FAQ

What kind of astrology do you use?

We respect every traditional astrological system, but we choose to base our astrological calculations on Western astrology. The calculations are powered by the Swiss Ephemeris.

How does 12andus calculate the reports?

12andus' astrological reports are calculated by accurately weighing hundreds of astrological elements for each individual person. We consider every planet's positions, aspects, and houses, as well as the subtle relationships between them. We weigh all of these elements and use a proprietary method to infer a person's qualities, traits, relationship qualities, and forecast future qualities and attitudes.

It seems you give more importance to inner qualities and states rather than the facts of life.

Astrology is more about inner states than actual events. Unfortunately, popular astrology has altered this by focusing on events, which are actually the effects of inner states. If your inner states, for instance, are about being mellow and romantic, then there are more chances for you to find a lover. Thus, we concentrate on your inner states, which are the root of your external life events.

If I don't know my birth time, are the astrological reports still accurate?

We work hard to give you the best possible report even in the case of an unknown birth time, but be aware that in such a case, some astrological elements will be missing, specifically the 12 houses and the accuracy of the moon position. Those are important elements of a personalized horoscope, so the reports will be less accurate.

What about typical horoscopes based solely on the sign?

There's absolutely no astrological value in that. The "sign" is only the position (not even precise to the degree) of the Sun, which is one among many elements of a horoscope. Astrology works only when it is personalized with a person's birth data.

How many people's birth data can I input on 12andus? I have many friends, family members, and ex-partners I wish to know about.

As a free member, there's a limit of 50 people. As a Premium member, there's no limit.

Is the birth data I input kept private?

Yes, it is. However, your own birth data, the one you set in your profile, will be shared, but only with 12andus members you choose to befriend.

How are personalized astrological reports different from generic sign astrology?

The "sign" is the position of the Sun in the zodiac at birth. While the Sun is an important element, an astrological reading considers the planets, nodes, 12 houses, and the complex interactions between them. Furthermore, personalized astrology evaluates the exact position of the Sun at birth, while generic signs don't. A Sun placed at the beginning of a sign may experience very different aspects with other planets than a placement at the end of the same sign. In other words, generic sign astrology is inaccurate, incomplete, and most of the time just off-target.
