add a monthly calendar overview or 3 weeks

I'm missing the possibility to show a calendar on the watch like timely for Pebble.

At least 3 weeks if not a month would be great.
It should be possible to set the start day (Sunday, Monday, Saturday) and if you want the current week to be on top most with 2 weeks below or in the middle with 1 week before and one after or down most with 2 before.
The current day should be highlighted.
