Experts,

I have a column in a table with a datea  stored as 05/01/2013
                                                                                     06/01/2013   etc.

I would like to compare the calculated date:

Dateb = date() - weekday(date()) + 1;   which is SAS format 19511

Is there a way to compare these two dates?

Dates in SAS is stored as a number field but can be formatted to be displayed in almost any possible combination e.g. MM/DD/YYYY, DD/MM/YYYY etc so even if it's showing as a nice looking human readable date, what's underlying is still a number offset from 01 Jan 1960..

therefore:
if DateA is already a date field, you can compare directly i.e. if DateA = DateB then

if DateA is not already a date field but a character field, you can use the input function to convert the character date to it's numerical equivalent i.e. input(DateA, MMDDYY10.) assuming the date string is in MM/DD/YYYY format, or input(DateA, DDMMYY10.) if the date string is in DD/MM/YYYY format before comparing to DateB as above
