Amavasya

Amavasya (Amavasya) — the thirtieth tithi of the lunar month, the new-moon tithi. It closes the dark half of the month — the krishna paksha. At this moment the angle between the Moon and the Sun goes to zero, and the two luminaries stand in conjunction — the Moon's disk is not visible in the sky. This is the darkest day of the month, and tradition reads it as a day of deep memory, honoring ancestors, and release from karmic bonds.

Place in the system

Tithi is the lunar day, 12° of divergence between the Moon and the Sun. Amavasya runs fifteenth in the dark half — krishna paksha, the last before Shukla Pratipada, which will open the new bright half. The angle between the luminaries goes to zero, and Amavasya becomes the point of transition. In the amanta reckoning used here, Amavasya also closes the lunar month itself: the next tithi opens a new month. In the North Indian purnimanta reckoning the month ends with Purnima, and the month names for the dark half shift forward by one.

Classical lists place the fifteenth tithi of both pakshas in Purna; in this corpus Amavasya is set apart from the class and treated separately — its character differs too much from Purnima's.

Amavasya's deity is Pitri, the souls of ancestors; some lists also connect it with Yama. Amavasya is the day of their direct presence and request: the ancestors wait to be remembered.

Practical meaning

By the classical rules of muhurta, Amavasya is favorable for offerings to ancestors — shraddha and tarpana. Tradition directly calls it unsuitable for important worldly undertakings, but the most suitable day for rites of memory, offerings to those in need on ancestors' behalf, fasting, and meditation.

In Indian folk practice, Amavasya is one of the most important days of the year for honoring ancestors. Several Amavasyas of the year carry their own name and festival weight: Bhadrapada Amavasya (Ashvin in the purnimanta reckoning) — Sarva-Pitru (Mahalaya), the main day of ancestor remembrance; Pausha Amavasya (Magha in the purnimanta reckoning) — Mauni, a day of silence and bathing in holy waters; Ashvin Amavasya (Kartika in the purnimanta reckoning) — Diwali, the night of Lakshmi.

Amavasya is also a time when, by tradition, spirits descend to earth, and so on this night it is customary not to sleep, not to leave the house without need, and to recite mantras. This is not fear but care: the dark night asks for stillness.

In daily practice

Amavasya is a day for offerings to ancestors. It is good in the morning to perform tarpana — an offering of water with sesame and rice, mentally addressing departed ancestors on both the maternal and paternal lines. This takes a few minutes and requires no special ritual setting.

Amavasya also suits charity on ancestors' behalf — giving to the poor, supporting a teacher, leaving an offering at a temple. Tradition holds such charity to be pacifying for the ancestors.

Amavasya does not suit important worldly undertakings — a wedding, a move, opening a new venture, an important deal. The dark tithi asks for stillness.

The day is also good for meditation, for the practice of letting go, for quiet inner work. The darkest day of the month is a space ready to hold inner light.

How much this day is yours is refined by Tara Bala — the count from your birth nakshatra to the one the day falls under. Amavasya sets the background of memory, and the personal layer shows how much this memory currently matches your own rhythm.
