The Law Code of Yājñavalkya 1.10.8

1.10.8

iti paribhāṣitā | hasticchāyeti kecit | seha na gṛhyate kālaprakramāt | grahaṇaṃ somasūryayor uparāgaḥ | yadā ca kartuḥ śrāddhaṃ prati rucir bhavati tadāpi | caśabdād yugādiprabhṛtayaḥ | ete śrāddhakālāḥ | yady api candrasūryagrahe nādyāt iti grahaṇe bhojananiṣedhas, tathāpi bhoktur doṣo dātur abhyudayaḥ || 1.217 || 1.218 ||

Some say it is the shadow of an actual elephant; that is not accepted here because the context is of times. "Eclipse" means the obscuration of the moon and sun. Also whenever there arises a desire for a śrāddha on the part of the performer. By the word "and" (ca) are included the beginnings of the yugas and the like. These are the times for a śrāddha. Even though eating during an eclipse is prohibited by the rule "one must not eat during an eclipse of the moon or sun," nevertheless, the fault falls upon the eater, while there is religious prosperity for the giver. || 1.217 || 1.218
