What profession did the aunt consult to determine holiday plans?

The aunt consulted an astrologer to determine holiday plans, showcasing her belief in astrology's influence on choosing auspicious dates and times for significant events. In many cultures, astrology is viewed as a guide for personal decisions, and individuals often seek the advice of astrologers to align their plans with celestial events, which are thought to impact one's luck and experiences. This aspect of the story emphasizes cultural beliefs surrounding astrology and how they can play a role in planning life events, such as holidays.
