Divination & The Harry Potter Series

Season 13 of Every Day Tarot is all about divination, and today’s episode is about the magic of numerology—or, as it’s called at Hogwarts, Arithmancy. 

Numbers aren’t just numbers in the wizarding world; they're magic. But numerology goes far beyond lucky or unlucky numbers! From Voldemort’s obsession with the number seven to Hermione’s absolute love for Arithmancy, it’s an ancient system that sees numbers as carriers of energy, meaning, and destiny.

What we explore in this episode:

• The history of numerology and its roots in divination

• Why numbers are seen as energetic, symbolic, and deeply influential

• How arithmancy appears in the Harry Potter books (and why Hermione loves it)

• The cultural obsession with numbers and their magical resonance

Numerology: The Magic in NumbersNumerology is the study of numbers as symbols carrying energy, direction, and influence. Each digit from 1 through 9 carries its own vibration: beginnings, intuition, creativity, stability, curiosity, harmony, spirituality, ambition, completion. Larger numbers are reduced back to these roots, and repeating digits (11:11, 333, 444) amplify their meaning.

Numbers show up everywhere: birthdays, addresses, names, and even in pop culture. In the tarot, numbers shape archetypes through the Major Arcana, beginning with 0 (the Fool) and cycling through the archetypal journey until 21.

Arithmancy at HogwartsIn the wizarding world, numerology takes the name arithmancy, and it’s Hermione’s favorite subject. While she dismisses Divination as “woolly” and subjective, she praises the logical, chart-based approach of arithmancy. 

Even Voldemort is obsessed with numbers: he creates seven horcruxes, deliberately choosing the most magically potent number in the wizarding world. J.K. Rowling herself plays with sevens and twelves constantly in the series. And in Muggle culture, we see echoes of the same beliefs—seven as “lucky,” 13 as “unlucky,” 11:11 as a moment to make a wish.

To explore the energy of this episode, I pulled cards from The Citadel: A Fantasy Oracle by Fen Inkwright

• The Patron - mentorship, finances

• The Catalyst - radical change, taking control

• The Gambler- loss, risks

💭 Today's Tarot Pull:

From The Herbcrafter’s Tarot, I pulled the Nine of Air Pomegranate (Upright).

This card speaks to grief, release, and the cyclical nature of endings. Like Persephone eating the pomegranate seeds, it reminds us that even in loss there is wisdom, and that endings prepare us for beginnings.

Reflective prompts on this card:

• What cycles in your life are completing right now?

• Which number patterns or “angel numbers” keep showing up for you?

• Where can you honor endings as sacred, rather than resisting them?
