Tolkien in his novels used the traditional definition of New Moon (still in use in Islamic & Hebrew calendars), ie. the earliest visible waxing crescent. The calendar uses the astronomic definition of New Moon, which is about 18~36 hours before the traditional "New Moon". In his timeline he confused the two definitions, so his time from new moon to full moon is 1~2 days shorter than the primary world, and full moon to new moon 1~2 days longer.
