using datestamp?

Hi,

I am trying to do a little library script, where a user can search for a book, and then book it out for 1 month.

All is well, exept I don't know how to make the script to start the booking at todays date and to last for one month and then clear from the bookings table.

I use an Access database.

What column should I have in my database?
should it use datestamp for when the booking is make and then have another column with datestamp + 31 days or something?

How can I do that?
what should I add to my insert records sql?
I don't have a clue here.

Can you help?

Thanks,

Vinny
