The Mumbai Indians batsman, who happens to here for his team's clash against Kolkata Knight Riders, will begin the day with a customary cake-cutting ceremony at the team hotel.
Earlier, the Cricket Association of Bengal celebrated Tendulkar's birthday a day in advance by cutting a 10-pound cake in the presence of 100 blind students.

The blind students from Narendrapur Ramakrishna Mission Blind School and Light House for the Blind cut the cake in the evening.
"We are overwhelmed with joy. We want Tendulkar to live 100 years," a message from the CAB read.
Wednesday's 40-pound cake cutting ceremony will be a private affair near the dressing room. Tendulkar's wife Anjali joined him last night along with team owner Nita Ambani for more celebrations. (Read more: Kolkata fans plan a lavish birthday party for Tendulkar)
The greatest compliment Sachin received was probably when Sir Don Bradman said Sachin reminded him of his own younger self. Getty Images.
The chocolate cake will be made up from special cocoa from Ghana and Madagascar. It will have an image of Tendulkar and it could be that of the World Cup-winning moment of April 2, 2011.
In a career spanning 24 years, Tendulkar has got almost all the batting record to his name other than Brian Lara's Test highest of 400 not out.
Tendulkar, who has called it quits from the ODI format to prolong his Test career, has a colossal 18426 runs from 463 matches with 49 hundreds at an average of 44.83. (Read more: Factfile of Sachin Tendulkar)
In the leading run-getters list of Test matches, Tendulkar is sitting on 15837 runs with 51 hundreds, way ahead of South African veteran Jacques Kallis who with 13128 runs is the only playing batsman to be in the race at fourth place.
"Let me take this opportunity to thank all the people in India and well wishers all over the world who have supported me and showered me with unconditional love," said the veteran, whose wife Anjali was by his side during the ceremony.
"It has been really special and it is because of their good wishes that I am standing here," he added.
Tendulkar said he wanted to thank each one of his fans personally for supporting him for over 24 years.

"Since I can't do that, it is a good opportunity to thank the every little thing that they have done for me, like fasting for me during injuries. I just wanted to say thank you," he said.
Tendulkar got the first bite of his birthday cake from Anjali's hands who giggled after being called from the backstage by the batsman on the insistence of the present journalists and photographers.
"Now, don't ask her to put it on my face next," joked the veteran cricketer.
