Title: Mathematics and the Calendar 

Abstract: Irregularities in the calendar, such as leap years and months of differing lengths, complicate making plans for, say, next month. These irregularities clearly invite mathematical analysis. In the first part of the talk, I will discuss a mechanism based on easy mental arithmetic, which helps cope with these irregularities. The procedure can easily be adapted to work out the day of the week for any date in this century, or in other centuries, for that matter. 

 
In the latter part of the talk, I will talk about the deeper mathematics lying behind some less frequently noticed anomalies related to the calendar. These include the differences between the lengths of the four seasons as well as the fact that the earliest sunrise does not occur on the longest day of the year.
