Bug in Excel

I'm trying to test dates in Excel to see if they're before the end of 2007,
so I tried
A1<=12/31/2007 and it returns FALSE even when the date in A1 is before
12/31/2007.

So I put the date 12/31/2007 in a separate cell, D1, and the formula =A1<=D1
returns TRUE, as it should.

What gives? Is there something magical about entering the date 12/31/2007
inside the formula compared to in a separate cell?

Nope. Try any other date, you'll probably see same results.

Try the formula =(A1 <= DATEVALUE("12/31/2007"))
so that you're actually comparing apples to apples.
