Chinese Almanac MCP vs Telugu Calendar Utilities

get_panchangam

Returns full Panchangam JSON for a date and city: Pancha Anga (Tithi, Nakshatra, Yoga, Karana), sky events (Sunrise, Sunset, Moonrise, Moonset), auspicious windows (Brahma Muhurta, Abhijit, Amrita Kalam), inauspicious windows (Rahu Kalam, Gulika, Yamagandam, Varjyam, Durmuhurtham), Choghadiya, special day flags, and field-group provenance states. New in 1.9.0: ghati_clock (sunrise-anchored ghati/vighati clock), nakshatra_pada (Moon's pada 1-4), vishaghati windows, bhadra_mukha/bhadra_puchha (Vishti split), sankramana_avoidance, in_panchaka_nakshatra, nakshatra_mukha (Adho/Urdhva/Tiryak), anandadi_yoga, is_khar_maasa/khar_maasa_name, is_pitru_paksha, simha_stha_guru/simha_stha_shukra (Drik only), guru_maudhya/shukra_maudhya (Drik only), disha_shoola_direction, panchaka_rahita. Args: date=YYYY-MM-DD, city=city name (or pass latitude+longitude for a custom location; timezone is derived if omitted), system=drik|surya_siddhanta|vakya (default: drik), ayanamsa=lahiri|raman|krishnamurti|true_chitrapaksha (default: lahiri; SS and Vakya accept the param for API symmetry but always use their own mean-motion model).

get_muhurta

Returns auspicious and inauspicious time windows for a date and city as JSON. Lighter than get_panchangam — use for quick 'is this a good time?' queries. Includes field-group provenance and all 1.9.0 timing fields: vishaghati, bhadra_mukha/bhadra_puchha, sankramana_avoidance, ghati_clock, in_panchaka_nakshatra, nakshatra_mukha, anandadi_yoga, is_khar_maasa, is_pitru_paksha, simha_stha_guru/shukra, guru_maudhya/shukra_maudhya, disha_shoola_direction, panchaka_rahita. Args: date=YYYY-MM-DD, city=city name (or pass latitude+longitude; timezone is derived if omitted), system=drik|surya_siddhanta|vakya (default: drik).

get_special_days

Returns a JSON list of special days in a given month: Ekadashi (fasting days), Amavasya (new moon), Pournami (full moon), Pradosham, Sankranti, and Eclipses. Args: year=e.g. 2026, month=1-12, city=city name (or pass latitude+longitude; timezone is derived if omitted), system=drik|surya_siddhanta|vakya (default: drik).

get_daily_horas

Returns 24 planetary hours (horas) for a date and city as JSON. The 12 daytime horas start at sunrise and the 12 nighttime horas start at sunset. The first hora is ruled by the weekday lord. Args: date=YYYY-MM-DD, city=city name (or pass latitude+longitude; timezone is derived if omitted), system=drik|surya_siddhanta|vakya (default: drik).

get_lagna_transitions

Returns Ascendant (Lagna) sign boundaries for a date and city as JSON, tracking the rising sign on the eastern horizon from sunrise to next sunrise. Args: date=YYYY-MM-DD, city=city name (or pass latitude+longitude; timezone is derived if omitted), system=drik|surya_siddhanta|vakya (default: drik).

get_panchangam_range

Returns a compact Panchangam summary for each day in a date range (max 31 days). Each day includes: Tithi, Nakshatra, Yoga, Sunrise/Sunset, all auspicious and inauspicious windows, eclipse (if any), special yogas, and special day flags. New in 1.9.0: each day also carries all timing-computation fields — ghati_clock, nakshatra_pada, vishaghati, bhadra_mukha/bhadra_puchha, sankramana_avoidance, in_panchaka_nakshatra, nakshatra_mukha, anandadi_yoga, is_khar_maasa/khar_maasa_name, is_pitru_paksha, simha_stha_guru/shukra, guru_maudhya/shukra_maudhya, disha_shoola_direction, panchaka_rahita. Useful for planning muhurtas over a week or comparing multiple days. Args: start_date=YYYY-MM-DD, end_date=YYYY-MM-DD, city=city name, system=drik|surya_siddhanta|vakya (default: drik), ayanamsa=lahiri|raman|krishnamurti|true_chitrapaksha (default: lahiri).

