Many of us are seeing in a new year, but of course there are, even today, several different ways of marking dates and years in various parts of the world. The most popular calendar, though, is the Gregorian, introduced in October 1852 by Pope Gregory XIII.

In this episode of Not Just the Tudors, Professor Suzannah Lipscomb is joined by Dr. Christina Faraday to find out how and why the Gregorian calendar was introduced, the impact it had on people’s lives, and the serious debate and, in some countries, centuries long resistance to its use.

This episode was edited and produced by Rob Weinberg.
