xl2003, winXP

I have a range of 10 URLs. A10-A19 Each day I need to update them to the
current date. The URL looks like:-

URL;http://www.tabonline.com.au/2006/02/23/NR05.html


So tomorrow I will want to be able to push a button and /2006/02/23 becomes
/2006/02/24 in all 10.
I need to do this programatically as it will be part of a series of
operations.
Any help would be greatly appreciated.
Ta,
Martin
