I am well aware of the fact that there is little interest in spreadsheets these days.
Nowadays things are about mobile devices, variable user interface, social media and apps.
But I just felt like sharing this one due to some of the "interesting" observations about days of the week one can play around with in Excel or Google Spreadsheet.
Tab to sheet "b" as well and test some of the observations. Drink tea or coffee while you are at it, or better yet have a beer or a martini or whatever is your tipple.
