Last Modified Date
Timestamp showing when the FPDS transaction record was last updated in the source system. It reflects the most recent modification to the transaction data, not the date of award action or obligation.

Use Cases
- Dictionary lookup and field explanation
- SQL filtering and grouping
- Analytical reporting and reusable query building
Common Usage
- Incremental refresh and change-data capture
- Audit and data quality reconciliation
- Sorting or deduplicating records by most recent update
Common Mistakes
- Using it as the date of contract award or modification action
- Comparing it as plain text without converting to a datetime type
Query Guidance
Use in WHERE clauses to isolate records updated after a cutoff, and in window functions or ORDER BY clauses to keep the latest version of a transaction. Example pattern: WHERE lastModifiedDate >= '2023-10-25' and ORDER BY lastModifiedDate DESC. Parse the string into a timestamp before date arithmetic or time-based comparisons.
