The budget cycle consists of different phases: preparation and formulation, approbation by a vote, execution, revision, and control of the budget. The budget refers to a fiscal year, and, sometimes, the budget covers a period larger than the fiscal year (multi-year budget). The budget cycle often begins the previously fiscal year (preparation and approbation phases) and finishes the next fiscal year (control phase). At the origin, the budget cycle symbolized the separation between the executive and the legislative powers: the Parliament by its vote approve the budget and control the execution of the budget made by the Government. Even if the budget still has this role, nowadays, it becomes a real tool for the Government in their forecasts and a tool of management.
