The full 21-day cycle
ShiftFlowr applies one chosen shift type to both seven-day work blocks. The dates move through the week because the full cycle lasts exactly three weeks.

The average is high when every shift lasts 12 hours. Check your
contract, breaks, and local working-time rules rather than assuming
every employer uses the same shift length.

7-3-7-4 FAQ
- Does this preset rotate days and nights?
- No. The built-in version uses your selected fixed shift type. Build a custom sequence if your employer changes shift type within the 21 days.
- Why does the anchor date matter?
- It determines whether any date falls in the first work block, the three-day break, the second work block, or the four-day break.
