With some people tweeting hundreds of times a day, you sometimes wonder if they ever go to sleep. Now there is a tool that can help you confirm this. SleepingTime is a simple tool that tells you when any Twitter user probably sleeps. All you have to do is enter the username of that person.

The tool works by analyzing the last few (or few hundred) tweets of that person, combined with the timezone information provided in their profile and estimates when the person probably goes to sleep and for how long. It is of course not 100% accurate but gets pretty close if you are an active Twitter user. The tool also gives you sleeping times for some tech superstars and some media personalities from India.

Features:

• See when your Twitter friends sleep.
• Dead simple tool, just enter the Twitter handle.
• Doesn’t work for private/locked accounts.
• No registration required.
