**Riddle**: Something very extraordinary happened on the 6th of May, 1978 at 12:34 a.m. What was it?

The answer of this riddle is so interesting. At that moment,on the 6^{th} of May,1978 at 12:34 a.m., the time and day could be written as: 12:34, 5/6/78. Unless someone alive in 1978 lives to be over a hundred, they won’t be alive when it happens again.

The time and date was 12:34 5/6/78, counting from one to eight. The next time this event will occur is 12:34 6 May 2078. Unless someone alive in 1978 lives to be over a hundred, they won’t be alive when it happens again. Therefore, this is something very extraordinary.

The answer is: At that moment, the time and day could be written as: 12:34, 5/6/78.
