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 (GMT+1).
The tithi is judged at the local moment (sunrise, moonrise or sunset) and Dublin is hours away from India in time, so the same tithi can fall on a different calendar date here.
