# Dashas: Panchottari Mahadasha

`POST /vedic/dashas/panchottari/maha`

## Request

- Base URL: `https://api.astroway.info/v1`
- URL: `https://api.astroway.info/v1/vedic/dashas/panchottari/maha`
- Auth: API key in header `X-Api-Key`
- TypeScript: <https://skmtc.dev/astroway/apis/astroway-calculation-api/docs/vedic/dashas/panchottari/maha/post.ts> (a function with typed inputs; its response is checked against the schema)

Panchottari Dasha, 105-year nakshatra cycle of 7 lords. BPHS 46.29-31: the stars from Anuradha to the birth star, divided by 7, give the first lord; Sun 12, Mercury 13, Saturn 14, Mars 15, Venus 16, Moon 17, Jupiter 18 years (Rahu and Ketu left out). Given for a Cancer lagna in an amsha of the Sun: `initial.applicable` reports the navamsa and the dwadashamsa reading, the periods are computed either way.

## Query parameters

- `fields` string
- `precision` integer

## Headers

- `Idempotency-Key` string

## Request body

- DashaInput: Birth data for a single natal chart. Required: date (YYYY-MM-DD), time (HH:mm:ss), latitude and longitude in decimal degrees. The short forms lat, lon, lng and tz are rejected with 400 INVALID_FIELD; pass the full names. timezoneOffset is hours from UTC and defaults to 0, meaning UTC; send timezone instead (an IANA name such as Europe/Kyiv, or auto) and the offset for that date is worked out, summer time included. city is a display label only: nothing here geocodes it, so it never stands in for coordinates. houseSystem is a single house-system letter, P by default; a name such as "Placidus" is refused, and the case matters because I and i are two different Sunshine systems.
  - `date` string, required
  - `time` string, required
  - `timezoneOffset` number, nullable: Hours from UTC at the given moment, not minutes. Fractional zones are hours too: 5.5 for India, 5.75 for Nepal, -3.5 for Newfoundland. Defaults to 0, meaning UTC. Ignored when timezone is sent.
  - `timezone` string: IANA zone name such as Europe/Kyiv, or auto to look the zone up from latitude and longitude. The server takes the offset that zone kept at this local date and time, summer time included, and uses it in place of timezoneOffset. A clock time that happened twice takes the first occurrence; one skipped when clocks went forward takes the offset from before the change. Abbreviations such as EST are refused. Before 1970 the tz database is not reliable for every place, so send timezoneOffset when the local clock is known.
  - `latitude` number, required
  - `longitude` number, required
  - `houseSystem` 'P' | 'K' | 'R' | 'C' | 'E' | 'W' | 'B' | 'M' | 'O' | 'A' | 'T' | 'V' | 'D' | 'F' | 'G' | 'H' | 'I' | 'i' | 'L' | 'N' | 'Q' | 'S' | 'U' | 'X' | 'Y'
  - `name` string
  - `city` string
  - `zodiacType` 'tropical' | 'sidereal'
  - `ayanamsaId` number, nullable
  - `ayanamsa` 'fagan-bradley' | 'lahiri' | 'de-luce' | 'raman' | 'krishnamurti' | 'kp' | 'yukteshwar' | 'jn-bhasin' | 'true-citra' | 'djwhal-khul': Sidereal school by name. Lahiri when omitted. Equivalent to ayanamsaId; send either.
  - `cosmogram` boolean
  - `targetDate` string
  - `targetTime` string
  - `targetTzOffset` number, nullable
