You'd better look at help for the DAY function again. It doesn't give day
of the week, it gives 1 to 31, in other words day of the month.

If you want a number for day of the week, look at help for the WEEKDAY
function.
If you want to display the date in ddd format, just use that format on your
original date, or on a cell which merely copies it, e.g. =F68.
If you want it as text, use =TEXT(F68,"ddd")

Followed the help and used Day function to calculate the day of the week
then
formatted as custom to ddd to show short day name.

But sometimes it returns wrong day. e.g.
09/05/2009 (F68). Formulae G68 is =DAY(F68), returns Mon. Buts its
actually
Sat???

Any ideas
Thanks
