Quartz.Net - simple trigger scenarios

I'm currently in process of selec开发者_开发技巧ting a framework for building a scheduling system. It is quite simple (so i thought) it seems however that I can't get some scenarios to work with Quartz.

1. Every 4 weeks on Mon,Tue,Wed - been told that I can use cron to trigger every week and check somehow the counter - it doesnt seem very ideal.
2. Day 3 of every 5 months - would it be (* * * 3 0/5 * *) ?
3. The third Monday of every 3 months - I know I can use L for last not sure how to do first, second, third, fourth/last

I have so far been happy with all my other scenarios and it seems that Quartz.NET is a way to go, I just have to make sure that all my scenarios are possible.
