This is a study aid. Enter your birth date, time and place and the years you want to look at, and the tool lists the planets the tradition points to when it discusses marriage in your chart, the dasha periods those planets run in that span, and the times Jupiter passes over or aspects your 7th house, your 7th lord or Venus. It shows where the two kinds of pointer overlap, and its first line names the first such period and the first overlap. It does not predict a marriage, and many such periods pass without one.
How it works
The pointers come from one textbook, so that each has a named source: P.V.R. Narasimha Rao, Vedic Astrology: An Integrated Approach (2000).
- Venus, the natural significator of marriage, for men and women alike (ch. 8.3).
- The lord of the 7th house of the navamsa (D9): Rao gives “the period of the 7th lord in D-9 can give marriage” as an example of how dashas work (ch. 16.5.1).
- The lord of the 7th house of the birth chart, and any planet in the 7th: the pointers the literature commonly names, as Rao records them (ch. 33.3).
- Jupiter in transit occupying the 7th house, the sign of the natal 7th lord or the sign of natal Venus, or aspecting one of them by its 5th, 7th or 9th sign aspect (ch. 25.3).
The tool builds your chart from the NASA JPL DE440 tables used across this site, in the sidereal zodiac with the Lahiri ayanamsa and whole-sign houses, and the navamsa by the Parashari rule. It then lists every Vimshottari sub-period (antardasha) in the span whose main period or sub-period belongs to one of the pointers. The dasha dates are the same as on our Mahadasha calculator. Jupiter’s changes of sign are taken from the same tables, exact to the second, and each of its stays in a sign is checked against the three points.
Reading the result
The first line names your pointer planets, the first dasha period in the span that involves one of them, and the first stretch where such a period overlaps with Jupiter touching your 7th house, its lord or Venus. The answer below it names the pointers again and counts the periods and Jupiter stays in the span. The first table gives each pointer and why it is one. The next lists the dasha periods, with which planet makes it a pointer, the main period, the sub-period or both. The Jupiter table gives each sign Jupiter is in during the span and what it occupies or aspects there. The last table shows where a pointer period and a Jupiter pointer run at the same time.
Read these as the places the tradition looks, not as dates. A period gives what the whole chart promises, so the same pointer can bring an engagement, a new partnership in work, or nothing visible at all. Rao himself warns that if one keeps adding conditions of this kind, such as the 7th lord, planets in or aspecting the 7th, their dispositors and so on, every planet ends up on the list and any past date can be explained (ch. 33.3). That is why this tool keeps to a few pointers, each with its source.
Where traditions differ
Some astrologers read the 7th from Jupiter instead of the 7th from Venus; Rao uses Venus in men’s and women’s charts alike (ch. 8.3), and this tool follows him. Rao also times marriage with sign-based dashas such as Narayana dasha, with the Upapada lagna and with Tajaka annual charts, and in his worked examples he weighs the strength of the candidate planets; none of these is done here. Aspects are read by whole signs, with Jupiter’s three full aspects, as in Rao’s transit examples.
What it does not do
It does not predict when, or whether, you will marry. It does not judge the strength of the pointers, look at the navamsa beyond its 7th lord, or use the Upapada, Narayana dasha or vivaha saham. It does not match two charts; for that see kundli matching. It needs the time of birth, because the 7th house and the navamsa depend on the rising sign. Births and dates from 1900 to 2074 can be entered, for up to 20 years at a time.

Frequently asked questions
↳ Can this tool tell me when I will marry?
No. It lists the periods and transits that the tradition looks at when it discusses marriage, each with its source. Many of these periods pass with no wedding, and the whole chart decides what a period brings.
↳ Why is Venus always on the list?
Venus is the natural significator of marriage. Rao uses it for men and women alike, so the tool includes it in every chart.
↳ What is the 7th lord?
The planet that owns the sign of your 7th house, counted from your rising sign. The 7th house is the house of partnership and marriage. The tool also uses the 7th lord of the navamsa, the chart Rao reads for marriage.
↳ Why does Jupiter matter?
In Rao's account of transits, Jupiter occupying or aspecting the 7th house, the 7th lord or Venus may give marriage. Jupiter aspects the 5th, 7th and 9th signs from the one it is in, so it can touch these points from several signs.
↳ What if no period overlaps with Jupiter?
Nothing is missing. The overlap is only the place where two kinds of pointer meet in time. Try a longer span, and remember that this is a study aid, not a forecast.
↳ Do I need my birth time?
Yes. The 7th house and the navamsa both depend on the rising sign, which changes with the time of birth.
