2013 is a special year….


It is the first year to have no repeating digits for a long time.

For example: 1922 has two 2’s. 2005 has two 0’s. 1979 has two 9’s.

When was the last year that had no repeating digits?

  1. I think Daniel is right! Previous years in the 2000s have had a repeating number, and in the 1990’s every year had a repeating number, it’s not until 1987 that it occurs. Well done Daniel.
