If you look through your cards, you'll notice that not one of them gives a date or time or period. That means you have to devise your own. And that depends on what suit you connect to each season. For example, I use: Diamonds = winter, Cups = autumn/fall, Spades = spring and Clubs = summer. Then the numbered cards will give you an approximate week within the season. So Ace of Clubs means early in summer. It's always good to have your timing system worked out before you ask a question about time.
And, to be perfectly honest, I find that (playing card) tarot is not too good for timing questions anyway. I prefer to take away the message of the card itself. Therefore my question would be, "What energy will surround my potential marriage partner?" Ace of Clubs says 'passion and inspiration'.
