| 2. Perform ? RequireInternalSlot(calendar, [[InitializedTemporalCalendar]]). |
| 3. Assert: calendar.[[Identifier]] is "iso8601". |
| 4. If Type(temporalDateLike) is not Object or temporalDateLike does not have an [[InitializedTemporalDate]] or [[InitializedTemporalYearMonth]] internal slot, then |

| 5. Return ! ISOYear(temporalDateLike). |
