How it works.

  1. 01Paste the repeat rule and enter the first event date.
  2. 02Choose the date window you want to preview; an optional event time is interpreted in UTC.
  3. 03Read the explanation, browse the scheduled dates and review any warnings.

The important details.

A first event date is required because a repeat pattern needs a starting point. This is a local explanation and bounded preview, not a calendar-file creator or an account connection. Unsupported patterns and incomplete previews are reported rather than guessed.

A good question.

Why are some months skipped?

Repeat rules skip dates that don’t exist instead of moving them—for example, a monthly event on day 31 skips months without a 31st.

Keep going.
