So long to the repeating day/month/year's:

01/01/2001
02/02/2002
03/03/2003
04/04/2004
05/05/2005
06/06/2006
07/07/2007
08/08/2008
09/09/2009
10/10/2010
11/11/2011
12/12/2012

Won't happen again until 01/01/2101, and there won't be another time with only two different digits until:

03/03/3003
last time was 02/02/2002

See you in 3003!
