What should we do — and avoid — in Puruṣottama (Adhika) Māsa?
avoid new beginnings like weddings, gṛha-praveśa and mundan; fill the month with japa, scripture, dāna and Viṣṇu worship.
Because the extra month has no saṅkrānti of its own, it was once called mala-māsa, an “impure” month unfit for ceremonies. Tradition says Viṣṇu took it under his protection and gave it his own name, Puruṣottama, so it became a month for devotion rather than worldly beginnings.
Usually avoided: weddings, engagement, sacred thread, mundan, gṛha-praveśa, starting a new business, buying major property, and first-time kāmya vratas. Routine life, medical treatment and already-running work continue normally, and regular śrāddha and tithi observances are still done.
Commonly done: reading the Bhāgavata or Gītā, the Puruṣottama Māsa kathā, Viṣṇu Sahasranāma, lighting a lamp daily, an early bath, one-meal days, and dāna. A well-known custom is giving 33 malpuās or other sweets in dāna, often in a bell-metal bowl, a number usually linked to the 33 devas.
