Gary Bastin's Day of the Week Calculator

Ever wonder what day of the week you, or an ancestor, were born, or married? Or, for a particular Civil or Revolutionary War battle, what day of the week it occurred? Well, now it is easy to calculate the day of the week for any of these, provided you know the date. This calculator works within rather wide limits, and is by Gary Bastin. It is uniquely available only on the BASTIN Family Website!
