Pre school classes on astrology

Well this is from a pre school level book that i am reading on astrology.

The Zodiac or Rasi Chakra is defined as a belt of the celestial sphere extending 9 degrees of the ecliptic (the apparent orbit path of the sun around the earth in a geo-centric scheme).

The movement of the Sun through the Zodiac comprises the month (Masa) and the point of time of sun’s entry is known as Sankramana.

The most basic and universal unit of time is the day or Dina, which extends to 24 hours. Multiples of these give us weeks, months and years. A day can be further divided into hours which in Indian astrology is Hora, and is equivalent to an hour which are ruled by the planets in the following order: Arka, Shukra, Budha, Chandra, Manda, Jeevo, Dharasuta Sun, Venus, Mercury, Moon, Saturn, Jupiter and Mars rule each hora in a cyclic order, which repeats itself.

A day comprises three cycles of seven horas each, plus three hora of the next cycle. According to Hindu astrology, a day always start at sunrise. For example - Sunday begins with the cycle sun, Venus at sunrise and after completing three cycles, the three hours left would be Sun, Venus, and Mercury. The next day starts with the fourth hora of the cycle, which is ruled by Moon, and hence the day is called Monday. Thus each day of the week is named after the planet ruling the first hora of that day at sunrise. A week, consisting of seven days, named after the planets is called Varam.

Apart from the 12 solar months, there are 12 lunar months called Masas named after the Nakshatra (star) in which the full moon occurs in each successive month.

The year, known as Samvatsara, has two sections of six months each known as Ayanas. The Northern declination of the Sun, when it appears to move between the signs of Makara and Mithuna is called Uttarayana. The southern declination when the sun appears to move between Kataka and Dhanus is called Dakshinayana.

A year is further divided into six seasons known as Ritus. The Seasons Two months of the year form one season.

A solar day starts from sunrise till next sunrise. A lunar day, known as the Thithi is calculated from the longitudinal distance between the sun and moon. There are 30 Thithis in a lunar month distributed over 360 degrees, thus each Thithi has a span of 12 degrees. There are 14 Thithis in the Shukla Paksha and 14 Thithis in the darker half with Pournamy and Amavasya being the other 2 days of the month.

Most of the above are more like a trivia to me. I started studying the basics and just got lost without a teacher. May be someday i will find a guru to learn.
