Generate random dates between any two dates — useful for testing, data generation and sampling.
Also generate timestamps with the Unix Timestamp Generator or create test data with Lorem Ipsum JSON.

A random date generator is an essential tool for developers, QA engineers, data analysts, and database administrators who need realistic-looking test data quickly. This tool works as a test date generator, sample data creator, and mock date generator for any project that requires date-based dummy data.
Software developers use random date generators when building and testing applications that process date inputs — such as booking systems, event calendars, age verification systems, and analytics dashboards. Populating a test database with realistic random dates distributed across a meaningful range is far more effective than using the same fixed date repeatedly, as it helps surface edge cases related to date arithmetic, month boundaries, leap years, and timezone handling.
Data analysts and researchers use random date sampling when creating representative synthetic datasets for mockups, presentations, or privacy-safe demonstrations of data pipelines. The multiple format options in this tool — ISO, US, UK, and long format — mean the output can be pasted directly into the format required by the target system without any reformatting. ISO format is the standard for databases and APIs; US and UK formats are common in spreadsheets and reports depending on the region. The chronological sort option produces a clean ordered list that is immediately usable as a timeline or log sequence without additional processing.
When used alongside other test data generators — such as random name generators or JSON placeholder tools — random date output helps build complete, realistic mock datasets that can expose date-handling bugs that would never appear with fixed or sequential dates. Testers often generate a batch of 50 to 100 random dates spanning several years to ensure that date-parsing code handles all months, including February edge cases, and correctly orders records across year boundaries.
