How we build a forecast

Our forecast is not a sign horoscope and not a guess. It follows the Parashari school, and its timing follows K. N. Rao: the chart shows what is promised, the dasha shows when the theme opens, the transits of Jupiter and Saturn show when the conditions meet. Below is each step, what depends on your birth time and what a program cannot do.

In short

  • Only the nine grahas of Jyotish and classical Parashari rules; timing as K. N. Rao teaches it.
  • The chart promises, the dasha opens the theme, the double transit of Jupiter and Saturn switches it on.
  • A forecast gives windows of months, not the date of an event.
  • The house of the event names its theme: the 7th partnership, the 10th career, the 4th home.
  • How precise a window is depends on the birth time; we check how sensitive your chart is to it.
  • In a difficult personal case a program does not replace a living astrologer.

An example chart, calculated by the engine: lagna Pisces, the 7th house Virgo, its lord Mercury. Jupiter and Saturn both touch the 7th house November 2027 — February 2028, in the period of Mercury (sub-period of Venus); the dots are the days Mars starts to touch the house.

A forecast in five steps

  1. The chart. Calculate the sidereal chart; find the house of the theme, its lord, the planets in it and their strength.
  2. The dasha. Find the Vimshottari periods whose lords are linked to that house.
  3. The double transit. Inside those periods, find the months when Jupiter and Saturn both influence the house or the sign of its lord.
  4. The fast planets. Inside the window, the Moon, the Sun, Mars and the panchanga mark the days that suit action.
  5. The theme and the year. Read the window by its house; for a forecast of a year, add the annual chart (varshaphala).

1. The birth chart: what is promised

We calculate the sidereal chart with whole-sign houses: the whole sign of the lagna is the 1st house (how exactly we calculate is on the page how we calculate and write). For the theme of the question we look at its house, the lord of that house, the planets placed in it and their strength: dignity, shadbala, combustion. The chart sets the limits: a transit does not create an event the chart does not promise, timing only says when.

2. The dasha: when the theme opens

The main clock is the Vimshottari dasha: 120 years shared among the nine planets, each period divided into antardashas. A theme becomes active when the lord of the mahadasha or antardasha is linked to its house: it rules the house, stands in it or is its karaka (Venus for partnership, the Sun and Saturn for career, the Moon for home). Yogas work the same way: a yoga gives its result in the periods of the planets that form it; only the Nabhasa yogas act in every period (BPHS 35).

3. The double transit of Jupiter and Saturn

Inside the period, the months are found by the double transit as K. N. Rao teaches it: an event of a house is timed when transiting Jupiter and Saturn both influence that house or the sign holding its lord, by standing there or by full aspect (Jupiter aspects the 5th, 7th and 9th signs from itself, Saturn the 3rd, 7th and 10th; BPHS ch. 26). Either planet alone touches a given house about a third of the time and times nothing; the two together are rarer and mark a window. A contact shorter than two weeks is not counted as a window. The window is stronger when the dasha running at its start is linked to the house.

4. The fast planets: the moment inside the window

Jupiter and Saturn give the months. Inside them the moment is set by the fast planets — the Moon, the Sun and Mars — and by the panchanga of the day. They belong to the daily and weekly forecast, where they mark the days when it is easier to act. In a forecast for months and years we deliberately leave them out: a planet that changes sign within days or weeks says nothing about a year.

5. The house names the theme, the annual chart refines the year

What a window is about is decided by its house: the 2nd — money and family, the 4th — home and moving (with the 12th for living abroad), the 5th — children, the 7th — the partner and marriage, the 10th — career. For a forecast of a year we also build the annual chart of the Tajaka system, the varshaphala: the chart of the Sun's return to its birth position, with the lord of the year and the muntha. It shows which themes the year brings to the front.

What depends on the birth time

The dashas are counted from the Moon's degree: an hour of error moves their boundaries by months. The houses depend on the lagna, which changes sign about every two hours, and the navamsha changes far more often. So for every chart we calculate how many minutes of error move the lagna of the birth chart and of the D9, D10 and D60 into another sign; a conclusion that rests on such a sensitive chart is marked. If the time is uncertain, rectification helps: candidate times are compared with the dates of events in your life.

A birth near a sign boundary: at 15:30 the lagna is Sagittarius 29°46′, at 15:45 it is already Capricorn 3°40′. The 1st house changes, and with it every house of the chart.

What a program does not replace

The calculation is exact and the rules are classical, but a forecast is a window of likelihood, not a date and not a guarantee: decisions and circumstances remain yours. A program applies the same rules to every chart; a person notices what does not fit into rules. In a difficult personal case — a crisis, health, a choice where much is at stake — talk to a living astrologer and, where needed, a doctor, a lawyer or a psychologist.

Questions

Why only nine planets?
Classical Jyotish works with the seven visible planets and the lunar nodes Rahu and Ketu, and its timing rules were written for them. We do not add planets or techniques from other systems.
Can you name the exact date of an event?
No. We name windows of months when the conditions meet. Inside a window the daily forecast shows the days that suit action, but the event itself depends on people and circumstances.
Does the AI invent the reasons for a window?
No. The dasha, the transits and the window are calculated by the engine; the language model only puts them into words, and the answer names the period and the transits it rests on.
What if I do not know my birth time?
Without the time the houses are uncertain, so timing by houses is unreliable. Rectification helps to narrow the time by the events of your life.
