Convert between the plain types

Temporal's toPlainDate(), toPlainTime(), toPlainDateTime(), toPlainYearMonth() and toPlainMonthDay(). A plain_year_month() needs the day and a plain_month_day() the year to become a date; both resolve it with overflow = "constrain", as Temporal does.

temporal_to_plain_date(x, ...)
