If it occurs on two successive days, it is to be observed on the second day. When does not occur on any day, it is to be observed on the day of the tithi, but widows and sannyasins would observe on the next-day.” p. 105 Not evaluated: The next-day observance for widows and sannyāsins, the Bengal avoidance of an ekādaśī joined to daśamī, and the Vaiṣṇava aruṇodaya rule belong to other traditions and are not applied. |
| Vināyaka Caturthī vinayaka-chaturthi | Every lunation Śukla Caturthī | madhyāhna | Unstated in the source | “The sukla caturthi in each month is called Ganesa caturthi or Vinayaka caturthi.

It is observed at madhyahna. The chief among them are caturthis of Bhadrapada and Magha. Similarly the krsna caturthi in each month is called Sankasta caturthi, to be observed on the day when the tithi is current at moonrise. It is called Angaraka caturthi if it falls on Tuesday.” p. 108 Not evaluated: It is called Aṅgāraka Caturthī when it falls on a Tuesday; the weekday is not tested. |

| Vaiśākhī vaishakhi | Sun enters Meṣa nirayana | the day, from sunrise | Cannot arise: an instant | “Mesadi — Cadaka puja (Bengal), Bahag Bihu (Assam), Cheiraoba (Manipur), Visu (T. C. State), Vaisakhi (on the samkramana day commencing from sunrise).” p. 106 Not evaluated: The other names in the row (Cadaka puja, Bahag Bihu, Cheiraoba, Visu) are regional observances and wait with the regional rows. |
| Makara Saṅkrānti makara-sankranti | Sun enters Makara nirayana | the day, from midnight | Cannot arise: an instant | “Makaradi — Makaradi snana, Magh Bihu (Assam), Tila samkranti, Pongal (S. India), Bhogi (S. India — on the day before Pongal), Mattu Pongal (S. India — on the day after Pongal).” p. 106 |
| Pongal S. India pongal | Sun enters Makara nirayana | the day, from the sunset before | Cannot arise: an instant | “Makaradi — Makaradi snana, Magh Bihu (Assam), Tila samkranti, Pongal (S. India), Bhogi (S. India — on the day before Pongal), Mattu Pongal (S. India — on the day after Pongal).” p. 106 Not evaluated: The rule that heads the solar festivals, the day "taken to begin from midnight" (p. 106), is not applied to Pongal. It is kept on the first day of the month of Makara as the Tamil districts count it, a transit after sunset going to the next day (p. 244); the Rashtriya Panchang prints Pongal so. |
| Bhogi S. India bhogi the day before Pongal | Sun enters Makara nirayana | the day, from the sunset before | Cannot arise: an instant | “Makaradi — Makaradi snana, Magh Bihu (Assam), Tila samkranti, Pongal (S. India), Bhogi (S. India — on the day before Pongal), Mattu Pongal (S. India — on the day after Pongal).” p. 106 |

India mattu-pongal the day after Pongal | Sun enters Makara nirayana | the day, from the sunset before | Cannot arise: an instant | “Makaradi — Makaradi snana, Magh Bihu (Assam), Tila samkranti, Pongal (S. India), Bhogi (S. India — on the day before Pongal), Mattu Pongal (S. India — on the day after Pongal).” p. 106 |
A row that names no part of the day falls under the preface: “Here noon or madhyahna relates to the period of time from 24 minutes (one ghatika) before mid-day upto the same time after it. This is the most appropriate time. If this time is not covered by the tithi on any day, the festival is to be observed on the succeeding day of the tithi.” The general rule the marks refer to: “When the requisite tithi covers the prescribed time on two successive days, the festival is to be observed in such a case on the first day where marked 'Purvaviddha', and on the second day where marked 'Paraviddha'.” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 101. Where a row marks neither, the resolver rules the day the tithi covers longer and flags the ruling as a boundary, because that choice is ours and not the source’s. A tithi within 300 seconds of a threshold is a boundary too.
The solar festivals are dated by the Sun’s entry into a sign: “The following festivals are observed according to the day of Sun's transit into rasis (Ravi-samkramana). For this purpose the day has been taken to begin from midnight, i.e., when the samkramana takes place after midnight, the festival relating to the samkramana is to be observed on the following day.” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 106. Pongal alone is not taken from midnight: its row tags it for South India, and it is ruled by the report’s account of how a Tamil month begins, “The Tamil rule: In the Tamil districts the rule is that when a samkranti takes place before sunset, the month begins on the same day, while if it takes place after sunset the month begins on the following day.” Calendar Reform Committee 1955, Rules of Samkranti, p. 244. A rule kept the day after or before another takes that rule’s day and counts from it.
Not here yet: rows kept in one region under a rule of its own (Bengal, and the regional names of the solar rows), rows dated by a nakṣatra in a solar month (Onam) or by a part of the night the source does not define, and rows that name no part of the day and have no printed date to be checked against. They are listed, each with its reason, in packages/rules/NOT-ENCODED.md.
