WEEKDAY()

Regarding WEEKDAY(), I read that problems can occur if dates are entered as text.

Based on this, it is understandable that =WEEKDAY(2/14/2008) returns a wrong result (7). This is because general format is same as text.

If I enter =WEEKDAY(DATE(2008,2,14)), I get the correct result (5).

Okay, so far. What I don't understand is the following.

I click A1 and key in 2/14/2008, then in A2, I key in =WEEKDAY(A1). I also get the correct result (5).

The way I enter 2/14/2008 to A1 is exactly the same as I enter 2/14/2008 *directly* to the formula. It amazes me that referencing A1 in WEEKDAY() gives me the correct answer whereas keying it in as part of the formula won't work.

Comments welcome.
