The 67-year-old star, who is the host of Bigg Boss, has written in his blog that he will be celebrating his father's birthday on November 28 instead of 27, which is a Friday, as he will be shooting that day.

"There is the matter of my Father's birth anniversary being celebrated on the 28th November. His birthday is on the 27th, but I record Bigg Boss on a Friday so that would be not possible, hence the next day," Amitabh wrote.

The entire Bachchan family, including the family of Amitabh's brother Ajitabh, are preparing for a special celebration.

"Preparations for that are afoot. I shall be reciting and singing my Father's works and hopefully the family shall be putting in their bit - Abhishek, Shweta and Aishwarya along with Ajitabh’s children," he added.

This year will be the late poet's 101 birth anniversary and the star is anticipating a grand commemoration.

"It shall be 101 years since his birth and it is apt to think of a commemoration. It will probably be at the Bhartiya Vidya Bhavan since it is this institution that has organized the event," he wrote.
