A generation ago, the fiscal year in the United States was changed. It was advanced forward three months, from July 1 to October 1, the rationale being that this would give the United States Congress three additional months to complete its work on the budget.
What we've learned since then is that the U.S. Congress has a great capacity to wait to the last minute and beyond. The three months did not buy any additional time. Instead, it brought additional delay.
