🪷 सुब्रह्मण्य षष्ठी · Subrahmaṇya Ṣaṣṭhī

Tradition

Tradition: Shaiva

Vrata: Yes (fasting day)

How the day is decided

The Śukla Ṣaṣṭhī at sunrise (the tithi at sunrise is whole for the day's rites); when it holds at two sunrises, the second day (the tithi's chapter); touching no sunrise, the day it runs.

Source: Dharmasindhu, tithi-nirṇaya (OCR 1158-1166 yugma, 1351-1790 by tithi). Computed on the Sūrya Siddhānta's sunrise, tithi and Moon at Ujjayinī (a city's page uses that city's sunrise).
