Plain-date semantics · start date is not counted unless the result explicitly says inclusive.

How this calculation works

A visible path from input to answer.

Turn editable 30-, 60- and 90-day outcomes into inclusive calendar checkpoints and an exportable plan. The page keeps the calculation scope and its limits beside the result so the output can be checked, copied or revisited.

Calculation flow
  1. Read the record. The calculator uses Role, project or plan, Day 1, Review reminder time, Day 30 outcome and Day 60 outcome and 1 additional field supplied in the form.
  2. Apply the scope. It applies the User-entered role or project plan with inclusive Day 1 counting — organization expectations and performance decisions remain separate reference and the explicit date, unit and counting conventions shown in the result.
  3. Expose the checkpoints. Intermediate rows, warnings and timeline events stay visible; the emphasized row identifies the primary checkpoint when one exists.

Assumptions and scope

Calculation purpose: Turn editable 30-, 60- and 90-day outcomes into inclusive calendar checkpoints and an exportable plan. This is a high-sensitivity reference output; the linked authority or qualified professional controls the final decision.

Boundary behavior

Calendar inputs use plain year-month-day semantics. Leap days, month ends, date-pair order and unsupported dates are checked before the result is shown.

Questions answered

What to know before using the result.

Is the start date Day 1?

Yes. Day 1 is counted inclusively, so Day 30 is 29 elapsed days after the start and Day 90 is 89 elapsed days after it.

Can I edit the outcomes?

Yes. The Day 30, 60 and 90 outcome fields are copied into the result, image, calendar and CSV export.

Does this evaluate job performance?

No. It schedules your stated checkpoints and does not assess employment, project or performance outcomes.
