Aamir took to microblogging website Twitter to share his views.
"Hey guys, 'P.K.' release date is finally locked...This Christmas (Dec 25)...My lucky date! 'Jai Ho'!" Aamir tweeted Monday.
If "Taare Zameen Par", the story of a dyslexic child, which was Aamir's directorial debut, came out on Dec 21 and earned Rs.37 crore, action-thriller "Ghajini" hit the screens Dec 25, 2008. A remake of Tamil film of the same name, it earned Rs.200 crore (approximately $41 million) in less than two weeks.
The movie, which saw Aamir essaying a 22-year-old college student convincingly, grossed Rs.315 crore ($70 million) globally in 19 days since its release.
Aamir's "Dhoom: 3" came out on Dec 20, 2013, and raked in Rs.501.35 crore ($83.56 million) worldwide in 17 days of its release.
Keeping the past record in mind, one can say that X-mas could be lucky for "P.K.", which also features Anushka Sharma.
