Timing in Tarot comes through by suits or Major Arcana for me.
Cups are days, Wands are weeks, Pentacles are months, and Swords can be days, weeks, or months. So if in the timing position of a spread or if asked directly the 3 of Cups, for instance, would be three days. the 6 of Wands would be six weeks, the 2 of Pentacles would be two months, and the 4 of Swords would indicate four days, weeks, or months.
If a Major Arcana card presents itself for time, it shows specific dates relating to astrological dates of the zodiac. So if I were projecting a time frame and the Chariot dropped out of the deck, I would see that the timing would fall between June 22 and July 23.
