Number of people are addicted to use the social networking websites especially Face book. Now days, Face book can be used to reveal the sleeping habits of people. It will track the sleeping habits by building up a database when any friend will like the post or will be seen last online busy chatting on Face book. According to the reports, generally people visit Face book in morning hours and last before going to beds. According to Francisco-based software engineer Soren Louv-Jansen, it is possible to get the good impression of their sleeping habits. Louv-Jansen used "time stamps" from Facebook's Messenger service to see when the friends of a particular id were asleep. He created a simple service that checks Facebook every 10 minutes and he got the accurate picture of friends’s face book usage. Louv-Jansen published the source code of program onto GitHub.
