Mundane astrology calendar

Mundane astrology looks at the sky over the world as a whole rather than at an individual. Its classical tools are the ingress charts cast when the Sun enters the cardinal signs at the equinoxes and solstices, eclipses, the slow planets changing sign, and the 20-year cycle of Jupiter and Saturn that Abu Ma’shar used to mark eras. This page lists them for the year and city you choose.
