Erecting The Natal Chart
Once the astrologer has ascertained the exact time and place of the subject's birth, the local standard time (adjusting for any daylight saving time or war time) is then converted into Greenwich Mean Time or Universal Time at that same instant. The astrologer then has to convert this into the local sidereal time at birth in order to be able to calculate the ascendant and midheaven. The astrologer will next consult a set of tables called an ephemeris, which lists the location of the sun, moon and planets for a particular year, date and sidereal time, with respect to the northern hemisphere vernal equinox or the fixed stars (depending on which astrological system is being used). The astrologer then adds or subtracts the difference between the longitude of Greenwich and the longitude of the place in question to determine the true local mean time (LMT) at the place of birth to show where planets would be visible above the horizon at the precise time and place in question. Planets hidden from view beneath the earth are also shown in the horoscope.
The horoscope is then divided into 12 sectors around the circle of the ecliptic, starting from the eastern horizon with the ascendant or rising sign. These 12 sectors are called the houses and numerous systems for calculating these divisions exist. Tables of houses have been published since the 19th Century to make this otherwise demanding task easier.

Famous quotes containing the words erecting and/or chart:
“In America the taint of sectarianism lies broad upon the land. Not content with acknowledging the supremacy as the Diety, and with erecting temples in his honor, where all can bow down with reverence, the pride and vanity of human reason enter into and pollute our worship, and the houses that should be of God and for God, alone, where he is to be honored with submissive faith, are too often merely schools of metaphysical and useless distinctions. The nation is sectarian, rather than Christian.”
—James Fenimore Cooper (1789–1851)
“Perhaps in His wisdom the Almighty is trying to show us that a leader may chart the way, may point out the road to lasting peace, but that many leaders and many peoples must do the building.”
—Eleanor Roosevelt (1884–1962)
