My best schedule ever was also military, but it was 7-3-7-4: 7 8-hour "afternoon shift" days, then 3 days off, then 7 8-hour "day shift" days followed by 4 days

My best schedule ever was also military, but it was 7-3-7-4: 7 8-hour "afternoon shift" days, then 3 days off, then 7 8-hour "day shift" days followed by 4 days off. The 3-day time off was Tuesday-Wednesday-Thursday, and the 4-day was Friday through Monday - and because you were getting off the early shift and going onto the late shift, it seemed like a longer break. Of course, that implies shift work and three crews for 16-hour/7 day coverage. (The "graveyard shift" was a skeleton crew, and your turn would pop up every four months or so. Air force. It was basically for emergency landings for civil and allied aircraft and such, with some swabbing of the decks for busy work.) The work week was long, but there was plenty of time to get stuff done and to wind down. Hell, you could even cram in a weekend getaway without a lot of stress.
