August marks the end of Aadi and the beginning of Avani, which is a month deeply rooted in the worship of Lord Vishnu and Lord Krishna.

Devotees also celebrate Krishna Janmashtami (the birth of Lord Krishna), which falls during Avani. Temples host special kirtans, bhajans, and midnight prayers to mark Krishna's birth, and families observe fasting and recite Krishna's stories.
