Been working on the "shadow Obama presidency' side-by-side.

This is very wide in excel.

Obama left - Trump Right with dates in the middle.

This is 2017 only.

You'll have to open the jpg to see it larger.

For the Obama dates, I used media articles and sources to capture the dates and locations.

Here are the hyperlinks from excel which are the open source date information noted in the spreadsheet.
