How can I calculate a date back in time / month f.ex (01.05).
if my date string is 01.01.2010 and i want to calculate total months back to 01.05.2009.
Don't matter what type of date string i have, all dates have to be calculated back to 01.05
I have a list of startdate, where I need to loop all dates and calculate months back to 01.05.
How can I do this?
