Perfume can last for many years without being opened, so you don't have to worry too much about the production date. Of course, if it's a common fragrance, it won't last too long, and some unpopular perfumes will have an earlier date, which is understandable, because few people are looking for it, and some people collect a lot of perfumes that are no longer produced, which means that this shelf life is very long, and nothing will happen if they don't open it.
