In Hinduism
Jyotisha (astronomy and astrology)
Source: Wisdom Library: Brihat Samhita by VarahamihiraRātra (रात्र) refers to the “night”, according to the Bṛhatsaṃhitā (chapter 8), an encyclopedic Sanskrit work written by Varāhamihira mainly focusing on the science of ancient Indian astronomy astronomy (Jyotiṣa).—Accordingly, “If the disc of Jupiter should appear of the colour of fire, there will be fear from fire; if yellow, there will be disease in the land; if dark-blue, there will be wars; if green, suffering from thieves, and if of blood color, suffering from weapons. If the disc of Jupiter should appear of the colour of smoke, there will be drought; if it should be visible during day, rulers will perish and if it should appear large and clear at night [i.e., rātra], mankind will be happy”.

Jyotisha (ज्योतिष, jyotiṣa or jyotish) refers to ‘astronomy’ or “Vedic astrology” and represents the fifth of the six Vedangas (additional sciences to be studied along with the Vedas). Jyotisha concerns itself with the study and prediction of the movements of celestial bodies, in order to calculate the auspicious time for rituals and ceremonies.
Shaivism (Shaiva philosophy)
Source: Brill: Śaivism and the Tantric TraditionsRātra (रात्र) refers to the “night”, according to the Guhyasūtra chapter 3.—Accordingly, “[...] [If] one wanders in the cremation-ground at night (rātra), with a skull in one’s hand and a Khaṭvāṅga, covered in ashes, that is called the cremation-ground observance. If one dances, sings, laughs and talks madly, with the body smeared in ashes and wearing rags, this is called the Gaṇavrata. One performs the Clod-of-Earth Observance by being engaged in recitation, feeding on alms, sleeping on the earth, with senses controlled, engaged in meditation and restraint. [...]”.

Shaiva (शैव, śaiva) or Shaivism (śaivism) represents a tradition of Hinduism worshiping Shiva as the supreme being. Closely related to Shaktism, Shaiva literature includes a range of scriptures, including Tantras, while the root of this tradition may be traced back to the ancient Vedas.
In Buddhism

Source: academia.edu: A Study and Translation of the GaganagañjaparipṛcchāRātra (रात्र) refers to the “night”, according to the Gaganagañjaparipṛcchā: the eighth chapter of the Mahāsaṃnipāta (a collection of Mahāyāna Buddhist Sūtras).—Accordingly, as Gaganagañja said to Ratnapāṇi: “Son of good family, those sixty-four dharmas are included in one hundred twenty-eight dharmas. What are those one hundred twenty-four? [...] (59) the lightness of body is included in knowing the proper time for eating and making an effort at practicing vigilance in the beginning (pūrva-rātra) and end of the night (apara-rātra); (60) lightness of thought is included in eagerness and examination; (61) being free from lassitude is included in impermanence and suffering; (62) desire is included in the absence of what belongs to the ego and property; [...]’”.
