 :::Hi, Adam, please try to remain calm. I haven't undone your work, all I've done is ""tweaked"" it. The date format in an article should be consistent. Some topics will use ddmmyyyy and some will use yyyymmdd based on national variation. Either is fine, so long as there is consistency in an article. This is accepted as good practice within Wikipedia as a whole and is a ""requirement"" at higher levels (e.g. GA, ACR, FA). Your edit was fine, you just need to remember to maintain the consistency of style that is already in the article. By adding ""df=yes"" to the infobox template, the dates can be auto presented, but in the ddmmyyyy format. The relevent policy documents to read are WP:STRONGNAT and WP:DATERET both of which are sections of WP:MOSDATE. Additionally, it  was not correct per WP:DASH to use emdashes in year ranges, so that is why I changed them. Please don't think that I changed your work because I don't value your contributions. As I've stated before, I greatly appreciate your work, and that is why I gave you a barnstar: to encourage you to continue. However, in this case I feel you were slightly incorrect. That happens; we all make mistakes, including me, and other editors will change things that they disagree with. That is the nature of working on Wikipedia. Of course, I hope that you will continue editing and I'm happy to continue to answer your questions if that is what you want. If not, then I wish you well and take care of yourself. Regards,   "
