How to create an event for facebook on iPod/ iPhone?

I need to make a need numbers event on Facebook but I can only use my iPod or iPhone coz my laptop is being fixed for 4 weeks! And I don't have a home computer
So I was wondering if you could still create one on iPod or iPhone

I don't think it is possible through the app - but i have found this that may help you by creating one through safari
