The chaste wife, after passing one year doing this worship, should fast on the full-moon day in the month of Kārttika [October-November]. Carame ahani means the full moon. [Note: Since the vow starts after the dark moon of the following month (Mārgaśira), during the waxing phase of the moon, and the vow ends on the full moon of Kārttika month, the vow does not last a full year, but would be two weeks short. Only in the case of adding an extra Puruṣottama month would there be over a full year’s vow. ]
