I've been playing around Adobe XD update: Component state. Must say XD did an awesome job in their updates in the past year.
Here is my UI experiment: Datepicker with small interactions based on the main scheme of the usage of the picker.
The Icon I used for design is my own Icon freebie: https://gumroad.com/l/line-icon-pack
Also you can download the XD file of Datepicker and use it for free. Maybe it will someone help.
Have a nice day,
