What Is the Shodasamsa (D16) Chart?

Each sign is divided into sixteen equal parts. A movable sign’s division starts counting from Aries, a fixed sign’s from Leo, and a dual sign’s from Sagittarius — the same modality-based starting-sign logic used by several divisional charts, applied here to a finer, sixteen-part division.

Reading Vehicles and Comforts From the D16

Classical texts read the D16 for the ease and quality of material comforts — vehicles historically, but by extension the general physical conveniences and pleasures available to a person — alongside the D1 chart’s own indicators for the same themes.

A Less Commonly Consulted Chart

Compared to the D9 or D10, the D16 is consulted less frequently in modern practice, but it remains part of the classical shodashavarga (sixteen-chart) system and is included here for completeness and for astrologers who do work with it.

Shodasamsa Chart Calculator (D16) FAQs

What is the Shodasamsa (D16) chart used for?

Studying vehicles, general material comforts, and physical happiness — how much ease and convenience a person experiences in daily life.

How is the D16 different from other divisional charts?

It uses a sixteen-part division of each sign with a modality-based starting rule (movable→Aries, fixed→Leo, dual→Sagittarius), distinct from the D9 or D10’s own rules.

Is the D16 as commonly used as the D9?

No — it’s consulted less often in modern practice, though it remains a recognized part of the classical divisional-chart system.

Does "vehicles" here mean literally cars?

Historically, yes — but the theme is usually read more broadly as material comforts and conveniences in general.

Do I need an accurate birth time?

Yes — the D16 Lagna depends on your D1 Lagna, which requires a precise birth time.
