internal/household provides Today, WeekStart, WeekDays, WeekLabel, PeriodKey and LocalTime, all in the household IANA zone and never the process zone. Weeks are ISO Monday to Sunday; calendar arithmetic runs on UTC midnights so DST never shifts dates. LocalTime reads a skipped or repeated wall time with the UTC offset in effect before the transition: a spring-forward gap moves forward by its length, and a fall-back repeat is its first occurrence. store gains LocalDateOf and LocalDate.Date so household builds dates without reparsing, and LocalDate.Value rejects years outside 0000-9999.
