Apologies to the list for practically spamming this recently, but it
seems directly relevant:

https://github.com/abo-abo/tiny

It has built-in support for Org dates with its %(date) function.
Apparently it can be used like this:

m\n8|**** TODO Learning from Data Week %(+ x 2) \nSCHEDULED: <%(date "Oct 7" (* 
x 7))> DEADLINE: <%(date "Oct 14" (* x 7))>

Which results in:

**** TODO Learning from Data Week 2
SCHEDULED: <2013-10-07 Mon> DEADLINE: <2013-10-14 Mon>
**** TODO Learning from Data Week 3
SCHEDULED: <2013-10-14 Mon> DEADLINE: <2013-10-21 Mon>
