ज्योतिःशास्त्रम्
स्वात्यन्तरे यन्त्रनिष्ठे शक्रस्योत्थापयेद्ध्वजम् ।हर्यृक्षपादे चाश्विन्यां सप्ताहान्ते विसर्जयेत् ॥ ६५ ॥
In the full Agni Purana this is chapter 121, verse 65.
At the end of Svati, once the pole stands in its frame, raise Indra's flag. In a quarter of Shravana and in Ashvini, take it down after a week. (Our text is unclear here: the timing words of the first line.)
Simple meaning: Indra's flag is raised at a set time and taken down after a week.
सर्वं हेमसमं दानं सर्वे ब्रह्मसमा द्विजाः ।
On the day of a solar eclipse, every gift, Brahmin and water is held to be very holy.
ध्वाङ्क्षी महोदरी घोरा मन्दा मन्दाकिनी तिला ।
The Sun's entry into a sign has seven names by the day of the week.
बालवे कौलवे नागे तैतिले करणे यदि ।
When the Sun enters a sign during these four karanas, people are happy.
