The astrologer thought that he had killed a man after a quarrel. Hence he had run away from his village, changed his appearance and his persona when he arrived in the city, and become an astrologer. However, he still felt guilty for what he had done. When he came to know that the man he thought he had killed was actually alive, the dark load inside him disappeared, and it made his day, i.e. he felt relieved and happy. This is the significance of the title ‘An Astrologer’s Day’.
