Hour Mechanics

How They're Calculated

⚙️
  • Sunrise → Sunset: Split into 12 equal day hours for outward magic.
  • Sunset → Sunrise: Split into 12 equal night hours for reflective or banishing work.
  • Elastic timing: Expect 35–80 minute hours depending on season + latitude.
The closer you are to the poles, the more dramatic the shift between day and night hours—plan accordingly.

Field Notes

Hour Insights

Elastic Hours

Hours stretch with daylight. Summer day hours are longer.

First Light

First hour after sunrise always matches the day's planet.

Stack Timing

Layer day + hour + moon phase for precise timing.

Day vs Night

Two Different Temperatures

  • Day hours: Amplify manifestation, business, healing, or visibility spells.
  • Night hours: Favor shadow work, divination, dream magic, and bindings.
  • Transition periods: Sunrise + sunset hours are liminal—perfect for threshold workings.
Combine with lunar phase for nuance: waxing + day hours accelerate growth; waning + night hours sharpen release.
