Thank you all for some great information to look at for ways to best solve my problem.

I need some hints on how to best get myself out of a problem I have created with my data.  Many years ago I started data entry in another genealogy program and used the date format mm/dd/yyyy as that was the most familiar date format used in USA and when I changed to TMG I imported that data.  I also used that same date format in TMG for many years.  About a year or so ago, I switched to the more universal date format dd/mm/yyyy.  Immediately after the switch I checked around and it seemed to correctly make the change, so I began entering any event based upon the new date format.  Now to the problem, I was entering an additional source on some old data and noticed the date was wrong.  Instead of  9 Feb 1701/2 it said 2 Sept 1701/2.  These were the dates when the calendar changed where Jan-March changed to a different year (Julian to Gregorian calendar).  I don't know yet whether other non standard dates like when circa, before, after, etc. have  been used are also messed up or not yet.  I need an understanding of how TMG treats dates that were imported and non standard dates when the date format changes to figure out the best way out of this problem I created.  I have over 5000 people in my database.  Is the best thing to do to return to the mm/dd/yyyy format and then recheck everything done since a specific date?  Is there anyway to make a list of what has changed in the database since a specific date?  I do have TMG Utility and am running TMG 9.05.  I also have backups from various times to go back to try to figure out when I made the date change although that would be very time consuming.  Suggestions?
