- "Sunday, November 13, 1955!"
- —Emmett Brown
November 13 is the 317th day of the year.
- 1955, Sunday:
- Howdy Doody airs as the first show of the morning broadcast.
- Emmett Brown wakes up and records his recollection of the events of November 12.
- Marty McFly wakes up and scares Doc senseless as he was supposed to be in the future.
- Marty shows Doc the letter he received from the 1985 Doc and they read it.
- The weather was rainy, most likely a spillover from the lightning storm that happened the previous night.
