Android calendar on shows a subset of what's on Google calendar

Question

I have seen so many different posts regarding calendar problems that I'm sorry if this answer is already out there, but I can't find it by searching so I'm going to ask for myself:
I have a Google Calendar that works fine when I create/update entries from the web. I do not use Google Calendar Sync or any other SW to communicate with my Android phone (Droid 2) and I do not have/use Outlook.  My phone calendar is set up and it shows everything correctly for the current and past 6 weeks.  Updates made on either calendar (web and phone) appear on the other in less than a minute, so the basic Sync function seems to have the capability to make the correct updates.
I created my Internet Google Calendar around Sep 2010 (when I got this phone) and I created past events for record keeping purposes (I added details of a vacation in 2009, a business trip in Spring 2010, etc),  I also created several recurring events that extend for a year or more into the future (like music lessons and task deadlines).  All of these are clearly visible on my Google calendar when I access it from the web and when I access it on my phone via the Internet.
However, when I use the onboard calendar function it does not show any events older than 7 weeks except those that were created as recurring events.  It also show only 1 recurring event starting past this week--it loses recurring events that start in the past and extend past next week along with losing recurring events that start and stop completely in the future.
The net result of all of this is to render that onboard calendar function pretty useless--to get an accurate view on my calendar I have use a shortcut to access my Google Calendar through the Internet.  I am perplexed why there should be so many users with documented problems related to syncing their web Google Calendar with their phone calendars on a platform developed by Google. Similar calendar complaints seems to fill the Google forums from 2009 through today with not much in the way of solutions or work arounds offered. My old Palm Tungsten PDA may not be able to sync wirelessly, but when it did sync it had all my events,
Can anyone think of anything I could be doing wrong that causes these problems?  Does anyone have any advice on how to overcome these problems?
(I've already spoken with Verizon and Motorola support:  1) I already tried completely deleting all calendar data from my phone and reacquiring via a new setup; 2) I've reset my phone to factory setting and reloading everything; 3) I had them send me a replacement phone in case it was a programming error on my phone but the replacement acted exactly the same way.)

Answer 1

I have been researching this problem since it first surfaced with the 2.2 Froyo updated on the Droid X for me.   It is unbelievably frustrating.  I basically run my life with my calendar, and also use it as a journal to document what I do.   There are two fundamental problems:  
1 - the sync only will bring in appointments to about five or six weeks prior to the current date, not any in the further past;
2 - the sync hangs up and fails to complete the synchronization.
I have read hundreds of posts related to these issues on this Verizon forum, and also on Droid Forums.   Scores of customers seem to experience these issues.
When I first got the Droid X, I noted the failure to sync past appointments, and finally after many hours on the phone with Verizon support and reading many posts, I learned the trick of manually setting the phone date to some time in the past, since it will sync future events to the gmail calendar.  That had issues as well, as it used to only sync 1 year into the future, so I had to keep resetting the phone date to past dates one year at a time to rebuild my calendar from 2005.  This no longer works because of problem #2 - synchronize stops and fails.   Verizon phone support admitted that they have had complaints about this problem as well.
I have checked all Accounts settings, auto sync, power widget (trick from the developers forum), factory reset and rebuild of environment, removal of possibly interfering market applications such as task killers and virus protectors, system recovery utility->clear cache partition, etc.   I have tried everything that I have found a suggestion for or thought might solve the issue, all to no avail.
At one point I thought it was a Google issue, but when I setup a new Macintosh computer, iCal synchronized every single appointment and event back 7 years and forward from the current date flawlessly to my Google gmail calendar.   The synch on the Droid X will run for perhaps 10 seconds and then the little icon with the arrows stops spinning and it just hangs there, having brought in only 15% or so of my thousands of appointments from my Google gmail calendar.
Maybe it is a size problem, since I have so many appointments.  Or maybe not.  No one seems to know.  No response from Google support.   I have posted extensively about this issue on Droid Forums (username Tedmeister there) if anyone is interested in looking at those posts (and the many folks experiencing similar issues).   Verizon support is clueless, and only suggests another factory reset "try and see if it works".  Sigh.
The problem has gotten MUCH worse since the 2.3 Gingerbread update, as well as some additional handset problems being introduced by that update.  Some of these Verizon has also admitted knowing about, and just say 'Google is working on the fix'.
I am pretty much at the end of the rope on the calendar sync issue.   The only thing I have not yet tried is to hurl the Droid X through the window and go buy an iPhone  :-)  
So anyone out there who has looked into this deeply, or has any inside information about the causes and/or solution, I'd love to hear form you.
