To understand historical dating you need to understand calendar systems, and to understand those you need some basic astronomy. I find it a fascinating and pervasive subject that rewards you with a deeper understanding of the world around you.

As a Scotsman I was quite pleased by the synchronicity of the broadcast date as this also marks the 250th anniversary of the birth of our national poet Robert Burns.
