How it works.
- 01Open a recurring calendar.
- 02Review rule and exception diagnostics.
- 03Test a finite date window and inspect limits or unsupported cases.
The important details.
Expansion is bounded by time range, occurrence count and iteration budget. Unsupported period/exception cases are preserved and warned about.
A good question.
Can unbounded rules freeze the tool?
Safety budgets stop expansion and report truncation. No tool expands an infinite series.
Keep going.
