A method for automatically estimating a country where a client computer is configured to operate. The method gathers information of the client computer (e.g., GMT offset, time zone name, daylight savings status, desktop language, etc.) and estimates a country where the client computer is configured to operate using the gathered information and country estimation programming. The method may send information regarding the identity of the estimated country to a server and then receive information from the server based on the estimated country. In other embodiments, the gathered information is sent to the server and the server estimates the country where the client computer is configured to operate. In some embodiments, the country estimation programming comprises a rule engine implemented by rule programming. In some embodiments, the rule engine comprises a recursive rule program.
