Abstract: A method and apparatus are provided for managing accounting information of entities having different fiscal calendars. A memory stores accounting data for at least two entities, each of the entities maintaining the accounting data according to a different fiscal calendar. A user interface enables a user to request consolidated accounting information for the entities. Accounting data and/or calendar information of the entities is mapped to a base calendar maintained in the computer system. A processor is provided for accessing the accounting data according to the base calendar instead of the entity calendars to recover, for a specified time period, accounting information responsive to a user request entered via the user interface. The processor consolidates the accounting information for the different entities according to said base calendar.
