How to Convert Normal date to Roman Date

If you do not have an in-depth knowledge of roman numerals, then converting a regular date to an ancient date can prove to be a complicated task for you as there is a particular process when it comes to converting dates.

Since the dates involve month names, these can't directly be converted into numbers, and there are exclusive abbreviations used to call out the months. Romans did not have the same set of alphabets that we use today. Therefore their month names differ in what we use nowadays.

Converting the Day of the Date

Convert the number of the day of the date into Roman numerals by using lower case letters. These lower case letters were an invention of medieval scribes as Romans did not have lower case letters - and became popular with the advancement and printing in the 15th century. One possible reason for using lower cases as the day number can be to separate date and year numbers and make it look more formal or presentable. Some examples are 1 is written as i, 2 is written as ii, 3 is written as iii, 4 is written as iv, 5 is written as v, 10 is written as x.

After 10, you need to add or subtract to form dates. E.g., write i after x to write xi, which denotes 11, and this process goes on further.

Points to remember

1. You can add the same number thrice by writing it on the right side of the preceding figure.

2. Only one number can be subtracted, and the number to be subtracted is written on the left side.

Converting the Month of the Date

Roman names for months were much the same as ours; the only difference was they did not have U and J in their alphabet set. Their list of months is:


For user convenience, these months were abbreviated by the Romans, and the initial three letters can be used to denote a month along with a period. The only exceptions are MART. and SEPT., where the initial four letters are used instead of three. It doesn't matter if you choose to write JUL. instead of IVL.

Converting the Year of the Date

The basic symbols used in roman numbers are I, V, X, L, C, D, and M, which stands for 1, 5, 10, 50, 100, 500, and 1,000, respectively. These are used to form thousands of numerals. To write years, these symbols are used. For e.g., if we want to write 1996, we would write MCMXCVI where MCM denotes 1900, XC is 90, and VI is 6.


Using the above method, the normal date is converted to a roman date. Since different countries follow different formats for dates such as the UK, Europe uses dd/mm/yyyy while countries like North America use mm/dd/yyyy and other countries like Japan use yyyy/mm/dd. Some examples of different date formats are:
