टिप्पणी: सभी समय १२-घण्टा प्रारूप में सान दिएगो, संयुक्त राज्य अमेरिका के स्थानीय समय और डी.एस.टी समायोजित (यदि मान्य है) के साथ दर्शाये गए हैं।
आधी रात के बाद के समय जो आगामि दिन के समय को दर्शाते हैं, आगामि दिन से प्रत्यय कर दर्शाये गए हैं। पञ्चाङ्ग में दिन सूर्योदय से शुरू होता है और पूर्व दिन सूर्योदय के साथ ही समाप्त हो जाता है।
Kali Chaudas is also known as Bhut Chaturdashi. Kali Chaudas is mainly observed in Western states especially in Gujarat.
Kali Chaudas is observed during Chaturdashi Tithi during Diwali festivity. However Kali Chaudas day should not be mixed with Roop Chaudas and Narak Chaturdashi as it might fall one day before of Narak Chaturdashi. The day of Kali Chaudas is decided when Chaturdashi prevails during midnight which as per Panchang is known as Maha Nishita time.
As rituals of Kali Chaudas involve visiting crematorium during midnight for offering Puja to the Goddess of darkness and to Veer Vetal, the day of Kali Chaudas is decided when Chaturdashi prevails during midnight.
It seems that most Panchang do not make such distinction and list Kali Chaudas with Roop Chaudas and Narak Chaturdashi. Hence one has to be cautious while looking for Kali Chaudas date.
Further Kali Chaudas should not be confused with Bengal Kali Puja which is observed one day after Kali Chaudas when Amavasya Tithi prevails during midnight.
