## What is the history of Roman Numerals?

Roman numerals are a numeral system originating in ancient Rome and were used throughout the Roman Empire. They were based on the use of the letters of the alphabet, with certain letters representing certain values.
