How do you calculate Whole Sign houses?

Take the sign of the Ascendant and make that entire sign the 1st house, starting at 0 degrees of the sign. Each following sign becomes the next house in zodiacal order. The Ascendant degree still matters for other judgments, but it does not start the house.

How is Whole Sign different from Placidus?

Whole Sign assigns one complete zodiac sign to each house. Placidus divides the sky by time and can split signs across house cusps, especially at high latitudes. Traditional Hellenistic techniques such as profections and house rulership were built around Whole Sign.

Do I need my exact birth time?

You need a rising sign. If you already know it, this calculator can map the twelve houses immediately. If you do not, use the free natal chart with birth date, time, and place. Without a time, the rising sign and houses are not reliable.

What Whole Sign houses are

In Whole Sign houses, the sign on the Ascendant becomes the entire 1st house, from 0 degrees to the end of that sign. The next sign is the 2nd house, then the 3rd, and so on around the zodiac. Houses and signs line up one to one. A sign is never split across two houses.

The Ascendant degree still matters. It is the rising point, and traditional texts use it for other judgments. It does not start the house. If 4 degrees Leo is rising, all of Leo is the 1st house, not the slice from 4 degrees Leo forward.

1st house

The rising sign itself: body, temperament, and how the life presents.

House ruler

The traditional planet that rules the sign on that house. Its condition tells you how the topic tends to go.

Planets in the house

A planet in that sign is in that house. There is no cusp-splitting debate.

Why traditional charts use Whole Sign

Hellenistic techniques were written for this frame. Annual profections advance one Whole Sign house per year. House rulership is clean because each house has one sign and one traditional ruler. Placidus and other quadrant systems can put the 10th-house cusp in a different sign from the 10th Whole Sign house, which changes the year-ruler and the career testimony.

This site's natal calculator uses Whole Sign houses for that reason. The free reading is who you are and how your life has gone - no future predictions. Dated clocks belong in the optional source-cited analysis.

How to use the result

Note the sign and traditional ruler of the house you care about - 10th for career, 7th for partners, 2nd for resources.
Find that ruler in the natal chart: sign, house, dignity, and aspects.
Read the house topic through the ruler's condition, not through the house number alone.
