1D Day

One of the best days ever in the life of a Directioner. On November 23rd, 2013 One Direction had a 7 hour day full of 1D, and called it 1DDay. 1D Day was an interactive livestream to promote One Direction's third album, Midnight Memories and to help 1D fans to get a whole day of awesome! It featured the band participating in games, interviews and live performances.

Go watch 1D Day! It was awesome!!

1D Day by all the love,K💕 March 31, 2019
