Common mistakes
Wrong: MCMXX1
Is MCMXX1 the same as MCMXXI?
No. MCMXX1 has the digit 1 where the letter I should be, so it isn't a Roman numeral. The year is MCMXXI.
Wrong: MCMXIX
Is MCMXIX also 1921?
No. Swapping the last two letters puts the smaller symbol first, so it subtracts: MCMXIX is 1919.
Wrong: MDCCCCXXI
Why not MDCCCCXXI?
A symbol repeats at most three times in a row. The standard form uses subtraction: MCMXXI.
