Because of the way dates are stored in Access, you can just subtract the earlier date from the later date to get the exact number of days. Each day equals 1 and partial days are percents. For instance 6:00 am adds .25 (1/4 of day).
I prefer to use the built-in date functions. In this case, try:
DateDiff("d",[BeginningDate], [EndingDate])
