How it works.

  1. 01Open a recurring calendar.
  2. 02Review rule and exception diagnostics.
  3. 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.
