Sankashti Chaturthi in June 2027

In Delhi: Tuesday, 22 June, moonrise at 21:52 (a Tuesday, popularly Aṅgārakī).

A vow to Gaṇeśa on the Chaturthī, the fourth tithi, of the dark half of the lunar month, kept on the day the Chaturthī is current at moonrise. The dark half is common practice; the texts read do not state the fortnight. Nirṇaya-sindhu p. 47; Vīramitrodaya p. 38

Each date is worked out for the city’s own moonrise. The Chaturthī begins and ends at the same moment everywhere, but whether it is current at a city’s moonrise depends on the city, so cities far apart can keep different days.

Saṅkaṭahara Caturthī is the South Indian name for the same vow, and the dates here apply to it.

A Saṅkaṣṭī Caturthī that falls on a Tuesday. Śātātapa says a Caturthī on a Tuesday “gives fruit like the equinox”. The name Aṅgārakī is popular; the texts read do not use it. Nirṇaya-sindhu p. 73
