Yes very much so.
It will be as the ancient Romans would have notated it MMLXXXXVIIII = 2099
Presumably you mean what date will have the most Roman numerals in the 21st century? If so then it will be December 31 2088 which will be: XII-XXXI-MMLXXXVIII actually, August 28, 2088 will be the most Roman Numerals in the 21st Century: VIII-XXVIII-MMLXXXVIII
October 21st, 2008 in Roman numerals is XXI.X.MMXVIII.
April 21st, 2008 is written as XXI.IV.MMVIII in Roman numerals.
XXI-VI-MMXII

XXI-VI-MMXII
Xxi, vii, mmxii
XII/XXI/MCMLXXXV
The Roman numeral for 21 is XXI
The date February 21st 2009 can also be written as 02-21-2009 and in Roman numerals this would be II.XXI.MMIX
March XXI MDCCCCLXXX (1980) or March XXI XXMM (2000-20). Note that the Roman numerals for 1980 are not MCMLXXX.
21 July 1966 = 21.6.1966 = XXI.VI.MCMLXVI
In accordance with the modern rules now governing the Roman numerals system it will be the year of 2088 which in Roman numerals is written as MMLXXXVIII that will have the most numerals in it but if we were to write out 2099 in the same way that the ancient Romans once did then that would be even longer but instead we would now consider 2099 to be MMXCIX instead of its real original notation which once was MMLXXXXVIIII and could have been abridged to IMMC.QED
