Based on the work of fellow Word MVP 'macropod'
www.wopr.com/cgi-bin/w3t/showthreaded.pl?Number=249902 , the following field
in the header will do that - better to download the sample document and copy
the field then edit the delay and final switch rather than try to
reconstruct it ;)

{QUOTE{SET Delay{ = { Page }-1 }}{SET a{=INT((14-{DATE \@ M})/12)}}{SET
b{={DATE \@ yyyy}+4800-a}}{SET c{={DATE \@ M}+12*a-3}}{SET d{DATE \@ d}}{SET
jd{=d+INT((153*c+2)/5)+365*b+INT(b/4)-INT(b/100)+INT(b/400)-32045+Delay}}{SET
e{=INT((4*(jd+32044)+3)/146097)}}{SET f{=jd+32044-INT(146097*e/4)}}{SET
g{=INT((4*f+3)/1461)}}{SET h{=f-INT(1461*g/4)}}{SET
i{=INT((5*h+2)/153)}}{SET dd{=h-INT((153*i+2)/5)+1}}{SET
mm{=i+3-12*INT(i/10)}}{SET yy{=100*e+g-4800+INT(i/10)}}{=dd*10^6+mm*10^4+yy
\# "00'-'00'-'0000"} \@ "dd/MM/yy"}

This will put taday's date in the header on page 1 and tomorrow's on page 2
etc. If you don't want the dates to update, change all the DATE fields for
CREATEDATE fields.
