Official BBC publication Who-ology (also known as Doctor Who: The Official Miscellany) states that it would take 38 hours, 11 minutes and 18 seconds to watch all Tenth Doctor episodes. The book was written by Cavan Scott and Mark Wright and published in 2013.

Whographica, another publication by BBC Books, claims it would take 1 day, 14 hours, 11 minutes and 8 seconds to watch every Tenth Doctor episode starting with "The Christmas Invasion" and finishing with the second and final part of "The End of Time". This does not appear to take "The Day of the Doctor" into account, an episode which heavily features Tennant's Doctor.
