I would like a simple countdown timer (preferably in days/hours/minutes) that counts down until 7pm on Tuesdays and during 7 - 8pm it displays a message with a link to another site, then after 8pm it starts counting down until next Tuesday at 7pm etc..

Is there a download for this or could one of you genius's design this for me.

Forever grateful!
Peh

Here is a link to a useful javascript countdown timer, but it would need to be modified to suit your needs:
