The budget planning calendar is the schedule of activities for the development and
adoption of the budget. It should include a list of dates indicating when specific
information is to be provided by each information source to others. A budget calendar
should be prepared for the timing of each aspect or operation of the budget. A timetable
must be given to operating managers to submit their proposed budgets so the overall
company budget may be prepared on time. The schedule of due dates for documents
and reports must be adhered to. Review and approval dates should also be specified.
The schedule dates should be realistic and attainable.
