  1. Let calendar be the this value.
  2. Perform ? RequireInternalSlot(calendar, [[InitializedTemporalCalendar]]).
  3. Assert: calendar.[[Identifier]] is "iso8601".
  4. If Type(fields) is not Object, throw a TypeError exception.
  5. Set options to ? GetOptionsObject(options).
  6. Set fields to ? PrepareTemporalFields(fields, « "day", "month", "monthCode", "year" », « "day" »).
  7. Let overflow be ? ToTemporalOverflow(options).
  8. Perform ? ISOResolveMonth(fields).
  9. Let result be ? ISOMonthDayFromFields(fields, overflow).
  10. Return ? CreateTemporalMonthDay(result.[[Month]], result.[[Day]], "iso8601", result.[[ReferenceISOYear]]).
