WC #16 Christmas Summer Comet and Patreon Plug

A bonus summer episode! Professor (and Sir) Colin Humphreys of Cambridge discusses the evidence putting Christmas in the spring or summer rather than December. And...I plug my new Patreon site where you can get episodes all year round. (And there's a longer version of THIS VERY EPISODE at Patreon.com/weirdchristmas with 45 more minutes of weirdness!)
