In today's terms it is: July XXXI MCMXCIX or as VII-XXXI-MCMXCIX

But the Romans themselves would have probably calculated the number 1999 on an abacus counting device as MDCCCCLXXXXVIIII and simplified it to IMM (-1+2000 = 1999)

Today's rules governing the Roman numeral system were introduced during the Middle Ages but that was centuries after the disappearance of the Roman Empire.
