Also...
From Year 607 BCE to 1 CE is 607 years
From Year 1 CE to 1914 CE is 1913 years
607-1 = 606
(Ooops! Forgot the zero year!)
607 - 1 -1 = 605
1914 - 1 = 1913
1913 + 605 = 2518
CORRECTION:
607 - 607 = 0
1914 - 1 = 1913
1913 + 607 = 2520
There we go, that's better. Now we still have it leading to... 1913.
