To prepare the Mundane horoscope the time of the entry of the Sun into the zodiac as Aries, Taurus, Gemini etc is Marked. and the other planets are placed as per the transit. The most important aspect in the Mundane Astrology is the planetary Cabinet changing every year. All seven planets become King, prime minister, commander-in-chief, lord of vegetation, lord of minerals, lord of juices, lord of Grains, etc. These offices will be changing every year. The planet that becomes the king in one year becomes prime minister in the next year then commander-in-chief and so on.

The Sun and the Moon are the royal planets, if they don’t become the king then during that year royality greatly suffers. In the same way Mars is the commander-in-chief and if in any year Mars is not as Commander- in- chief then that year the army and navy of that nation or state suffers.

The appearance of eclipses will find manifestation in the country through which it passes. Two eclipses one solar and one lunar occurring within 14 days indicate National troubles like assassinations, war activities, etc. 

The appearance of comets and the direction should also be considered in Mundane Astrology. The Zodiac in which the comet appear suffers and the health of the people of that nation are affected.

Mundane Astrology is a very useful branch of Astrology and the predictors must be careful in venturing predictions.
