That particular series of numbers will not come up ever again. The next time we might have the same number for the month, day, and year would be 13-13-13, but because there is no 13th month, that will not happen. Does that make sense?
Nothing unless you are superstitious. It IS the last time therell be a triple match date like that until next century. 100 years not 1000 but there are only twelve months so there wont be a year to match the month/day until year 3001. 89 years from now. We dont have a 13th month or 14th etc .
