years and 1 month. What we want to have happend is excel to stop the
rounding and add the months like months with a base of 12 not 10. We have
tried, int, rounding, changing formats, precise formatting...and are at a
loss.

Please help in despartate need.

Hi Judy,

There is no simple reliable way to add dates like that.
Use Excel's built-in date facilities instead.
To learn all about calculating with dates, look he

Not entirely true.

With the date in A1 and the "time" to be added in B1:

=DATE(YEAR(A1)+INT(B1),MONTH(A1)+MOD(B1,1)*10,DAY( A1))

Nevertheless, do read the article I pointed you to.

Hi Judy,

As Niek says you are probably better off sticking with Excel's
built-in date facilities but for what it is worth the following formula
will convert your decimal input to the decimal equivalent on a
basis of 12 instead of ten.

=INT(A1)+((A1-INT(A1))*10)/12
