While many fans developed intricate theories as to the significance of Jess and Dean sharing a birthday, Eric Kripke has stated that he chose the date because it is his wife's birthday.
- Sam Winchester (1983)
In a bizarre coincidence, Eric Kripke's son was also born on this date in 2007.
- Adam Milligan(1990)
This day is also the traditional day for Michaelmas, the feast of Saint Michael the Archangel, for whom Adam eventually served as a vessel.
Sam Winchester is six months old on this day.
