Make the check in history calendar from Sunday to Saturday like any standard calendar.

M- Saturday is just a ridiculously stupid way to look at a monthly calendar. No one does that

Additionally make it possible to actually be able to view an entire month at a glance.

The way it is set up now you can only pick a random date in the middle of a week and land on a random date in the middle of a different week. Your “search” often excludes the current day or a couple days. You can’t actually pick from the 1st to the 30th or 31st. I’ve tried.
