Your question is kind of vague. If there is a variable that you want to have that date for test purposes, you would need to Break your program (assuming it did not issue a Break on its own due to an error) and then set that variable equal to that date, and then try continuing your program. For example, if your program is in Break mode and you want to set MyDate equal to 1/22/2012, you could do it either this way...

MyDate = DateSerial(2012,1,22)

or this way...

MyDate = CDate("1/22/2012")
