गते वर्षद्वये सार्द्धे पंचपक्षे दिनद्वये । दिवसस्याऽष्टमे भागे पतत्येकोऽधिमासकः
gate varṣadvaye sārddhe paṃcapakṣe dinadvaye | divasasyā'ṣṭame bhāge patatyeko'dhimāsakaḥ
جب دو برس اور آدھا گزر جائے، اور اس کے ساتھ پانچ پکش اور دو دن بھی ہو جائیں، تب دن کے آٹھویں حصے میں ایک اَدھِماس (اضافی مہینہ) واقع ہوتا ہے۔
Brahmā (deduced; Vaiṣṇavakhaṇḍa discourse style)
Scene: A learned jyotiṣin explains the occurrence of adhimāsa using a pañcāṅga and celestial diagrams; the moon’s phases and a time-wheel are depicted to show the intercalary adjustment.
Ritual observances depend on precise sacred time (kāla), and Purāṇas preserve calendrical rules for correct practice.
The calendrical rule is taught within the Ayodhyā Māhātmya context, supporting vrata practice at/connected to Ayodhyā.
It gives a rule for when an adhimāsa (intercalary month) occurs—relevant for timing long lunar vows.
