help with date formula please.

[julief]

I am trying to compare two lots of data. Once piece of data is coming from a
database which is holding the date field in format dd mm yyyy hh:mm. The
other piece of data is in standard ddmmyy format. I need to compare the two
dates to make sure they are the same.
The problem i am having is that because one piece of date holds time data
also it is not showing as being the same date even though it actually is.
Can anyone please give me a formula which strips out the time element and
will then compare. I have tried to use the day() month() year () function
but with no luck.

I suppose the date from the database is in text format:

=LEFT(SUBSTITUTE(B1," ",""),4)&MID(B1,9,2)

converts it to ddmmyy text

Excel stores dates as numbers with Jan 1, 1900 equaling 1 and each date
afterwards is incremented by 1. Hours are equal to 1/24 and each minute
equals 1/(24 * 60). A datte with no hours and minutes is equal to a whole
number like 37524 and one with 8 hours (8/24) equals 37524.333333333. To
compare the two numbers you simply need to use the INT function to round the
number to a whole number

37524 = Int(37524.333333333)

Assuming that neither of the fields is text, and that they are Excel numbers
formatted as date and time, =INT(A2)=B2 is a suitable test.
=INT(A2) gives you date without time.

If you are starting with text, you ought to convert to Excel date & time,
then work from there.
