"So can I assume the solar timing is similar, just based on position in the sky although the date will be accurate since we are using a solar calendar?"
The solar cycle is a different sort of thing. In their simplest form, they follow metaphors of the seasons in an agrarian community. For example, spring is a time for eruptive new life, outpouring of vital force, and seeding. Summer is a time of maximum solar force, outward-turned activities, and the development and maturation of the seeds planted in spring. Autumn corresponds to full ripening of what was previously set in motion, and the harvest; but some seeds are planted in the fall that germinate through the winter. Winter corresponds to a time of outward latency, maximum in-turned activity, and the hidden (often unsuspected) gestation of things that erupt into quick growth of springβs next coming. In the metaphor of the human life-cycle, spring corresponds to human birth, summer to the course of mature life, autumn to ripeness and death, and winter to the latency between incarnations.
In the book, I give a much more granular differentiation of the parts of each season - one rising and falling wave that moves around the whole year - but the above covers the basics.
