What is Kalachakra Dasa used for?

Kalachakra examines sign periods selected from the Moon’s nakshatra and pada. This implementation documents the sequence, balance and calculation variants. Its cycle length is not a prediction of a person’s lifespan, and this page does not infer a specialized prediction claim solely from that length.

Your result shows calculated time periods. Understanding what happens within a period requires the rest of the birth chart; this page does not generate a new personal prediction.

How Kalachakra Dasa is calculated

The implementation derives the lunar pada, sign sequence and paramayush, then resolves the first-period balance using the selected calculation variant.

Follow the calculation step by step

Calculate the natal positions from the person’s birth time and place, using the selected Ayanamsa. Check applicability: Applicable to all charts.
Use the resolved sign sequence and chart-dependent balance reported by this method. Planetary nakshatra-balance formulas must not be substituted for a sign-system rule.
The default variant is IteratedFirstDasa. Seven named variants are available through DasaOptions.Kalachakra; compare Method and Notes when reproducing another program.
Subperiods follow this sign system’s own sequence and equal-division rules where defined. Keep parallel tracks separate and do not substitute a nine-planet proportional formula.
Convert the resulting year fractions to dates using the reported year convention. This system defaults to MeanTropical. A sidereal solar year measures a full sidereal revolution of the Sun; a fixed 360-day year and a mean tropical year are different clocks. Published approximate month/day arithmetic can differ from exact solar-motion boundaries.

Read each result from its inclusive start to its exclusive end. The schedule is clipped to the supported span; its length is not a prediction of lifespan. Use the live date query for fine detail and the life timeline for an overview.

History and traditional context

The supplied Udu book does not establish this implementation’s Kalachakra rules. Its Moon-pada sequences and named variants are documented from recovered JHora calculation code. The name alone is insufficient evidence for an exact historical origin or agreement among editions.

When and how to use it

Use a reliable Moon position and verify the selected variant before comparing schedules. Read the resolved sequence, direction and cycle length rather than treating it as another Chara order. A cycle’s paramayush value describes this timing structure and is not a personal lifespan prediction.

Illustrative calculation and source limits

Input illustration, not a book case: each uniform nakshatra spans 13°20′ and contains four padas of 3°20′. Locating the Moon within that pada selects a sequence entry; it does not by itself provide the first balance. The chosen Kalachakra variant completes that calculation.

This arithmetic illustration is explanatory; it is not a recorded API response.

How Kalachakra works

Chart-dependent cycleMajor periods and subperiods

Traditional applicability

Applicable to all charts.

Your result will tell you whether this person meets the traditional selection conditions. You can still explore the periods when the conditions are not met.

Starting rule, durations and settings

Starting reference and balance

The implementation derives the lunar pada, sign sequence and paramayush, then resolves the first-period balance using the selected calculation variant.

Lord sequence and durations

The worked table below shows the actual chart sequence and dated durations. Chart-dependent sequences are not presented as fixed universal orders.

The default variant is IteratedFirstDasa. Seven named variants are available through DasaOptions.Kalachakra; compare Method and Notes when reproducing another program.

Calculation settings

DasaOptions.Kalachakra selects the calculation variant. The response reports the convention actually used. A system’s full cycle is not a prediction of a person’s lifespan.

Use Kalachakra with an AI assistant

Connect an MCP-compatible assistant to the free public MCP endpoint https://mcp.vedastro.org/api/mcp/public. Follow the MCP connection guide, initialize the MCP session, list the available tools, and call either tool below with system: "Kalachakra".

Replace the sample with the user’s actual birth location, local birth date (DD/MM/YYYY) and time (HH:MM, 24-hour). No saved-person ID or website account is required by these tools. Never invent missing birth details. The server resolves coordinates and date-specific offsets. Inspection times are local to the birth location, not the browser timezone.

The date tool defaults to levels 3 and midday; the life tool defaults to level 1. Both use Raman Ayanamsa. Moola requires level 1. Deep whole-life expansions can be very large: prefer a date query for fine detail. Read raw_dasa.DasaAtTime or raw_dasa.DasaForLife; check IsApplicable, ApplicabilityReason and YearConvention. Intervals include Start and exclude End. Life periods use response-local Id/ParentId; keep Sudarsana tracks separate. These are calculation results, not generated predictions.

A recorded Kalachakra example

Birth: 14:20 16/10/1918 +05:30, Bangalore (longitude 77.5833, latitude 12.9667), Raman Ayanamsa. The following are the first 4 major periods from the actual recorded response.

