Claim:
A computer-implemented method for use by a database to convert date information using spatial information, the method comprising: storing, by a processing device, in the database date information in a storage format corresponding to a first calendar system; receiving, by the processing device, target spatial information; querying, by the processing device, the database to retrieve a target format indicator matching both the received target spatial information and the date information stored in the storage format, wherein the retrieved target format indicator indicates a target format based on a target calendar system, the target format comprises a calendar system that differs from the first calendar system of the storage format, and includes using the spatial information and the date information as keys to an atlas database table to retrieve the target format indicator, where the atlas database table includes a plurality of atlas entries and each atlas entry includes a calendar format field for storing a format indicator; and converting, by the processing device, the date information from the storage format to the target format.
