esid: sec-temporal.calendar.prototype.monthdayfromfields
description: Temporal.Calendar.prototype.monthDayFromFields will return correctly with valid data.
info: |
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]]).
