A brief History of the Calendar and Time Keeping

Tuesday 23 February, 20h00 • Aula Minderbroedersberg 4-6 • Dr. Donna Carroll, Lecturer of Physics, Maastricht University How many times a day do you check your calendar or look at your clock? These days our lives are driven by deadlines, schedules and timetables. Time and its many divisions (hours, days, weeks, months, and years) have completely shaped our lives and yet we seldom take the time to consider how these concepts arose. The calendar is inextricably linked to the mechanics of our solar system, and the way in which we describe our periods of time has arisen from ancient speculation in astronomy, mathematics and religion. In this talk, Donna Carroll will provide a brief history of our calendar and an introduction to time measurement. A fascinating field where astronomy, astrology, mathematics, politics, agriculture, superstition and religion all come together.
