Timing

The question tarot is worst at, asked properly.

What the method is. In the traditional table each suit carries a unit and the card's number carries the count: Wands are days, Swords are weeks, Cups are months, Pentacles are years. A Three of Wands is about three days. That is the whole mechanism, and it is a convention rather than a measurement. Other readers swap Swords and Cups, and some refuse the exercise altogether.

Majors and courts have no timing. A Major Arcana card describes a condition rather than a schedule, and a court card describes a person. When they turn up here the reading is telling you the delay is structural or that it is somebody else's decision, which is more useful than a fabricated date.

Read the agreement, not the average. Three cards in the same suit is the strongest signal this method produces. Three cards in three suits means the parts of the situation are moving at different speeds, and averaging them into one number would throw away the actual finding.

What to do with it: treat the answer as a shape. "Weeks rather than years" is a genuinely useful thing to learn about a situation. "The fourteenth of next month" is not something a deck of cards can know.
