2017 is a year in the 21st century.

Events

• Friday, October 27: Emmett Brown arrives from September 7, 1893 in the DeLorean Time Machine, intending to purchase an anniversary present for Clara. Unbeknownst to him, Verne Brown was also present in the vehicle. After his father left the car, Verne was able to explore 2017 Hill Valley. He quickly became lost and was temporarily kidnapped by the remaining members of Griff's gang so that they could take advantage of Halloween and rob a store in disguise. Luckily, Verne was able to stop their plan and reunited with Doc.
