I use trash pickup day, Thursday, as a reference day. How do you keep track of the days? Humour if possible.
I get up in the morning (usually), pour a mimosa and settle in front of my Mac to read my news, weather (it’s Florida, go figure), peruse A-mug and the fishing report. So the day and date is the first thing staring me in the face.
Absent that, it would be a mystery.
