I don't know how to do that, but a work around for the
header is to insert a line at the top of your worksheet
and enter the date or a date formula (like Now())in the
location you want the date to print (left, center, or
right). Then, on Page Setup, on the Sheet tab, tell it to
repeat rows 1:1 on each page. To separate this "date
header" from the rest of the text, insert an additional
blank row and tell Page Setup to repeat rows 1:2 on each
page.
