2.  Enter the month (1-12), day (1-31), and year (4 digit) for the ealier date.

YEAR=?2000

DATE 2
MONTH=?6
DAY=?1
YEAR=?2000

               1

Comment: Consecutive days give dbd=1.  If the dates entered are the same, dbd=0.

Example #2:
DATE 1
MONTH=?4
DAY=?18
YEAR=?1983

DATE 2
MONTH=?12
DAY=?21
YEAR=?1982

DBD=
            -118

Comment: If the dates entered are in the wrong order, the answer will be the negative of the correct answer

Example #3:
DATE 1
MONTH=?2
DAY=?10
YEAR=?95

DATE 2
MONTH=?2
DAY=?12
YEAR=?00

DBD=
          -34697

Comment: Your calculator is not smart to recognize that 00 is supposed to be five years after 95, so it gives a meaningless answer.  This is why you should use four-digit years, like in this next example:

Example #4:
DATE 1
MONTH=?2
DAY=?10
YEAR=?1995

DATE 2
MONTH=?2
DAY=?12
YEAR=?2000

DBD=
            1828
