However, there are rules and guidelines for converting regular numerical dates (in the Gregorian calendar) into Roman numerals. Here’s a general guide on how to convert regular dates to Roman numeral dates:

    1. Assign Roman Numerals to Each Component:
      • Assign Roman numerals to each component of the date: day, month, and year.

      • For example, if the year is 2024, it can be represented as “MMXXIV.”
    3. Write the Month:
      • Convert the month component to Roman numerals.
      • For example, if the month is January (1), it is represented as “I.”
    4. Write the Day:
      • Convert the day component to Roman numerals.
      • For example, if the day is the 1st, it is represented as “I.”
    5. Combine the Components:
      • Combine the Roman numeral representations of the year, month, and day, separated by dots (.) or other appropriate separators.
