Old New Year

Discovering the day of the week upon which a particular date occurred is the focus of this resource, from the Centre for Innovation in Mathematical Teaching. The Julian and Gregorian calendars, amongst others, are discussed and students are provided with an algorithm, which they use to verify the day of their own birth. This is then extended to work out the day of the week for any date in the last or the current century. Designed to demonstrate that mathematics is a lively and relevant subject, this resource will also prompt class discussion and develop mathematical thinking.
