Anyone know how I can sync my macbook pro ical with the one on my ipod touch?

I had all my calanders on my laptop which sync'ed with my ipod touch but now icloud has deleted my calander on the laptop and since i still have all the data on my ipod touch I just want to put it back onto the laptop.

Ive found lots of sites saying to to sync from laptop to iphone/ipod but i need to do it the other way.
