A stated classroom effective-date delay can be recomputed exactly. Honesty note: simplified federal agency and regulatory model; jurisdictions and programs vary; the pinned first step states the as-of date; not legal advice.

Effective-date delay is a stated classroom rule
This lesson uses a toy stated delay, not a universal APA rule. The model starts from publication date and an exact day count.
publication date+stated delay
Example publication data
Publication is modeled on June 1, 2026 plus 30 calendar days.
days=30
The date arithmetic recomputes the effective date
In this stated classroom rule, publication on June 1, 2026 plus 30 calendar days gives effective date July 1, 2026.
effective date=July1,2026
Diagram note
The diagram is date arithmetic for a toy effective-date window. It is not advice about any real rule's operative date.

Summary
Effective-date modeling should show the trigger date, count rule, computed date, and caveat that real programs vary.
