Ganesh Puja is preferred during Madhyahna as it is believed that Lord Ganesh was born during Madhyahna Kala. Madhyahna Kala is equivalent to midday according to Hindu division of the day.
As per Hindu time-keeping, the time duration between sunrise to sunset is divided into five equal parts. These five parts are known as Pratahkala, Sangava, Madhyahna, Aparahna and Sayankal. Ganapati Sthapana and Ganapati Puja on Ganesha Chaturthi are done during Madhyahna part of the day and as per Vedic astrology it is considered the most appropriate time for Ganesha Puja.
During midday, Ganesha devotees perform detailed ritualistic Ganesha Puja which is known as Shodashopachara Ganapati Puja.
It is believed that one should not sight the moon on Ganesh Chaturthi. Sighting moon on Ganesh Chaturthi creates Mithya Dosham or Mithya Kalank (कलंक) which means false accusation of stealing something.
As per Puranic legends, Lord Krishna was falsely accused of stealing precious jewel named Syamantaka. After seeing plights of Lord Krishna, Sage Narada informed that Lord Krishna sighted moon on the day of Bhadrapada Shukla Chaturthi and because of that he has been cursed with Mithya Dosha.
Sage Narada further informed Lord Krishna that God Chandra has been cursed by Lord Ganesha that anyone who sighted moon on Shukla Chaturthi during Bhadrapada month would be cursed with Mithya Dosha and would be tainted and dishonoured in the society. On the advice of sage Narada Lord Krishna observed Ganesha Chaturthi fasting to get rid of Mithya Dosha.
Depending on start and end time of Chaturthi Tithi, sighting of moon might be prohibited for two consecutive days. According to DrikPanchang.com rules, Moon should not be sighted while Chaturthi Tithi is prevailing. Further, Moon risen during Chaturthi should not be sighted even if Chaturthi Tithi gets over before moonset.
If anyone has mistakenly sighted moon on Ganesha Chaturthi then he should chant following Mantra to get rid of the curse –
सिंहः प्रसेनमवधीत्सिंहो जाम्बवता हतः।
सुकुमारक मारोदीस्तव ह्येष स्यमन्तकः॥
Simhah Prasenamavadhitsimho Jambavata Hatah।
Sukumaraka Marodistava Hyesha Syamantakah॥
Ganesh Chaturthi is also known as Vinayaka Chaturthi and Ganesh Chauth.
