Panama vs DuPont Schedule: How the Rotations Differ
These two schedule concepts can look similar until you compare the number of workdays, hours per day and calendar pattern. The tables and examples below focus on time math rather than employment classifications. The focus here is panama vs dupont schedule, with a method that stays within practical time and schedule arithmetic.
Quick answer
For example, a 4/10 pattern uses four 10-hour workdays, giving 40 scheduled hours across those four workdays before any organization-specific adjustments.

Compare the inputs, not just the label
For a useful comparison, write down workdays per cycle, hours per workday, total scheduled hours, and the number and spacing of days off. Two schedules can have a similar weekly total while feeling very different on a calendar.
A simple comparison checklist
- How many calendar days are in the repeating cycle?
- How many of those days are worked?
- How long is each workday?
- Does the pattern rotate or stay on the same weekdays?
Worked example
For example, a 4/10 pattern uses four 10-hour workdays, giving 40 scheduled hours across those four workdays before any organization-specific adjustments. After you have a correct hours-and-minutes result, convert it to decimal hours only if the destination system actually uses decimals.
Common mistakes
- Assuming every employer uses the same rotation start day
- Confusing scheduled hours with paid hours
- Treating a pattern preview as an official calendar
What this calculation does not tell you
The arithmetic does not determine wages, overtime eligibility, attendance status, break entitlement, taxes or employment classification. Those questions depend on workplace rules and, in some cases, law. This guide intentionally stays with the time calculation itself.
Use the calculator
If you do not want to calculate the values manually, open the Panama Schedule Calculator. The calculator shows the result and a breakdown so you can compare it with the method above.
Build the cycle before judging the schedule
Write the repeating sequence across at least two weeks—or a full rotation for longer patterns. That makes clusters of workdays and days off visible. Looking only at an average weekly number can hide how unevenly the hours are distributed across the calendar.
Use a real start date for planning
Once the pattern is clear, anchor it to an actual calendar date. A different start date can move every workday and day off even though the underlying rotation is identical. That is why the calculator asks for a schedule start date.
Do not compare averages alone
An average can hide how work is distributed. A schedule with fewer long days can have the same total hours as one with more short days. Compare the actual pattern, not only the weekly average, if the calendar experience is part of the decision you are trying to understand.
Frequently asked questions
Should I round before the final step?
Usually it is clearer to keep the exact minutes through the main calculation and round only the final displayed value if rounding is needed.
What if a shift crosses midnight?
Treat the end time as occurring on the following day. That converts the problem into a normal positive duration instead of subtracting a larger start clock value from a smaller end clock value.
Why can a timekeeping system show a different total?
Systems can use their own rounding, break, calendar and schedule settings. Compare the original entries and assumptions before assuming either result is wrong.
