A veteran of 90 Tests and 265 ODIs, Dhoni has been one of the most successful Indian ODI captains. He retired from Test cricket in December last year.
Leading India to two World Cup triumphs in 2007 (T20) and 2011 (50-over showpiece event), Dhoni was once termed as the man with the 'midas touch'. BCCI was early to wish its captain a happy birthday.
"Here's wishing @msdhoni a very happy birthday! Have a #Royal one MS!," tweeted BCCI.
The International Cricket Council (ICC) was also quick to write on its twitter handle. "Happy Birthday to India's most successful captain, @msdhoni!."
