The number 209 is very important in The Overnightscape universe. Frank explained when he first noticed it on episode “1215: Glow Ron”:

My first day in college, the 209 thing happened! September first, second, third or forth, of 1985

Wait a minute. I was born on the 27th of March, 1986.

$ irb
irb(main):001:0> require 'time'
irb(main):002:0> birthday = Date.parse("1986/03/27")
irb(main):003:0> frank = Date.parse("1985/09/01")
irb(main):003:0> puts birthday.mjd - frank.mjd
==> 207

That’s not 209, but it’s pretty damned close.
