info: |
  1. Let calendar be the this value.
  2. Perform ? RequireInternalSlot(calendar, [[InitializedTemporalCalendar]]).
  3. Assert: calendar.[[Identifier]] is "iso8601".
  4. Set one to ? ToTemporalDate(one).
  5. Set two to ? ToTemporalDate(two).
  6. Set options to ? GetOptionsObject(options).
  7. Let largestUnit be ? ToLargestTemporalUnit(options, « "hour", "minute", "second", "millisecond", "microsecond", "nanosecond" », "auto", "day").
  8. Let result be ! DifferenceISODate(one.[[ISOYear]], one.[[ISOMonth]], one.[[ISODay]], two.[[ISOYear]], two.[[ISOMonth]], two.[[ISODay]], largestUnit).
  9. Return ? CreateTemporalDuration(result.[[Years]], result.[[Months]], result.[[Weeks]], result.[[Days]], 0, 0, 0, 0, 0, 0).
