How to use this calculator
Enter a planning range, people and prior turn counts, chore intervals in calendar days and inclusive absence periods. All chores begin on the plan's first date.
The available person with the fewest prior plus new turns gets each chore. Ties rotate through the entered person order. Chores count equally and assignments follow date/chore order. The plan is limited to 1,500 turns.
A worked example
When Alex has one prior turn and Sam and Taylor have none, the first two due chores go to Sam and Taylor if both are available. An absence removes a person from that date's choices.
Does this balance how difficult each chore is?
It balances turn counts. If chores take very different amounts of effort, review and adjust the assignments before sharing the plan.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Daily attendance, office, coverage and chore plans allow up to 366 dates; school cycles, course plans and milestones allow up to 731. Dependency and historical workday calculations scan at most 3,661 dates. Class-session searches allow 366 dates and 200 sessions. Time-zone tools use browser IANA rules and require a choice when local times repeat. Dates and policy rules are entered manually; no employer, retailer, school or local weather policy is inferred. Copy, CSV and printing include the calculation rules; calendar exports appear when the result contains dated events.
