Apparatuses and methods to operate a commute time function of a communications device are described herein. In one embodiment, the commute time function is automatically activated based on an event and is then performed by (i) determining an up-to-date commute time based on commute information and (ii) displaying or speaking the up-to-date commute time on the device. In one embodiment, triggered by and before the occurrence of a calendar event, a device obtains a current commute time (based on the commute information and based on current traffic conditions). In this embodiment, the device reschedules the calendar event based on the current commute time, by sending an update to the contacts with whom the user is to meet that indicates a change to the calendar event. Other embodiments are also described.
