How Saturday will be the last sequential calendar date for 20 years Saturday Dec 13,2014

It's rare. It's orderly. And when it comes to remembering an anniversary date, it's as easy as 12/13/14.

Saturday's December 13, 2014, represents the last sequential calendar date for at least 20 years (Jan. 2, 2034) and another 89 years if waiting for Jan. 2, 2103.

If a person has a heart set on commemorating the next 12/13/14, make sure that heart can stand another 100 years on earth to make it to Dec. 13, 2114.

For cryogenic fans, it's 1,000 years until 3014.
