Tracking Marriage Anniversary Date in RE

We do the same, the date from on the relationship record.  If you only have the month and day, you can still enter it there with 9999 as the year.

I also just found a record in my database where the anniversary date was recorded 2 places - where I detailed in my first answer to you, but also as a phone type of "Notes" (formatted as a text field) on the Other tab in the phone & email area of the Bio 1 tab.  I like it there too, so I'm going to see if I can make that our standard practice.  Yes, it's a bit of redundancy, but I have people who look different places in the records for their information, so something like this would be nice to have available in more than one spot.
