How can I get previous Calendar days of the week.

[RickB75]

I'm working on a timesheet script for myself. It will build a timesheet for me twice a month. I know how to use macros and get the current dates. I'm trying to figure out how to get the days of the week for each date. 

Example: If the 5th of the month was on a Tuesday, how can I tell the script to get that particular day of the week if I'm running the script on 20th of the month??

I was thinking about having the script to write the date and day to a text file each day and on the 16th and 1st of each month read the txt file and build the data that way. I wasn't sure if you guys could recommend a simpler way in stead of having to write a seperate txt file. 

Just curious....

#include <Date.au3>
_DateToDayOfWeek ( $iYear, $iMonth, $iDay )

?
