宗四分比丘隨門要略行儀 1.35

1.35

作六念法　第一念。知月朔大小（若月大白月十五日已前。應云此月大白月。一日乃至十五日。隨日稱之。若從十六日已後皆云黑月。應云此月大黑月。一日乃至十五日隨之。若月小應云此月小。作法准前。若依祇律。白月恒大。黑月隨大小稱之。今既欲知此方道俗兩種日月不同祇律。依彼西土作法。但可以義長通稱月大小。復標沙門日月白黑之別）。

Method of practicing the six recollections: The first recollection: Knowing whether the new moon's month is full or short (If the month is full, before the fifteenth day of the śuklapakṣa, one should say: "This month is full, the śuklapakṣa, the first day," up to "the fifteenth day," stating it according to the day. From the sixteenth day onward, all are called the kṛṣṇapakṣa; one should say: "This month is full, the kṛṣṇapakṣa, the first day," up to "the fifteenth day," stating it accordingly. If the month is short, one should say: "This month is short," performing the procedure as before. If following the Mahāsāṃghika-vinaya, the śuklapakṣa is always full, while the kṛṣṇapakṣa is stated according to whether it is full or short. Now, since we wish to know the differences between the monastic and secular calendars of this land, which differ from the Mahāsāṃghika-vinaya, in performing the procedure according to that western land, one can generally designate the month as full or short based on the extended meaning, while additionally indicating the distinction between the śukla and kṛṣṇa fortnights of the śramaṇas.)
