The measurement of time has always been a facet of Astronomy. The phases in the development of the Gregorian calendar most (but not all!) of us use today make a fascinating story which blends science, history, sociology, religion and psychology.

We conclude by looking at some of the implications of modern physics for the nature of time itself.

About Steve Tonkin

I am a Fellow of the Royal Astronomical Society and have authored many articles and several books on practical aspects of astronomy. I taught astronomy to adults and children for more than 40 years. I am the Dark Skies Advisor to both the Federation of Astronomical Societies and the International Dark Sky Reserve on the Cranborne Chase National Landscape, and split my time between these and doing astronomical outreach. As well as astronomical societies in Britain and abroad, I frequently speak to Rotary and Probus clubs, U3A groups, and schools/youth organisations. I have a monthly column in BBC Sky at Night Magazine, for which I also write equipment and book reviews.

I can deliver talks remotely over Zoom, Webex or MS Teams.
