There are three types of appropriations bills: regular appropriations bills, continuing resolutions, and supplemental appropriations bills. Regular appropriations bills are the twelve standard bills that cover the funding for the federal government for one fiscal year and that are supposed to be enacted into law by October 1. If Congress has not enacted the regular appropriations bills by the time, it can pass a continuing resolution, which continues the pre-existing appropriations at the same levels as the previous fiscal year (or with minor modifications) for a set amount of time. The third type of appropriations bills are supplemental appropriations bills, which add additional funding above and beyond what was originally appropriated at the beginning of the fiscal year. Supplemental appropriations bills can be used for things like disaster relief.
