Two friends Abhishek and Deepak meet after a long time and had a discussion as given below:
Abhishek: We met after a long time that is after 20 years. How are you?
Deepak: I am good, Abhishek. Now I am a married man having four children.
Abhishek: That’s great. How old are they?
Deepak: Product of their ages is 144 and the sum of their ages is equal to today's date.
Abhishek: Ok. But, I still don't get it.
Deepak: Oh and by the way, the oldest son of mine is as old as the sum of the rest.
Abhishek: FYI, I got it.
Guess the date of the particular month and year.
