  3. Run the Weekend and Night-Shift Fairness Calculator with a baseline set of values, then change only one uncertain input at a time when comparing alternatives.

Calculation

Method used

Weekend and night counts are totaled per person and the highest-to-lowest spread is compared with tolerance.

Assignment spread = highest combined weekend/night count − lowest combined count.

The displayed formula makes the role of Assignments by employee and Allowed assignment spread explicit. In the Weekend and Night-Shift Fairness Calculator, keeping those inputs separate helps distinguish a changed assumption from a changed calculation rule.

Calculation method last reviewed: June 20, 2026.

Worked scenario

In the Weekend and Night-Shift Fairness Calculator, if the direction or scale looks wrong, verify Allowed assignment spread before changing several inputs at once.

Interpretation

Interpreting the headline metric

A small count spread can still hide unequal holidays, shift lengths, preferences, or consecutive burdens.

Read the headline together with the supporting metrics for Assignments by employee and Allowed assignment spread. A plausible-looking Weekend and Night-Shift Fairness Calculator result can still be unreliable when one of those values uses the wrong unit, date boundary, or local convention.
