Abstract

The continuous calendar enables the user to read the day of the week corresponding to any date, and the date of Easter, both past and future. It consists of a fixed rule bearing dates for 99 future and past years on one side, and the dates of Easter corresponding to the Dominical year on the other. One side of the cursor is used to read the day of the week and the other the date of Easter. Corrections for Gregorian and pre 1583 calendars are provided.
