Sins of omission and commission, when not intentional, can be atoned by certain expiatory rites known as prāyaścitta. Abhijit is one of such rites. It is actually a minor Vedic sacrifice similar in structure to the major sacrifice Soma, but requiring just a day to perform. It is specially recommended as an expiation for the sin of killing a brāhmaṇa.
Abhijit is also the name of a nakṣatra (star or asterism) counted as the 28th, after uttarāṣāḍha. In mythological works, Abhijit is described as a daughter of Dakṣa-Brahmā and as a wife of Candra (the moon).
The auspicious period that occurs at midnight is also called abhijit. Lord Kṛṣṇa is said to have been born at that time.
