Its Imran Khan's Birthday.

Born on 13th(4) January 1983 which makes him a Number 4 (Rahu) person in numerology.

He is a Capricorn (ruler Saturn – Number 8) and his destiny number also adds up to Number 8, which means he is ruled by one of the most powerful planets Saturn twice.

He will always have to struggle his way to reach the top and prove himself with every film of his.That’s the shani effect.Also his name adds up to Number 26(8) which will add to his woes.
Imran will now enter his 30th year and it isn’t looking that promising if compared to last year.
Luckily, his next release Ek Main Aur Ekk Tu (the double ‘K’ is numerologically corrected) is now adding up on a positive number and hence would do well at the box office. 
But Vishal Bhardwaj’s Matru Ki Bijlee Ka Mandola will flop at the box office.
Wearing a Blue Sapphire (after testing) on his middle finger on a Saturday might just help him achieve super stardom just like his mamu Aamir Khan.
