First I look at the numbers in the cards Wands is summer and days or hours Swords is spring and weeks Cups is autumn and months Pentacles is winter or years The star, the moon, the hierophant, the lovers, the chariot, strength, the hermit, justice, tower, temperance, the devil are all associated with a zodiac sign so you can also use that for ex strength can be associated with Leo season which occurs between the 21st of July to the 21st of August

Personally I don't use dates in tarot readings a lot because tarot is more about current energies to me and I only ask about the past and what fits more my friend likes dates a lot more and she really impressed me when she gave me the 2nd of April and the 14th of March as significant dates for bnb considering she isn't a fan at all, I'm probably gonna share more of her readings later
