Question is there a way to find out the date or dates you ranked up?
If you screen-shotted the promos, then just look at the date it was created.
Otherwise, I don't think there is.

Though this site only keeps 3 months data, so not very useful for you.
Other option is:
http://battletracker.com/bf2playerhistory/43386237/
And find when you got the points needed for each rank from (Score History(monthly)). But its not very accurate.
