sec-temporal-totemporalcalendar step 1.b:

b. If _temporalCalendarLike_ has an [[InitializedTemporalDate]], [[InitializedTemporalDateTime]], [[InitializedTemporalMonthDay]], [[InitializedTemporalYearMonth]], or [[InitializedTemporalZonedDateTime]] internal slot, then

i. Return _temporalCalendarLike_.[[Calendar]].
