Get divisional chart (Varga) - D2 to D60 Calculator

post_vedic_astrology_divisional_chart

Read-only

Calculate any Vedic divisional chart (Varga) from D2 Hora to D60 Shashtiamsa. Divisional charts divide each zodiac sign into smaller segments to reveal detailed insights about specific life areas: wealth (D2), siblings (D3), property (D4), children (D7), marriage (D9), career (D10), parents (D12), vehicles (D16), spirituality (D20), education (D24), strength (D27), misfortunes (D30), merit (D40), character (D45), and past life karma (D60). Based on Brihat Parashara Hora Shastra (BPHS) Shodasha Varga system. Detects Vargottama planets (same sign in D1 and selected chart).

Input Schema

TableJSON Schema

Name	Required	Description	Default
`date`	Yes	Birth date in YYYY-MM-DD format. Date determines planetary positions and nakshatra calculations for Vedic kundli (janam patri). Accurate birth date is essential for dashas, yoga calculations, and divisional charts (vargas).
`lang`	No	Response language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.	en
`time`	Yes	Birth time in 24-hour HH:MM:SS format. Time is CRITICAL for Lagna (Ascendant) calculation and house divisions. It changes every two hours roughly. Even minutes matter for accurate nakshatra pada and divisional chart (D9, D10) calculations. Without exact time, Lagna and house-based predictions will be incorrect.
`compact`	No	Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.
`ayanamsa`	No	Sidereal frame (ayanamsa) the chart is cast in. "lahiri" is Lahiri/Chitrapaksha, the traditional Vedic standard used by most software, and is the default. "raman" is the B.V. Raman ayanamsa from Hindu Predictive Astrology, about 1.45 degrees below Lahiri. "kp-newcomb" and "kp-old" are the two Krishnamurti Paddhati frames. "custom" takes your own value in degrees via ayanamsaValue, for reconciling exactly against a specific reference program. The frame rotates the whole zodiac, so a graha sitting within 1.45 degrees of a boundary can change rashi or nakshatra when you switch: pick the one your reference software uses and keep it.	lahiri
`division`	Yes	Divisional chart number. Each division reveals a specific life area. Supported: 2 (Hora, wealth), 3 (Drekkana, siblings), 4 (Chaturthamsa, property), 7 (Saptamsa, children), 9 (Navamsa, marriage), 10 (Dasamsa, career), 12 (Dwadasamsa, parents), 16 (Shodasamsa, vehicles), 20 (Vimsamsa, spirituality), 24 (Chaturvimsamsa, education), 27 (Bhamsa, strength), 30 (Trimsamsa, misfortunes), 40 (Khavedamsa, merit), 45 (Akshavedamsa, character), 60 (Shashtiamsa, past life karma).
`latitude`	Yes	Birth location latitude in decimal degrees. Location determines local sidereal time for Lagna calculation and affects bhava (house) cusps. Example: Delhi 28.6139, Mumbai 19.0760, Kathmandu 27.7172.
`timezone`	No	Timezone: an IANA name (e.g. "America/New_York", "Europe/London", or `cities[0].timezone` from /location/search) or decimal hours from UTC (e.g. -5 for EST, 5.5 for IST). An IANA name is resolved to the offset in force at the given date and time. Defaults to 5.5.
`longitude`	Yes	Birth location longitude in decimal degrees. Affects local time calculations and ayanamsha adjustments. Example: Delhi 77.2090, Mumbai 72.8777, Kathmandu 85.3240.
`ayanamsaValue`	No	Custom ayanamsa value in degrees. When provided, overrides the computed ayanamsa from the selected type. Use for testing with specific ayanamsa values or matching a particular reference source.

TDQS

A3.9/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations declare readOnlyHint=true and destructiveHint=false, so the description doesn't need to repeat that. It adds behavioral context by mentioning it is based on BPHS Shodasha Varga system and detects Vargottama planets, which is a specific feature. However, it doesn't disclose any other behavioral traits like computational specifics, limitations, or what happens with invalid inputs beyond the schema. It adequately supplements the annotations without contradicting them.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is moderately long but front-loads the purpose and immediately lists the divisions with their life areas. Each sentence contributes value, though the enumeration is verbose. It avoids fluff and uses a clear, structured list. It is efficient for the richness it conveys, warranting a 4 rather than a 5 due to its length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description need not explain return values. Given the complexity (10 parameters, 5 required, 2 enums), the description covers the key decisions (which division, what each means) and the astrological basis. All parameters are documented in the schema, so nothing essential is missing. It is complete for an agent to correctly invoke the tool, though it could mention edge cases like ayanamsa interplay, which is already in the schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description enhances the 'division' parameter by mapping each number (2, 3, 4, 7, 9, ...) to life areas (wealth, siblings, property, children, marriage, etc.), which provides meaning beyond the schema's simple enumeration. This helps agents understand which division to request. The description does not cover other parameters, but they are already well-documented in the schema, so the extra semantic value is sufficient for a 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool calculates any Vedic divisional chart (Varga) from D2 to D60, with a specific verb and resource. It enumerates the life areas for each division, distinguishing it from sibling tools like navamsa that focus on a single division. The purpose is unambiguous and not a tautology.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explains what the tool does and lists the life areas for each division, which helps select the appropriate division number, but it doesn't explicitly state when to choose this tool over alternatives like post_vedic_astrology_navamsa. There is no mention of when-not-to-use or comparison with siblings, leaving usage guidance implicit rather than explicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
