Shodashottari Dasha is a 116-year conditional nakshatra-based timing system of Jyotish, dividing a lifetime into eight planetary periods (mahadashas) whose lengths run 11, 12, 13, 14, 15, 16, 17, and 18 years and sum to 116. It is an udu (nakshatra) dasha named after its total span — Sanskrit shodasha (sixteen) plus uttara (more), sixteen more than a hundred — and it belongs to the conditional-dasha chapters of the Brihat Parashara Hora Shastra (BPHS), applied only when a birth meets a specific paksha-and-time rule rather than to every chart the way Vimshottari is.

The eligibility condition turns on the half of the lunar month and the time of birth. As translated in BPHS, Shodashottari is reckoned when the native is born by day in Krishna Paksha (the dark, waning half) or by night in Shukla Paksha (the bright, waxing half); an alternate formulation in the same chapters keys it to the Lagna falling in the hora of Chandra for a Krishna Paksha birth, or in the hora of Surya for a Shukla Paksha birth. Some modern commentators add the qualifier that the Lagna lord be strong before the scheme is preferred. Where translators differ, the paksha-plus-day-or-night rule is the most widely cited.

The eight period lords and their lengths are Surya 11, Mangal 12, Guru 13, Shani 14, Ketu 15, Chandra 16, Budha 17, and Shukra 18 — adding to exactly 116. The set carries eight grahas rather than nine: it admits Ketu but omits Rahu, the reverse of which node a scheme keeps being one of the diagnostic features that separates the conditional nakshatra dashas from one another. The ascending arithmetic run of lengths, each one year longer than the last, is the structural signature shared with its sibling conditional schemes such as the 112-year Dwadashottari and the 105-year Panchottari.

The starting point is set by counting nakshatras. BPHS instructs the astrologer to count from Pushya to the Janma Nakshatra — the asterism the natal Moon occupies — and to divide that count by 8; the remainder indicates which graha's mahadasha is running at birth. The twenty-seven nakshatras are mapped onto the eight lords in this counted order, so that Pushya marks the head of the sequence. The entry point inside that first period is proportional, as in the other udu dashas: the fraction of the Moon's nakshatra already traversed at birth marks how much of the opening mahadasha has already elapsed.

As with every Parashari graha dasha, the reading weighs the period lord against its placement in the birth chart, and each mahadasha subdivides into antardashas (bhuktis) running the same eight-graha order from the mahadasha lord, their lengths proportional to each lord's own allotment. A Shodashottari period is read descriptively — the well-placed lord is said to bring its significations and the matters of the houses it rules with clarity, the afflicted lord to bring them under strain — never as fixed fate. Because the scheme applies only to qualifying births, an astrologer reaches for it as a conditional cross-check alongside the universal Vimshottari rather than as a standalone replacement.

How It Is Read

Shodashottari belongs to the conditional nakshatra dashas of BPHS — the schemes Parashara reserves for charts that meet a specific birth rule rather than applying universally. Its distinctiveness is threefold. It is paksha-keyed: the eligibility hinges on the half of the lunar month crossed with day-or-night birth, tying the whole timing model to the relationship between the Sun and Moon at the nativity. It is an eight-lord scheme that keeps Ketu but drops Rahu, a node choice that distinguishes it from Ashtottari, which makes the opposite node choice — keeping Rahu and dropping Ketu. And it is counted from Pushya rather than from the Moon's own nakshatra lord, a different anchoring logic from Vimshottari. For a qualifying chart it gives an astrologer a second, independently-derived timing map to read against the default — and where two schemes both flag the same span, classical practice treats the agreement as a strengthening signal.

Connections

Shodashottari is read in contrast with the universal Vimshottari dasha: where Vimshottari applies to every chart and spans 120 years across nine grahas, Shodashottari spans 116 across eight and applies only to qualifying paksha-and-time births. Its nearest structural siblings are the other ascending-length conditional schemes — the 112-year Dwadashottari, applied for a Venus-navamsa Lagna, and the 105-year Panchottari, applied for a Karka Lagna — each built from a run of consecutive-integer period lengths but counted from a different nakshatra. It also sits beside the 108-year Ashtottari and the 100-year Shatabdika among the conditional udu dashas. Structurally distinct are the rashi-based Jaimini Chara dasha and the pada-based Kalachakra dasha, neither built from fixed planetary lengths. Within Shodashottari a reading depends on the period lord's strength and house rulership — the period of Shani in the tenth house reads differently from a weak Shani — and on the natal Moon's nakshatra, which together with the count from Pushya fixes the entire sequence.

Frequently Asked Questions

What is Shodashottari dasha?

Shodashottari dasha is a conditional nakshatra-based timing system of Jyotish spanning 116 years, dividing a lifetime into eight planetary periods of 11, 12, 13, 14, 15, 16, 17, and 18 years. The lords are Surya, Mangal, Guru, Shani, Ketu, Chandra, Budha, and Shukra — eight grahas that include Ketu but not Rahu. It is described in the conditional-dasha chapters of the Brihat Parashara Hora Shastra and applies only to births that meet a specific lunar-half-and-time rule, rather than to every chart the way Vimshottari does.

How long is the Shodashottari dasha cycle and do the periods sum to 116?

The full Shodashottari cycle is 116 years. The eight mahadasha lengths are Surya 11, Mangal 12, Guru 13, Shani 14, Ketu 15, Chandra 16, Budha 17, and Shukra 18, which add to exactly 116 — the name itself means sixteen more than a hundred. The lengths form a simple ascending run, each one year longer than the last, a structural signature it shares with the sibling conditional schemes Dwadashottari and Panchottari. When the cycle completes it restarts from the head of the sequence.

When is the Shodashottari dasha applicable?

Shodashottari is a conditional scheme, applied only to qualifying births. As translated in BPHS, it is reckoned when the native is born by day in Krishna Paksha, the waning half of the lunar month, or by night in Shukla Paksha, the waxing half. An alternate formulation in the same chapters keys it instead to the Lagna falling in the hora of Chandra for a Krishna Paksha birth or the hora of Surya for a Shukla Paksha birth. Some commentators add that the Lagna lord should be strong. Where translators differ, the paksha-plus-time rule is the most widely cited.

How is the starting Shodashottari dasha calculated?

The starting period is fixed by counting nakshatras from Pushya to the Janma Nakshatra — the asterism the natal Moon occupies — and dividing that count by 8. The remainder indicates which of the eight grahas holds the mahadasha running at birth, so Pushya marks the head of the sequence. The entry point inside that first period is proportional: the fraction of its nakshatra the natal Moon has already crossed marks how much of the opening mahadasha has already elapsed at the moment of birth.

How does Shodashottari differ from Vimshottari dasha?

Both are udu, or nakshatra-based, graha dashas, but Vimshottari is universal — reckoned for every chart across 120 years and nine grahas — while Shodashottari is conditional, spanning 116 years across eight grahas and applying only to qualifying paksha-and-time births. Shodashottari keeps Ketu but drops Rahu, and it counts from Pushya rather than from the lord of the Moon's own nakshatra. In practice an astrologer reads it as a second, independently-derived timing map alongside Vimshottari for an eligible chart, not as a replacement for the default system.
