A fast and flexible random date generator
Whether you are a developer building a test database, a writer creating character profiles, or an auditor selecting days for compliance checks, you often need to generate random dates quickly. This random date generator allows you to pick any number of random days between a specific start and end point.
Because the tool runs entirely in your browser, it is incredibly fast and completely private. Your selected date ranges and generated lists are never uploaded to a server or stored anywhere. You can safely use it for internal company projects or sensitive mock data generation without worrying about data leaks.
Tailor your results with smart filters
Generating a raw list of dates isn't always enough. Depending on your use case, you might need specific constraints. This random date picker includes several built-in filters to refine your output:
Exclude weekends: By checking the "Weekdays only" option, the generator automatically removes all Saturdays and Sundays from the available pool of dates. This is perfect for simulating business transactions, stock market activity, or school attendance records.
Prevent duplicates: When you need a distinct set of days, the "Unique dates" toggle ensures that no single date is picked more than once. The algorithm uses a Fisher-Yates shuffle on the available days to guarantee mathematically unique selections.
Chronological sorting: Raw random data can be hard to read. The "Sort chronologically" option takes your randomly selected dates and orders them from earliest to latest before displaying them, saving you the trouble of sorting them manually in a spreadsheet.
Common ways to use a random date picker
Software testing and mock data. Developers and QA testers frequently need to populate databases with realistic information. Instead of manually typing out dates or writing custom scripts, you can generate hundreds of dates instantly. If you also need numerical data, you can pair this with our Random Number Generator.
Random birthday generator. Novelists, game developers, and tabletop RPG players often need to flesh out character backstories. By setting the date range to a specific decade (e.g., 1980 to 1990), you can instantly generate realistic birthdays for an entire cast of characters. It is also useful for testing age-verification gates on websites.
Audits and spot checks. Quality assurance teams and financial auditors often rely on random sampling to review records. A random day generator provides an unbiased way to select specific days of the year to pull logs, review camera footage, or check inventory.
Giveaways and lotteries. If you are running a promotion where a winner is chosen based on a specific day they entered, you can use this tool to fairly and randomly select the winning date.
Formatting your output
Different regions and software systems require dates to be formatted in specific ways. To save you time, this tool can output your list in four distinct formats:
- ISO (YYYY-MM-DD): The international standard format. This is the best choice for developers, databases, and software testing because it is unambiguous and sorts alphabetically in the exact same order as it does chronologically.
- US (MM/DD/YYYY): The standard format used in the United States, placing the month before the day.
- EU (DD.MM.YYYY): The standard format used across most of Europe and many other parts of the world, placing the day before the month.
- Long Format: A highly readable, localized text format (e.g., "Friday, October 6, 2026") based on your browser's current language settings.
Once you generate your dates, simply click the copy button to paste the list directly into Excel, Google Sheets, or your code editor. If you need to analyze the dates further, such as finding out exactly how much time sits between two of your generated dates, you can use our Date Difference Calculator, or determine what day of the week a specific date fell on with the Day of the Week Calculator.
