Simple Online Dates Calculator?

[NotQuiteCockney]

I need an online tool that will let me know, given that someone is X weeks pregnant on Y date, what their due date is. I don't need it to be terribly accurate, just within a week or so.

I know, this is very lazy of me, but counting wears me out, and I need to do this sort of calculation a few times per week these days.

something like this?

You need one of those SMA-sponsored wheel-type things

Sorry - small formula company rant. They get everywhere, don't you find?

Which, the rants? Or the formula companies?

I'd rather not have an object as I will just misplace it.

Yeah, Tamba, the second one is the link I'd found earlier and used ok. Those calculators all assume you know the date of the last period, which I never do know, I just have a statement of "I am currently X weeks pregnant", when I need to know their EDD.

Hi,
There is a good one on the NHS Direct website where you can just click on the number of weeks pregnant you are or try the one on the BBC website as I'm sure it gives you a due date too.

Have a look at this

I hope the links work - wasn't too sure what I was doing!
