Software test data
Generate ISO, SQL or Unix values for date fields, calendars, sample databases and QA edge cases without uploading a dataset.
Random Date Generator
Pick one or many dates from any valid range with weekday filters, unique results, optional times and copy-ready formats.

DIRECT ANSWER
How does a random date generator work?
The tool converts the start and end into an inclusive count of calendar days, asks the browser’s cryptographic random source for offsets in that range, applies your weekday and uniqueness rules, then formats the selected dates.
- 1
Set the range
Choose the first and last allowed date. Both endpoints can be selected.
- 2
Apply the rules
Choose quantity, weekdays, unique dates, sorting, time and an output format.
- 3
Generate and use
Create a new sample, then copy individual dates, copy the list or download CSV.
PRACTICAL USES
One random date picker, several practical workflows
The useful difference is not decoration—it is control over the valid sample space and the output you can actually paste into another tool.
Random birthday generator
Use the birthday preset for an adult-age window or set an exact year range for fictional profiles and form testing.
Planning and fair date draws
Pick a day for a classroom prompt, content review, team rotation or voluntary activity, with weekends included or excluded.
Writing and research prompts
Draw historical or future dates for timelines, journal exercises and scenario ideas, then keep the weekday visible.
COPY-READY FORMATS
Choose a date format that will not be misread
Numeric day and month order can be ambiguous. ISO 8601 puts the year first; regional formats remain available when a spreadsheet or form expects them.
| Format | Example | Useful for |
|---|---|---|
| ISO 8601 | 2026-07-30 | APIs, databases, international exchange |
| US | 07/30/2026 | Forms expecting month/day/year |
| UK / EU | 30/07/2026 | Forms expecting day/month/year |
| Long date | July 30, 2026 | Human-readable prompts and documents |
| ISO date-time / SQL / Unix | 2026-07-30T14:20:00Z | Development, logs and test data |
KNOW THE LIMITS
Know what the random result does—and does not—prove
It is a software draw. The browser provides a cryptographically strong random source, but this page is not a certified lottery, legal assignment or auditable selection service.
Filters change the sample space. If only weekdays are active, weekends have no chance of being selected. Unique mode also limits how many results fit a short range.
Times are generated in UTC. Date-time, SQL and Unix outputs use the same UTC timestamp so copied formats stay consistent across devices.

COMMON QUESTIONS
Random date generator: frequently asked questions
Answers about date ranges, multiple dates, weekends, unique results, birthdays, times, formats, randomness, spreadsheets and privacy.
How do I generate a random date between two dates?
Set the Start date and End date, choose how many results you need, and select Generate dates. The range is inclusive, so either endpoint can appear.
Can I generate multiple random dates at once?
Yes. Enter a quantity from 1 to 100. Turn on Unique dates when you do not want the same calendar day repeated, provided the filtered range contains enough days.
How do I generate random dates excluding weekends?
Turn on Weekdays only, or use the seven weekday buttons to choose an exact set. The generator will draw only from active weekdays.
Can this generate a random date and time?
Yes. Turn on Include random time. The tool selects a second within each chosen UTC calendar day and offers ISO date-time, SQL and Unix timestamp formats.
Can I use it as a random birthday generator?
Yes. The Random birthday preset creates an adult-age window from 65 years ago through 18 years ago. Change either date when your fictional profile or test case needs a different age range.
Are the random dates unique?
They are unique only when Unique dates is on. In that mode the same calendar day cannot appear twice, even when random time is included.
What date formats are available?
ISO YYYY-MM-DD, US MM/DD/YYYY, UK/EU DD/MM/YYYY, a long written date, ISO date-time, SQL date-time and Unix timestamp are included.
Are the results truly random?
They are generated with the browser’s cryptographic random source and uniform offset selection. That is strong software randomness, but it is not a claim of physical randomness or certified lottery operation.
Can I paste the dates into Excel or Google Sheets?
Yes. ISO and regional date formats copy as plain text, and Download CSV includes the formatted value, weekday and ISO timestamp. Check the spreadsheet locale if it automatically swaps day and month.
Are my date ranges or results uploaded?
No. Generation, filtering, formatting and CSV creation run in your browser. The tool does not send the selected range or generated dates to a server.
