People born in the year MMI (2001) are now 24 years old (which is XXIV in Roman numerals)

How do we write the number 2001 in Roman numerals?

The number 2001 in Roman notation (MMI) elegantly combines the millennium marker MM with the simple unit I, demonstrating how Roman numerals handle the transition beyond round thousands.

Breaking down MMI:

MM = 2000 (M + M = 1000 + 1000)
I = 1 (one)
MMI = 2000 + 1 = 2001

The year 2001 demonstrates Roman numerals' logical progression: starting with the familiar MM (2000) and adding the simple I (1). This creates a clear, readable notation that flows naturally from the millennium base.

Common mistakes with 2001

The main error is confusing the millennium start. While many celebrated in 2000, the 21st century technically began on January 1, 2001. In Roman notation, MMI clearly shows "two thousand and one" - the true millennium start.
