Calendar Alternative

[WythDryden]

Hey everyone,

I installed to the new leaked verizon rom, and after a lot of tinkering finally got it to work. But somehow it managed to screw up outlook on my computer, which I use for all my calendar appointments. I decided I'd uninstall and reinstall it, however, during the reinstall my computer crashed, and now I can't get it to reinstall no matter what. So I'm looking for a calendar substitute of outlook.

I did come across thunderbird with the lightning add-on, but to get it to sync I'd need to get BirdieSync, which costs about $27. As a college student I really can't afford that.

Does anyone know of any calendar substitutes that I could, preferably, use through activesync, that would be free? I've spent all day trying to resolve this issue, so any help would be GREATLY appreciated.
