You don’t actually have to play every day for a month for this achievement like I thought at first. All you have to do is play and complete every daily challenge for a particular month. If you missed a day, that’s okay. I played the entire months worth of daily challenges and got the achievement as soon as I completed the last one. You can play in any order also as I played the easy ones first, then worked my way up to expert. Also note that doing this method will NOT award you the achievement for playing 5 daily challenges in a row, but will give you a diamond badge when you finish as well. Hope this helps!
