Drag & Drop Calendar

Problem Description

The problem is that when I need to rearrange my planning calendars, it gets very messy and can be extremely hard to do.

Proposed Solution

I need a planning calendar with drag and drop tiles that integrates with Google docs (or sheets if necessary, but docs is highly preferred). I want to be able to have a tile for each separate activity in a lesson that can be moved easily from one day to another if I need to rearrange. If you look at the calendar I included, you'll see how each day is separated. I would love for the calendar to be made of drag and drop tiles.
