Assuming you write your dates like an animal.
Discussion
I used to use this date format until I realized it's not really well designed for universal or permanent use since it counts years with a fictional birth as an approximate 0 mark
Now I prefer to count years from a meaningful point in time, like the UNIX epoch
Today's date with UNIX years is 055-05-20
The 2013-02-27 example becomes 043-02-27
