Talk:21st century

Series 7 Part 1

 * In The Doctor, the Widow and the Wardrobe, Amy and Rory say it has been 2 years since the Doctor dropped them off, suggesting it is now Christmas Day 2012 in modern day, as the Doctor left them in Summer 2011,meaning he has been gone a year and a half - two Christmases - they would say "two years."
 * Pond Life then follows Amy and Rory from April to August 2013, with Asylum of the Daleks starting on the 1st September 2013 (its airing date +1 years). Dinosaurs on a Spaceship and A Town Called Mercy then take place over the next few months of Amy and Rory's life.
 * The Power of Three and the Slow Invasion then occurs from the 25th July 2014 to the 22nd July 2015, and the Angels Take Manhattan a few days later.

Series 7 Part 2

 * We know in episodes 6-13 Clara lives in 2013, meaning the modern day things take place around the time that Pond Life is happening concurrently.
 * It takes about a year and a half to train to become a teacher, and we know that The Day of the Doctor has to take place after the Power of Three in the modern day timeline for Kate Stewart, so it has to be that The Day of the Doctor then takes place around November 23rd 2015 (airing date +2 years), which would be enough time for Clara to quit being a nanny and become a teacher, and her and the Doctor to go on lots more weekly adventures to become as experienced as they seem at the beginning of The Day of the Doctor, and would also work as Kate would already know the Doctor by then. The Time of the Doctor takes place on Christmas Day 2015.

Series 8

 * In Deep Breath, they arrive back in Glasgow a couple of days later in late 2015. 3 weeks later, Danny starts work at Coal Hill, in mid-January 2016. The rest of the season takes place over those next few months.
 * Steven Moffat said Last Christmas is "about 6 months" after Death in Heaven, and in Last Christmas, Clara says they should help each other with a Christmas cracker "every Christmas", suggesting this is only one Christmas later. This would mean Dark Water/Death in Heaven occur at the end of term around July, and In the Forest of the Night around late June, which is also suggested by the weather, and the fact that schools tend to go on trips around late June/early July.
 * A late June/early July 2016 In the Forest of the Night date then fits with what the Doctor says about a tree growing until 2016.

Series 9
BEJT ☎  01:24, November 2, 2015 (UTC)
 * I would say series 9 all happens on their airing dates + 2 years (September-December 2017). This would also fit with the statement in The Zygon Invasion that it has been two years since The Day of the Doctor, as it would be late October/early November 2017 - two years after November 2015.
