Direct answer

Monthly recurrence follows the calendar; cycle-day recurrence follows a recorded cycle

A monthly reminder returns on a fixed calendar rule. A cycle-day reminder returns on the selected relative day after the next cycle start is recorded. Choose based on what the routine actually means, not because the dates happened to match once.

Actual Umorrow workflow

  1. Create a new event and choose Cycle day.
  2. Select the relative cycle day and a reminder time.
  3. Keep repeat enabled when the routine should return in later recorded cycles.
  4. Save and review the next occurrence in the calendar.
  5. Update the recorded cycle when a new cycle starts so later occurrences use current context.

Why “every month” is different

Calendar months have different lengths and do not move with personal cycle timing. A reminder on the 15th remains the 15th. A reminder for cycle day 15 is recalculated from the recorded cycle start.

Good neutral examples

Use cycle-day recurrence for personal planning routines whose meaning is explicitly relative to the cycle. Use fixed recurrence for rent, birthdays, work deadlines, reservations, and other commitments defined by the civil calendar.

When to keep a fixed date instead

If missing the exact date has consequences, keep the event attached to its confirmed date. Cycle context can still appear beside it in the calendar, but the commitment itself should not move with an estimate.
