Event Scheduler App

I am looking to make an event scheduler app just like the following website http://comiccon2013.sched.org

I was wondering up anyone can recommend any gem or things to look out for while I am tackling this new side project.

Nothing jumps out at me immediately, but one resource I’ve used for questions like these is https://www.ruby-toolbox.com/

Worth browsing through from time to time.

Thanks for the response, I looked at the toolbox and probably will just have to play with the gems to see what works
