A calendar bar utility with a special user interface may be integrated and displayed simultaneously with an electronic mail list inbox. The calendar bar user interface comprises a linear display arranged into multiple, chronologically-arranged, time periods. Upon selection of a specific time period, such as a day, or the current day, subdivisions of the time period, e.g. hours of a day, are displayed in a similar format. The calendar bar also allows multiple calendars, for example the personal calendar of the user, and a team calendar for multiple individuals, to be displayed simultaneously for easy access. Selection of a specific time period causes data associated with any event in that time period to be displayed next to the designated time period, or, alternatively, in a separate window. The data associated with the event may vary in detail and scope depending on the designer preferences, but will typically include the start and end times, the location, topic, type, i.e. call-in, video conference, etc., the participants, relevant telephone numbers, network addresses, electronic mail content and/or threads or summaries thereof and references to any relevant data and materials.
