When in military comms, we had some interesting rotations:
2-2-2-80 is one example.
8 on, 16 off, 8 on, 8 off, 8 on, 16 off, 8 on, 8 off, 8 on 80 off.
2-2-2-80 you would stand all three watches (day, mid, eve) twice every 8 days...with 80hrs off before you had to do it again.
Often you didn’t know what day, or time of day it was.
Another famous shipboard rotation was port and starboard. 8 on, 8 off, seemingly forever. Some skippers like to keep you on your toes lol
Yep - We called it 2 days 2 mids 2 eves. then two days off before we started days again. Base Security. Odd, thinking they gave an E-1 a .45 Cal to carry around with almost no police type training, but they did. They always thought the Seabees had more weapons prowess than we actually did at that rank.
I was 19 and running radar - catching all kinds of senior enlisted and officers for DUI’s. So weird now when I look back at it all.
