To ensure appropriate amounts of time/days are spent on various activities/projects, it would be helpful to be able to monitor that information. That way, if someone skips something or can't get to it for a while, they can spot it and make sure to put time into it over the next few days/week/planning time period. For example, getting to the gym, reading a book and other personal activities as well as job related activities - like making sales calls that are done on an irregular basis.
