Thanks everyone !!!
This was a tough one and there are a lot of great submissions by both experienced and newcomers to Power BI – that to me is truly amazing and a joy to see. Same goes for the increasing numbers of non-member participants 
There’s so much to learn from these challenges, it’s mind blowing.
We all poses unique analytical insights and techniques making the challenges the perfect platform to explore and develop new skills and share that knowledge with each other.

@haroonali1000, in regard to “suggesting appointment dates”
Looking back I’d definitely go for generating a list in Power Query. Just one custom function allows you to extract so many different insights and planning perspectives - really powerful stuff IMO…
