I have been alive the second half of the 20th century and first quarter of the 21st.
I have witnessed constant chaos because people of character refuse to accept the actual time they get living equally alive daily here. My brain navigates a day dawn to dawn but rule of law defines a day by midnight to midnight by the longitude 0 passing by 360 degree mid night each rotation and that longitude 0/360 only exists because humans created the idea of calendars and clocks to measure human behavior cradle to grave each generation gap inhabiting space daily here.
Factual space time divides one rotation into 2 of 7 days a week in sequence 52 times a year.
