Calender Dating

The calender dating is a method of numbering the days of the week and the week of the month. This unique numbering is done so that specific days or specific weeks of the month can easily be called for doing additional time specific analytics. 

The following picture shows the methodology the number the trading days of the month. One method uses a consecutive numbering method and the other uses the week and day method.
