Yes, their website says March 30th to March 31st
It says March 30-31 on mine.
That info (as far as I know) is in the pass holder section which you have to log in for. Unless I missed it, I didn't see that info on their general site.
Passholder ot not the website will let anyone view the schedule of which ever park you choose to go visit.
I don't know on top of my head but you should be able find this information on their website
