Krishna Chaturthi prevailing at local moonrise; if on no day, the Udaya-tithi day.
Ganesha/Narada Purana: the Ganesha vrat and the Moon arghya on the Krishna Chaturthi bring the end of troubles, freedom from debt, removal of obstacles, the blessing of children; Ganesha cursed the Moon with a blemish and then ordained the arghya to that very Moon on Sankashti — without seeing the Moon the Sankashti is incomplete (the reverse on Vinayaka Chaturthi — seeing the Moon is forbidden).
Angarki Sankashti: Mangala (Angaraka) did penance to Ganesha and won the boon that the Tuesday Sankashti be named after him and its fruit equal a whole year's Sankashtis — hence lakhs at the temples of Maharashtra-Karnataka on Angarki (Siddhivinayak, Ashtavinayak, Dagdusheth). The Sankashti date is moonrise-vyapini — the day on which the Chaturthi is present at moonrise; Vinayaka's is midday-vyapini.
12 in UK (London). Lunar months do not align with the calendar year, so the count can be 11 or 13.
2 of the 12 dates differ from India for London, because the tithi is judged at the local moment (sunrise/moonrise/Pradosh) and UK is hours away from India in time.
Sankashti = the Krishna Paksha Chaturthi (after the Purnima) — the fast from sunrise to moonrise, paran after the arghya to the Moon, the removal of troubles; Vinayaka = the Shukla Paksha Chaturthi (after the Amavasya) — puja at noon, do not see the Moon (the tale of the blemish); the Vinayaka of Bhadrapada is Ganesh Chaturthi, the Sankashti of Magha is Sakat Chauth; both in the list above.
The Sankashti that falls on a Tuesday — Ganesha's boon to Angaraka (Mars) after his penance that the Tuesday Sankashti's fruit equal a whole year's Sankashtis; 1-3 times a year; lakhs fast and queue at temples in Maharashtra; special for those with Mangal dosha; you will find '(Angarki)' marked in the list above.
After the moonrise time (above) give the arghya in the Moon's direction (east) or take the reflection in a mirror/water in the thali — the paran is valid; the vrat complete; do not delay too late into the night; if moonrise is very late (after 10), the unwell and pregnant take fruit earlier.
