Traditionally, a card's number may be used to indicate a time factor. For example, the Ship, which is numbered "3", might be interpreted as time scales of 3 (e.g. "three weeks"). In addition to that, there are quite a few other time specifications for some of the cards. For example, I have seen the Man and Woman representing April and May. If you are interested in this kind of time determination, you will have to look it up elsewhere, as I don't treat of it here. This is because I personally don't use the cards' numbers for time determination, nor do I use most of the aforementioned additional time specifications. For I cannot see any relevant relation between them and the cards' meanings. I deduce a card's time factor exlusively from the card's general meaning.
