Muhurta Chintamani — Samvatsara-prakarana, Sun-avastha on Sankranti, verse 13Sun in Kimstughna karana described as 'urdhva' (upright, sama) — 'sama: shreshtha ihardhavarshane', i.e. neutral-to-mildly auspicious.
Vyatipata = (Sun + 4r 13°20') subtracted from 12 rashis — defined as 'a-prakasha-graha' (invisible graha).
Parashara Smriti — Madhaviya-vritti, Dana-kala-nirupana, Section on vyatipata as inauspicious yoga / sankrama (Islampurkar 1894 ed., around lines 40233-40259)Mahavyatipata defined; cited alongside ayana and vishuva as auspicious-dana times despite the yoga itself being inauspicious for new beginnings.
Narada Purana — Purvabhaga, Dvitiya-vrata section (Ashunyashayana-vrata), month-wise Dvitiya-vrata (Sankshipta ed., lines 65701-65750) — 'अशुन्यशयन ... चन्द्रमाके लिये अर्घ्यदान'Shravana-Krishna Dvitiya = Ashunyashayana-vrata to Vishnu-Lakshmi with chandra-arghya; Kartika-shukla Dvitiya = Yamadvitiya.
'Yam, Vishvedeva, Chandra, Brahma, Guru, Chandra, Indra, Jala, Sarpa, Agni, Surya, Bhumi, Rudra, Brahma, Varuna, Ganesha, Rudra, Kubera, Vishvakarma, Mitra...' -- Rudra is named twice (yoga 13 Vyaghata and yoga 20 Shiva); the Shiva-Yoga at index 20 derives its name from this lordship.
Bhavishya Purana — Uttara-parva, Chaturthi-vrata-kalpa (Angaraka-chaturthi-vrata-varnana), Chaturthi-vrata chapter (DLI Hindi ed., around lines 70101-70150)Krishna-Yudhishthira samvada on Chaturthi vrata including Angaraka Chaturthi.

Muhurta Chintamani — Shubhashubha Prakarana, varjya vara-nakshatra-tithi combinations, verses 20-21 (Pyarelal Mishra ed., lines 791-823)Classical text: Panchami-tithi + Hasta-nakshatra + Sunday = sarvakarya-varjya. Modern observance reads Hasta-Panchami as auspicious for Saraswati/skills — disagreement noted; classical source dominates per BPHS-first policy.
Lists 28 anandadi yogas: 'siddhi' named explicitly as one yielding karya-siddhi by its own name (siddha-yoga is the 21st nitya-yoga).
Narada Purana — Purvabhaga, Anandadi-yoga section, Anandadi 28-yoga list (sankshipta ed., around lines 42101-42150)Siddhi yoga #19 in Anandadi enumeration; 'svanama-phaladayaka' — gives fruit per its name.

, verse 57 (Pyarelal Mishra Hindi ed., lines 2174-2196) — Sadhya not in the tyajya-list 'व्यतिपातवैधृति... परिघव्यावातगण्डयोग ... विष्टि ...'
Sadhya is conspicuously absent from the canonical 6-ninda-yoga list (vyatipata, vaidhriti, parigha, vyaghata, ganda, vajra), placing it among shubha-yogas — 'achievable goals' interpretation follows the literal 'sadhya' (to be accomplished).
— Prakriti Khanda (Shashthi-devi mahatmya)
, Shashthi-stuti section (devi identified as Kartikeya-pranapriya)
Both adhyayas prescribe Saptami-tithi as the supreme day for Surya worship using the twelve-name list (Bhanu/Arka/Ravi/Brahma/Surya/Shakra/Hari/Shiva/Shriman/Vibhavasu/Tvashta/Varuna).
Bhavishya Purana — Brahma Parva, Saptami-kalpa (Akshyanga Saptami adhyaya 111), opening versesBhavishya Purana's Saptami-kalpa is the standard nibandha source for Bhanu/Ravi-Saptami; Sunday + Saptami amplifies it.

Brahma listed at position 25 of the Anandadi yogas; each yoga is said to give 'svanama-sadrsha phala', so Brahma yoga gives creative / spiritual / Brahma-loka phala.
Shiva Purana — Kotirudra-samhita, Tandi Sahasranama prelude, verses 47-48Tandi (a brahma-yogi) is named as the composer of the Shiva Sahasranama in brahma-yoga — establishes the spiritual-creative significance of the yoga.
Narada Purana — Uttarabhaga, Ekadashi-vrata-mahatmya (Rukmangada-Mohini samvada), Rukmangada vrata-pratijna (Sankshipta ed., lines 76451-76550) — 'एकादशीके दिन भोजन कैसे करूँगा ... मधुसूदनके पुण्यमय दिवस एकादशीको अन्नका सेवन नहीं करूँगा'King Rukmangada's vow never to take food on Ekadashi establishes the canonical fasting rule; Thursday (Guru/Vishnu's vara) intensifies the merit.
