Can the court cards just tell you the seasons since they don't have numbers. Example, each suit represents a season. A season is 3 months long. Four courts would be 3 months divided by 4. So 90 days divided by 4 equals 22.4 for each Court Card.
So let's say that the Outcome is Page Pentacles for timing, then that means the first 22.4 days of Fall (if the consensus is that Pentacles = Fall, or whatever system you use). Since Fall starts on Sept. 21 Page Pentacles from Sept. 21st to October 11th.
The Major Arcana would be whatever zodiac sign and date the card represents. For instance, the Moon = Pisces (Feb. 21st to March 21st.). However, I don't know what you would do for High Priestess. Yes, that card is influenced by the Moon, but I don't think you can use the Pisces zodiac with this. I think that MAYBE the card is telling you the situation of the event, more than the date.
For example. "When will I meet a new lover?" Moon. Between February 21st to March 21.
Or
"When will I meet a new lover?" High Priestess, a major event that is mysterious or surrounded by the occult. Or you doing research on someone, or someone doing research on how to contact/find you.
This leaves an open ended date.
How do you feel about what I said. I kind of made it up as I went along based on my intuition.
