Big B further revealed on his blog that having a "chilling time" at home was his decision.
"The boys were having a night out... Abhishek and I... the anniversary behind us he wished we go out to a movie, or dinner... I insisted we chill at home... so we chatted and exchanged notes and saw two movies back to back... cool !
"Yaa... you guessed right... action movies! And when that was over back to our pastime - Football and watching the run up to the World Cup," he wrote on srbachchan.tumblr.com.
Big B, who has worked with wife Jaya in films including "Zanjeer", "Abhimaan", "Chupke Chupke", "Sholay", "Silsila" and "Kabhi Khushi Kabhie Gham", also thanked his family for sharing the blessings on the special day.
"Blessings from elders, from family and the extended family makes the day delightful and comfortable, even though the wife is out of the country... 41 years! It has been a while has it not in the life of an individual," he said.
He also said: "It does not matter whether we are together on the day of the anniversary, what is important is our report card... that should be happy and satisfactory."
"Our report card does not deal with numbers and comment... it merely emphasises the reports of our progeny - Shweta and Abhishek. They are our numbers, standings, rankings, marks... what ever! They be right we all are right," he said.
