    Question Calculate difference between formatted dates in a userform

    Hi everybody!
    I am trying to calculate the difference in days bewteen two dates, formatted as dd/mm/yy, in order to change the font color of the "date due" field to red, 30 days before.
    Please see the attachment... wright a due date and click the button... you will see same weird numbers as results!
    It is only right when the date due and today are the same. It mark zero...
    Why that?

    Re: Calculate difference between formatted dates in a userform

    Well, i got it working on my pc BUT only if i enter the date due like mm/dd/yy.
    Unfortunately around here we use dd/mm/yy... and users will enter dd/mm/yy - so i am still testing... with poor result so far.
    Some more suggestions?

    You don't need CDate(Date). Date is already a Date value, so there is no need for CDate with it.

    If your regional settings are set to use dd/mm/yy then CDate should work as it uses your regional settings. If your regional settings are set to mm/dd/yy then you really ought to change them if you like to use dd/mm/yy.

    If you know for certain that the users will enter the date as dd/mm/yy, you might use DateSerial and Split

    The combination between the two gurus is terrific! I got it to work when users enter the date like dd/mm/yy. I will validate the field just to be sure!
    Thanks a lot to both of you.
    By the way... there is any method to check the users regional settings, so i can make a case for English or European?
