Tattvic Tides Calculator
This calculator presents the five tattvas as a timing instrument with selectable methods. Use sunrise-based, fixed-clock, or custom-start cycles depending on the convention you are studying.
Sources differ on timing conventions, so the active method is always shown with the result. Symbols and colours follow the Golden Dawn tattva cards: a yellow square for Prithivi, a silver crescent for Apas, a red triangle for Tejas, a blue circle for Vayu and an indigo egg for Akasha. Associations are traditional correspondences, not scientific claims of causation.

How tattvic tides are modeled
The five tattvas are presented as a repeating elemental sequence. Because source traditions differ, this calculator lets the user choose a sunrise-based cycle, a fixed clock cycle, or a custom starting point, and can show primary tattvas alone or primary-within-subtattva subdivisions.
