What's going on with the Day formula for 2010? I am working in Excel 2003
and the formula that I always use to pull the day of the week isn't working.
I thought it might be my spreadsheet but I tried it in a blank one and got
the same thing.

Cell E3 has date 01/28/2010 formatted as a date. Cell G3 references cell E3
with this formula =DAY(E3) and it is formatted as custom DDDD - so that I see
the day of the week. January 28, 2010 is a THursday and it returns a
Saturday. When I format as a date only I get January 28th 1900. What am I
doing wrong. It is not set to 1904 date system (when I do that I get 2014).
