Adhik Mass, also known as Purushottam Maas is an extra month in the Hindu calendar that is inserted to keep the lunar and solar aligned. Purushottam is one of the avatars of Vishnu and hence, this holy month is dedicated to Lord Vishnu. In 2018, this extra month started on May 16, 2018, and will end on June 13, 2018. The Amavasya falls on the last of Purushottam Maas i.e., June 13, 2018, Wednesday. Though Amavasya falls every month, the Amavasya Adhik Mass falls once in three years. Hence, it is of great importance.
Adhik Maas is considered inauspicious and no activities like weddings or moving into a new house are conducted. Now, once the extra month ends, special occasions can be conducted from June 14, 2018. The devotees who fasted in the Adhik Maas or those who didn’t must worship Lord Purushottam i.e., Lord Krishna on June 13, 2018, the last day of the extra month.
According to Jyotishacharya Madan Gupta Sapatu, it is important to bath, donate and chant at the end of the month. After opening the fast, the devotees must offer food to the Brahmins. On Amavasya Adhik Maas, one should donate clothes, food items like jaggery, ghee.
In addition to this, offer ‘argya’ to God three times and donate items to the Brahmins or someone who is needy. Furthermore, if women keep fast for Rambha Teej on June 16, 2018, their family will lit up with happiness, peace, and prosperity.
