The date 09-05-2009 would be IX.V.MMIX
The date 05-06-09 would be written as V.VI.IX and the date 05-06-2009 would be V.VI.MMIX
IX V MCMLXXXVII
The date 9-9-09 in Roman numerals is IX.IX.IX. If the numbers represent the date 09-09-2009 that would be IX.IX.MMIX
If you write September 09 2009 as 09-09-2009 then you can write using these numerals IX (9) and MM = 2000, so 09-09-2009 becomes IX.IX.MMIX
The date September 23rd 2009 can also be written as 09-23-2009 and this can be represented by the Roman numerals IX.XXIII.MMIX
The date 05-06-09 would be written as V.VI.IX and the date 05-06-2009 would be V.VI.MMIX
IX V MCMLXXXVII
The date 9-9-09 in Roman numerals is IX.IX.IX. If the numbers represent the date 09-09-2009 that would be IX.IX.MMIX
If you write September 09 2009 as 09-09-2009 then you can write using these numerals IX (9) and MM = 2000, so 09-09-2009 becomes IX.IX.MMIX
The date September 23rd 2009 can also be written as 09-23-2009 and this can be represented by the Roman numerals IX.XXIII.MMIX
Nowadays: IX-V-MMIV
V-IX-MMX
II-IX-MMIX
ii-ix-mmix
09 or just plain '9' is 'IX'. 1 = I 2 = II 3 = III 4 = IV ( or IIII) 5 = V 6 = VI 7 = VII 8 =VIII 9 = IX 10 = X 11 = XI 12 = XII As found on the dials(faces) of Classical Clocks. NB In Roman Numerals , the highest value letter is ALWAYS to the left. Except when a lower value letter is placed to the left of a higher value letter, then subtract. Hence X = 10 XI = 10 + 1 = 11 IX = 10 - 1 = 9 Similarly for all other letters.
As you asked this question on 15th September 2009, which can also be written as 15-09-2009, this date in Roman numerals would be XV.IX.MMIX
In today's terms it is: IX-IV-MMIX
