1Endings pile up on the same day
An end date is not necessarily the day the equipment is finished. Of the 208 Defense Department contracts this site holds as of 2026-09-06, 34 end on 30 September. A year has 365 days, yet one contract in six closes on this one. This series works through eight records to test that skew.
2What 30 September is
The U.S. federal fiscal year begins on 1 October and ends on 30 September of the following year. Appropriations are enacted, spent and closed on that boundary. Aligning the end of a contract with the end of a fiscal year puts budget management and contract management on the same calendar.
3The skew is not limited to one day
Tabulating end dates, the four most common are all quarter-ends.
| End date | Contracts | Share of the 208 |
|---|---|---|
| 30 September | 34 | 16.3% |
| 31 December | 26 | 12.5% |
| 31 March | 15 | 7.2% |
| 30 June | 10 | 4.8% |
Together those four account for 85 contracts, or 40.9%. Widen the test to any last day of a month and the count reaches 139, or 66.8%. Two contracts in three are written to end just before the month turns.
4Named by the calendar year, closed by the fiscal year
The description runs to five words, and the first of them is CY. That abbreviation stands for calendar year, a different way of counting from the fiscal year marked FY. This is the only record among the 208 that uses CY, while 25 records use FY. A single contract thus carries work named on one calendar and an ending cut on another.
The next article looks at a contract signed in September 2024 that calls itself FY25.
Why it matters
End dates are frequently placed to suit the budget calendar rather than the completion of work. When comparing contract length, the interval between start and end is a better measure than the end date itself.
