Śrāvaṇa Somavāra

Why it appears

The local weekday and the selected lunar month meet.

Open Pañcāṅga checks the local vāra and the regular lunar month at sunrise. The observance appears when the vāra is Somavāra and the month is Śrāvaṇa under one of the disclosed month systems.

The two systems begin Śrāvaṇa at different points in the Moon’s cycle. In a pūrṇimānta calendar, Śrāvaṇa begins just after Pūrṇimā. In an amānta calendar, it begins just after the following Amāvāsyā, about two weeks later. So an early Monday can already be in Śrāvaṇa in the pūrṇimānta calendar while the amānta calendar still calls it Āṣāḍha. Open Pañcāṅga checks both documented rules and tells you which one matched.

Akashvani describes Monday fasting during Śrāvaṇa and identifies the observance as Śrāvaṇa Somavāra. A separate Akashvani report documents contemporary first-Monday worship at Śiva temples across Uttarakhand. These sources establish documented practice; Open Pañcāṅga’s astronomy and selected calendar system determine the local civil date.

This identification depends on the selected calendar system; it is not a statement that every Hindu household follows one universal Śrāvaṇa Monday practice.
