Someone code this countdown for me

Alright, I know this is more of a javascript/php thing rather than programming, but I figured this fit here better than the other boards. If anyone is bored, this is what I'm looking for:

- 3 buttons
- each button starts (or resets) a separate 13-day countdown when pressed (it would be nice if there was something visual for the countdown too, plain text is fine)
- If any countdown reaches zero, an email is sent to my inbox informing me which one it was

I don't go to school. There's an online game I play, and if I don't login for 2 weeks my account is auto-deleted (thus 13 days to give me a 1 day heads up).

Also, what class assignment would say "php or javascript is cool, whatever, just fuckin do it"
