Gantt Chart Widget

I made this widget one year when my wife and I agreed to host Christmas dinner. Cooking so many different items all in different ways and hoping that they would all magically be ready at the same time - I decided that it was best not to chance it.

There are some free online Gantt chart tools but they all seem geared around working weeks and multi-month timescales. I wanted something much simpler to use e.g. for planning Christmas dinner.
