About OccultCalendar

OccultCalendar is an independent astronomical almanac with optional cultural, historical, and spiritual interpretation layers. It is designed for curious newcomers, experienced practitioners, and people who want the astronomy without adopting any belief system.

One sky, clearly separated layers

The calculation layer covers observable or computable events such as planetary positions, Moon phases, retrograde motion, eclipses, seasonal crossings, and local sunrise and sunset. The site then distinguishes sourced observances from traditional correspondences and personal reflection prompts.

An astronomical event can be calculated. Its spiritual meaning cannot be established by astronomy. OccultCalendar therefore labels interpretations as interpretations and does not promise outcomes.

Editorial principles

Reproducible astronomy
Calculations identify their data source, time convention, location assumptions, and zodiac convention where relevant.
Neutral inclusion
Documenting a movement is neither endorsement nor condemnation. People choose which material they see.
Specific sources
A claim should identify the community, movement, text, or historical context it comes from instead of implying universal agreement.
Cultural care
Living, community-rooted, and initiatory traditions require specialist review and a distinction between public and restricted material.
User choice
A selected tradition is a content preference, not an identity declaration. An astronomy-only experience is always available.
No harmful promises
The site does not guarantee spiritual results or replace medical, legal, financial, or mental-health professionals.

Current status

The live astronomy engine uses Skyfield with the NASA JPL DE440 ephemeris. Some inherited tradition pages are undergoing source and cultural review; those pages are visibly labelled and excluded from search indexing until reviewed.
