With this tool you can discover how much time of the day you spend on Twitter. The calculation is based on tweet activity and the estimates may be too low for people who spend a lot of time reading tweets, but do not write many tweets.

Basically the algorithm assumes that for any tweet from an account, the account is also engaged in other Twiter activities, within a certain time interval. For this time interval it is assumed that the account was active on Twitter for 100% of that time. Of course it is possible that an account was multitasking during that time, and also did other things. It is also assumed that everyone sleeps for 7 hours during every 24 hour period.

The score gives the percentage of time an account was active with Twitter while awake.
