Vrat / Satyanarayan puja on the day Purnima prevails at local midday; Snan-Daan on the Udaya-tithi day.
The Moon is at full strength on Purnima — its influence on the mind (Moon) is intense, hence the vrat's restraint and the Moon arghya; the most auspicious day for Vishnu puja and the Satyanarayan katha (Skanda Purana, Reva Khanda) — the katha may be held on any day but Purnima and the Sankranti are best; the fruit of the Purnima bath (Ganga-Yamuna-Narmada) and charity is multiplied.
The vrat rule: the Purnima by the udaya tithi or moonrise-vyapini — the fast on the udaya tithi day, the Satyanarayan katha and Moon arghya on the evening when the Purnima is present at moonrise (usually the same day; sometimes a day earlier — the list above follows the udaya rule, choose the katha evening from the tithi window); paran after seeing the Moon or the next morning.
Friday, January 22, 2027 — Pausha Purnima Vrat (AEDT).
The tithi is judged at the local moment (sunrise, moonrise or sunset) and Sydney is hours away from India in time, so the same tithi can fall on a different calendar date here.
