In this digital world passing time is very easy. There are many possible ways to pass time and it is not necessary that these possible ways are useful ways.
You can get hooked up to your Television set where you have hundreds of channels. Watch movies on Netflix, Amazon Prime, Hot star etc., This is the most common pass time for lazy people in India.
Here I suggest some good ideas to pass time in useful ways and this will not take more than 2-3 hours a day.
Learn some new arts. Dancing, music, painting etc.,
Get into physical activities like swimming, cycling, kickboxing, Zumba etc.,
Work for some social cause like old age homes or orphanages for 2-3 hours a week
Read books, write blogs and reviews
Gather some poor children who cannot afford tuition and teach them
If you don't want to go out of the house, learn yoga and meditation which you can practice at home. You can as well teach them to your neighbors.
