Methods and software tools are described for allowing users to navigate through a time schedule quickly and easily. The time schedule interface facilitates a user viewing multiple time periods on an information schedule on a client device quickly without having to completely remake or redraw the entire interface. A user of a computer or similar device is presented with a time schedule interface. This schedule interface may resemble a schedule such as program guide or a train schedule. The schedule typically is composed of a grid or blocks of information defined by two parameters. One parameter is almost always time, while the other parameter depends on the type of schedule. The interface in this invention includes a moveable virtual slider. The slider rests on or is attached to a time scale axis. This time scale axis may be implemented as a horizontal or vertical bar and in addition may contain markings corresponding to time intervals much like a ruler. A user may select and control this slider along the time scale axis. The position of the slider along the time scale axis controls the time periods displayed in the schedule.
