OK I found a very simple way to do this without the need to sync with anything or have an account with anybody like google or whatever.
Here is it below for anyone else who would benefit from this.
*Adding Subscription Calendars*
Just point Mobile Safari on your iPhone to:
http://www.apple.com/downloads/macosx/calendars/. Apple provides categories for Most Recent, Most Popular, Alphabetical, Staff Picks, plus a handy search box. Once you find a calendar that interests you, click the Download link.
Your iPhone will ask if you want to subscribe,and once you confirm, will offer to take you straight to your calendar events to see what’s new.