get_combustion_calendar

Returns Asta (heliacal setting / combustion entry) and Udaya (heliacal rising / re-emergence) periods for the five classical planets — Mercury, Venus, Mars, Jupiter, Saturn — over a date range for a given city. Asta marks when a planet becomes invisible due to proximity to the Sun; Udaya marks when it re-emerges. This matches the Drik Panchang Asta/Udaya calendar (sky-visibility criterion), not the fixed BPHS elongation Maudhya thresholds used in per-day combustion flags. Accuracy: within 1–2 days of Drik Panchang for most planets; Mars ±2 days. Max date range: 366 days. Args: start_date=YYYY-MM-DD, end_date=YYYY-MM-DD, city=city name (or pass latitude+longitude; timezone derived if omitted), planets=optional subset e.g. ['Saturn', 'Jupiter'] (default: all five).

get_graha_yuddha

Returns Graha Yuddha (planetary war) periods in a date range. A planetary war occurs when two of the five tara grahas — Mercury, Venus, Mars, Jupiter, Saturn — come within 1° of each other in ecliptic longitude. The planet with the higher ecliptic latitude (more northerly) at the closest approach is the victor; the vanquished loses astrological strength for the duration. The Sun, Moon, Rahu, and Ketu are exempt by classical convention. Each war entry includes: the two planets, winner, loser, start/exact/end times in UTC, and minimum separation in arc-minutes. Max date range: 366 days. Args: start_date=YYYY-MM-DD, end_date=YYYY-MM-DD, planets=optional subset e.g. ['Venus', 'Jupiter'] (default: all five, yielding all 10 pair combinations).

get_rashi_ingresses

Returns all rashi (sign) ingress events for the classical planets over a date range. A rashi ingress is when a planet crosses from one zodiac sign into the next — the foundational event for gochara (transit) period boundaries. Sidereal coordinates (ayanamsa-configurable). Includes retrograde ingresses (a planet re-entering a sign it recently left). Each entry has: planet, rashi entered, enters (UTC), exits (next ingress, UTC — may fall outside the range). Planets with no sign change in the range (e.g. Saturn in Meena all of 2026) do not appear. Supported planets: Sun, Mercury, Venus, Mars, Jupiter, Saturn, Rahu, Ketu. Moon is excluded (too frequent — a sign every ~2.25 days). Max range: 366 days. Args: start_date=YYYY-MM-DD, end_date=YYYY-MM-DD, planets=optional subset (default: all eight), ayanamsa=lahiri|raman|krishnamurti|true_chitrapaksha (default: lahiri).

get_eclipse_calendar

Returns all solar and lunar eclipses in a date range with per-city visibility and Sutak timing. Each eclipse entry includes: kind (Solar/Lunar), subtype (Total/Annular/Partial/Penumbral), visible (whether it is observable from the given city), start/end times in local time, and sutak (ritual impurity window — 12 hours before Solar, 9 hours before Lunar) for visible eclipses only. Max range: 730 days (two years). Args: start_date=YYYY-MM-DD, end_date=YYYY-MM-DD, city=city name (or pass latitude+longitude; timezone derived if omitted).

get_panchanga_shuddhi

Panchanga Shuddhi — five-limb purity assessment for any date. Returns a verdict (Sarva Shuddha / Chatushka Shuddha / Tri Shuddha / Dvi Shuddha / Eka Shuddha / Sarva Ashuddha) and a per-limb breakdown (Tithi, Vaara, Nakshatra, Yoga, Karana) with quality ('shuddha' | 'ashuddha' | 'mixed') and a one-line reason for each. Rules: Tithi — Rikta (4th/9th/14th) are ashuddha; Vaara — Mon/Wed/Thu/Fri are shuddha, Sun/Tue/Sat are ashuddha; Nakshatra — Laghu/Mridu/Dhruva/Chara are shuddha, Tikshna/Ugra are ashuddha, Krittika/Vishakha are mixed; Yoga — the 17 Nitya auspicious yogas are shuddha, Vyatipata/Vaidhriti are ashuddha, partial-dosha yogas (Vishkambha/Atiganda/Shoola/Ganda/Vyaghata/Parigha) are mixed; Karana — Vishti (Bhadra) and the four fixed karanas are ashuddha, all movable karanas are shuddha. Values are taken at sunrise. Args: date=YYYY-MM-DD, city=city name (or latitude+longitude), system=drik|surya_siddhanta|vakya (default: drik).
