Krishna Chaturdashi prevailing at local Nishita (Hindu midnight) — the puja window is computed for this city's night.
Shiva/Skanda Purana: the night of the Krishna Chaturdashi is dear to Shiva — on this night the pillar of fire (Lingodbhava) appeared which Brahma and Vishnu could not measure; the vigil and abhishek of this night remove a year's sins; keeping the Masik Shivratri vrat for 12/14 consecutive years brings marriage, children and liberation (folk belief); the Chaturdashi is Nishita-vyapini — the night at whose middle the Chaturdashi is present is the vrat day (the list above follows this rule — sometimes it begins on the evening of Trayodashi).
The puja of the four prahars: the first prahar (evening — abhishek with milk), the second (night — curd), the third (midnight — ghee), the fourth (dawn — honey/sugar); 'Om Namah Shivaya', bel leaves and aarti in every prahar; householders should worship at least once in the Nishita Kaal (midnight ± 24 minutes — above).
Tuesday, January 5, 2027 — Pausha Masik Shivratri (CDT).
The tithi is judged at the local moment (sunrise, moonrise or sunset) and Chicago is hours away from India in time, so the same tithi can fall on a different calendar date here.
