The appropriate age for Mundan, or the first haircut in Hindu tradition, typically ranges between the first and third years of a child's life. This ritual is often conducted when the child is one, three, or five years old, as these odd years are considered auspicious. The specific timing can vary based on regional customs, family traditions, and astrological considerations. Some families consult with priests to select the most favorable date and age for the ceremony. Ultimately, the appropriate age for Mundan is influenced by cultural beliefs and individual family preferences, ensuring the ritual is conducted at a time deemed most beneficial for the child.
