Free Online Random Date Generator
Instantly generate random dates, times, weekdays, or months without leaving your browser. Start by choosing a date range and format, then hit Generate to see your results appear in the panel. The tool features five distinct modes for different needs, including date ranges, standalone times, combined timestamps, weekdays, and months. Each mode offers a tailored settings panel, ensuring you only deal with options relevant to your current task. For power users, uploading a CSV or JSON file automatically sets your range and count, making it easy to export fresh data for your spreadsheets or test environments.
Random Date
Pick random calendar dates between any start and end date with six format options including ISO 8601 and Unix timestamps.
Random Time
Generate random times in 24-hour or 12-hour AM/PM format with optional seconds precision.
Date & Time
Combine random dates and times into full timestamps for test data generation and scheduling simulations.
Random Weekday
Pick random days of the week with filters to include only weekdays, weekends, or any custom combination.
Random Month
Select random months from a configurable list, useful for quizzes, scheduling, and data simulations.
Online Random Date Generator with File Upload and Export
Creating a randomized dataset takes only seconds. Once you specify your date bounds and output format, the generator populates a clean grid with your new values. Every entry includes an index number for quick reference during data validation. When your list is ready, you can copy everything to your clipboard or save it as a text file. Customize the output further by choosing a separator like a comma, semicolon, or tab to match the requirements of your destination application.
Upload CSV or JSON Configuration Files
Speed up your workflow by dragging and dropping a CSV or JSON file directly onto the settings panel. If you use a CSV, ensure it has columns for your start date, end date, and count; JSON files should follow a similar object structure. This automation is particularly helpful for recurring projects where you need to generate fresh data using the same parameters.
Six Date Formats and Four Time Formats
Choose from six versatile date formats, ranging from standard ISO 8601 and Unix timestamps to user-friendly month names. The time settings are just as flexible, offering 12-hour and 24-hour options with optional seconds precision. In combined mode, you have the freedom to pair any date style with any time format to create the exact timestamp your project requires.
Weekday and Month Randomizers with Custom Filters
This randomizer goes beyond standard calendars with specialized modes for weekdays and months. Use the weekday grid to filter your results to specific days, such as excluding weekends for business-only data or focusing on specific days for a rotating schedule. The month picker works similarly, allowing you to limit the output to certain seasons or academic terms by simply toggling months on or off.
Sort and Deduplicate Results
Refine your output by sorting results chronologically or alphabetically with a single toggle. If you are working with a narrow date range, enable the unique dates option to avoid repeat entries. These quality controls work across all generation modes, ensuring your data is ready for immediate use once you copy or export it.
Free Random Date Generator for Developers, Testers, and Students
This tool streamlines tasks for everyone from developers needing quick test timestamps to QA specialists performing boundary tests on web forms. Students can generate datasets for statistics assignments without tedious manual entry, while educators can quickly pull random dates for classroom exercises. Privacy is a priority, so all processing happens right in your browser. Since no data ever touches a server, your results are completely private and disappear the moment you close the tab.
No Signup, No Watermark, No Limits
Access every feature, format, and export tool instantly without any barriers. You can generate hundreds of values per batch as often as needed, with no limits on usage. Every text file you download is clean and free of watermarks, keeping the focus entirely on your data. Your information never leaves your machine throughout the entire process.
Client-Side Processing for Complete Privacy
Your browser handles all the heavy lifting using local JavaScript for generation and formatting. Because the tool makes no network requests during the process, your configuration settings and results stay strictly confidential. This local-first design makes it a safe choice for handling sensitive project timelines or proprietary scheduling data.