Resolved method: Kalachakra. Moon nakshatra pada selects the nine-sign sequence (IteratedFirstDasa).

Lord	Start	End (exclusive)
Gemini	1918-10-16T14:20:00+05:30	1924-06-21T15:06:21.3833983+05:30
Taurus	1924-06-21T15:06:21.3833983+05:30	1940-06-21T12:06:24.8393983+05:30
Aries	1940-06-21T12:06:24.8393983+05:30	1947-06-22T04:47:41.3513983+05:30
Sagittarius	1947-06-22T04:47:41.3513983+05:30	1957-06-21T14:55:13.5113983+05:30

Understand the responsePeriod fields, hierarchy and timestamps

04 / FROM JSON TO UI

One period model. No interpretation.

DasaForLife returns a single chronological Periods array. Each level defined by the system is present, up to the requested depth. Filter by Level to draw bands, or follow ParentId to build a tree.

Flat timeline

Level 1 = Mahadasa, 2 = Bhukti, 3 = Antaram, through level 8.

// Node.js
const bhuktis = result.Periods.filter(p => p.Level === 2);

Nested display

Ids are local to this response. A root has no parent; a child references its enclosing period.

Id 1 · Rahu · Level 1
├─ Id 2 · Saturn · ParentId 1
└─ Id 3 · Mercury · ParentId 1

Dasa period response fields
Field	How to use it
`Id / ParentId`	Response-local integer id and nullable parent id. Build relationships within this result; do not store them as permanent identifiers.
`Level`	Subdivision depth, 1–8. Systems that define no subperiods return level 1 only.
`Lord`	`{ Kind, Name }`. Kind is `Planet` or `Sign`; planetary systems and rasi systems share one shape.
`Start / End`	ISO timestamps with offset. Half-open intervals: [Start, End). The first period starts at birth; its natural beginning may be earlier.
`Track`	Null for single-track systems. Sudarsana returns three tracks: Lagna, Moon and Sun.

Metadata explains the calculation: System, Method, MethodReason, YearConvention, LifeSpanYears, IsApplicable, ApplicabilityReason and display-only Notes.

Point snapshots

DasaAtTime returns Levels with Level, Type, Lord, Start and End for the chain running at at.

Separate clocks

Ayanamsa sets zodiac positions. DasaOptions.YearConvention sets duration. Janma defaults to 360-day years; Chara and Kalachakra use mean tropical years; other selections use true sidereal solar motion.

API reference & advanced discoverySignatures, parameters and CheckDasaSystemApplicability

05 / API REFERENCE

Small methods. Explicit choices.

Signatures below use API wire names and server defaults. Python and Node.js retain PascalCase method names; Dart and Java use lowerCamelCase; Go retains PascalCase with a context first and an optional options struct.

DasaForLife

DasaForLife(birthTime, system = Vimshottari, depth = 3, options = null)

The whole system-defined life as one chronological Periods array.

Open example →

DasaAtTime

DasaAtTime(birthTime, at, system = Vimshottari, depth = 3, options = null)

The running chain at one moment, with the start and end of every level.

Open example →

CheckDasaSystemApplicability

CheckDasaSystemApplicability(birthTime)

Advanced discovery: every supported system, whether it applies to this chart, why, its life span and whether it defines subperiods.

Open example →

Parameters

Parameter	Required / default	Meaning
`birthTime`	Required	Time and birth location.
`at`	Required for DasaAtTime	Moment to inspect; must be inside the system's life.
`system`	Vimshottari	One of the 24 forms. Explicit choices are never silently replaced.
`depth`	3	Integer 1–8. Start with 1 or 2 for long spans.
`options`	null	`YearConvention`, plus Kalachakra, Shoola or Narayana Sama settings only for those systems.

Events charts use a separate path

LifePredictor and Events APIs keep their sampled time-slice evaluation. Dasa calls return raw periods and no interpretation; use the API builder for event/chart calls.

Questions about Kalachakra

When should I choose Kalachakra?

Applicable to all charts.

How is the first period selected?

The implementation derives the lunar pada, sign sequence and paramayush, then resolves the first-period balance using the selected calculation variant.

Can I request every subdivision?

Request depth 1–8; the response includes only levels defined by this system. Use a date query for deep detail without generating a whole-life expansion.

Which clock and options does this system use?

The default is MeanTropical. Ayanamsa controls zodiac positions, while DasaOptions.YearConvention controls durations. DasaOptions.Kalachakra selects the calculation variant.
