Various embodiments of the invention provide methods, systems, and computer-program products for determining whether a local time for a first party is within a calling window of time for originating a communication by a second party to a mobile device of the first party. For particular embodiments, information about the mobile device is retrieved by a computer-program application residing on the device. Depending on the embodiment, this information may comprise contact preferences, a current time of a location where the mobile device is located, a geo-location of the device, and/or a time zone for the location where the device is located. In various embodiments, once the information has been retrieved, at least a portion of the information is sent to the second party to be used to determine whether the local time for the first party is within the calling window for originating the communication to the mobile device.
