It’s About Time!
a public lecture by
Professor Don Kurtz
Jeremiah Horrocks Institute, the University of Central Lancashire, Preston, UK

Newton Lecture Theatre INB0114 in the Isaac Newton building, University of Lincoln
Days, Weeks, Months, Years and more: Hear about Roman Emperors, Zulu Wars, Rider Haggard, Thomas Hardy, the English time riots, and how the days of the week got their names in an amusing and informative tour of the Western calendar. Astronomers have designed calendars in societies through history, but calendar reform in western cultures has been driven by the needs of priests to set important religious holidays. In this talk you will learn how the now-International Gregorian calendar grew out of the earlier Julian Calendar, which was itself a refinement of the Roman Republican calendar. You will also learn why “30 days hath September …”, why the UK tax year starts on the odd date of 6 April, and why the Russian Orthodox Christmas is celebrated on 7 January. The day, month and year are probably not what you think they are, and they no longer govern the GPS time on your phone. Come find out how we measure time’s passage.
