The best way to calculate estimated birth time would be take the first day of your last period and go back 3 months and add 7 days.

time would be impossible. Date tho - do a search for pregnancy calculator online. I got this from a Yahoo search:

put in the first date of your last period and voila! You get a good idea of when you're due. But remember, hardly any women deliver on their due date!
