Since the popular Wikipedia website has incorrectly mentioned it as the 19th, the date has spread.
The actor's publicist Dale Bhagwagar said, "I've just written to Wikipedia and all the other sites and papers who have picked it up from there and carried the incorrect date, requesting them to make the change.
But I guess it's too late for this year. Randeep's phone hasn't stopped ringing with people wishing him a day in advance".
Luckily for the actor, his close friends know the correct date, so he wont miss the fun on the 20th.
