Hi Jilly,
I agree with all the others!
If you're really hooked and want some reading material, Toni Weschler's book Taking Charge of Your Fertility will answer almost all of your questions and help you to understand more about optimal intercourse timing.
The thing about 'ovulation day' is that you can never be sure of exactly when it is... you can guesstimate to within a day or so. If you use OPKs, they predict that ovulation will occur within 12-36 hours of a positive result (though many women don't get + results at all on them!) and if you're charting your temperature, you may find your temp rises on the day of ov, the day after, or slowly over the next few days... So you basically make an educated guess based on all your fertile signs.
There are a couple of websites based on the Fertility Awareness Method -
www.fertilityfriend.com and
www.ovusoft.com. Most women on here who are charting seem to use FF - it's very user-friendly, plus it's free for basic features for a limited time, so you can trial it first. I believe Ovusoft charges immediately.
The egg survives for 12 hours after ovulation, sperm typically survive 2-3 days in fertile conditions, and take approx 2 hours to get to where they need to be for conception (top of Fallopian tube). So if you happened to ovulate at 6am on O day, and had intercourse that evening, you'd be too late. If you happened to ovulate later on that same day, say at 11pm, you'd still have a chance of conception if you had intercourse the following morning, O+1. Most books advise intercourse every other day from 8 days or so before expected ovulation (in case you O early), then every day from 2 days before ovulation until 1 day after, inclusive.
Hope that helps.

Shame to you all that looked and didnt reply!!!
I guess this is because of the number of lurkers - you need to be registered and logged in to post. I sometimes look at the site from the library, when I'm researching there, but I'd never log in on a public computer - not least because the pcs there are all set up so you can't log in to anything other than your library account, even email. Look but don't touch! I only log in to sites from my home computer... Lucky I work from home most of the time!
