I was thinking about the relationship between 9-1-1 and 1-1-2, the alternate dialing codes for emergency. From September 11, to January 12 is a 123-days later, from September 11 to February 11, which can also be written 11/2, is 153-days. February 11 is the 42nd day of the year. 42 is often paired with 153 in this coding practice.
What do you think? Coincidence?
