The first cool date of the year is coming up on Thursday – 1/8/15 is a sequence of 7’s:

1 + 7 = 8;  8 + 7 = 15   OR

15 – 8 = 8 – 1 = 7

A sequence of one’s we recognize easily; you probably heard that 12/13/14 was the last “one” of those until next century. Take heart, there are more than thirty years of various sequences upcoming before we run out this century!
