Frequently asked questions

A birth chart can look different for a number of reasons - usually, it does so because a different astrological technique was used. The basic information remains the same while a different system can make the drawing look different.
Hindu systems, for example, are based on sidereal astrology, which causes shifts in the planets and ascendant. The interpretation can be different as well.
Sometimes errors are made - the calculation could be wrong, perhaps the wrong place or time zone were used. Please check your data! With a given set of data, there can be no ambiguity. The result you get at Astrodienst is correct. Our calculations for astronomical facts are the most reliable in the whole "industry". For further reference, please see the "Full Documentation" of the Swiss Ephemeris.

The colours of the aspects show which kind of aspect group they belong to.
Red aspects belong to the group of "analytical" or "disharmonious" aspects (the main ones are Square and Opposition), blue ones are considered "synthetic" or "harmonious" (Sextile and Trine), and green is used for the minor aspects of Quinkunx and Semisextile.
For more information on the aspects used in our charts, please read the respective chapter in our Introduction to Astrology.

It is unnecessary because the South Node is always 180° opposite the North Node (which is given).
However, there is an option to add the South Node to your chart drawing. Go to "Free Horoscopes" > "Extended Chart Selection" and scroll down to the section "Display and Calculation Options" and tick the box "Descending Node".
