You've been changing date formats in articles from Month-Day-Year to Day-Month-Year.  While either is an acceptable format, you're not supposed to be changing date formats except for (i) maintaining internal consistency in the article or (ii) a reason to change it based on "strong national ties to the topic'. See WP:MOSNUM#Full_date_formatting  Your change [Diff Chopra Article], or example, is (i) inconsistent with the other date formats in the article and (ii) contrary to common usage in the US, where Chopra's entire professional career has been conducted.
