Random Birthday Generator Free | Fake DOBs for Testing

Random Birthday Generator

Generate realistic-looking random birthdays and dates of birth for software testing, QA, development, mockups, fictional profiles, sample datasets, and classroom exercises.

Choose an age range, specific date range, or completely random mode, then generate one or hundreds of fictional DOBs in seconds.

The basic workflow is:

Choose Range → Generate Birthdays → Copy or Download

Generated dates are random test data and are not linked to real individuals.

How to Generate a Random Birthday

Creating a random date of birth is simple:

Choose Age Range, Date Range, or Completely Random.
Enter your preferred age or date limits.
Select the date format.
Choose how many birthdays to generate.
Click Generate Birthdays.
Copy individual results or copy the full list.
Download the results as TXT or CSV if needed.

You can also keep the default settings and generate test birthdays immediately.

Free Random Date of Birth Generator

Developers and testers often need realistic DOB values without using a real person's personal information.

This random date of birth generator creates fictional birthday data that can be used for:

Registration forms
Development databases
QA test cases
CRM demos
User-profile mockups
App prototypes
CSV datasets
Spreadsheet practice
Fictional characters
Classroom exercises

No registration is required.

Random Birthday Generator by Age Range

Age Range mode is useful when your test data needs to represent people within specific ages.

For example:

Minimum age: 18 Maximum age: 35

The generator creates dates of birth that produce an age between 18 and 35 based on the current date.

This is more accurate than simply subtracting a birth year from the current year because it accounts for whether the person's birthday has already occurred this year.

Accurate Age-Based DOB Generation

A person's age depends on the full date, not only the birth year.

For example, two people born in the same year can still have different ages today depending on their month and day of birth.

This tool calculates age using:

Birth year
Birth month
Birth day
Today's date

That makes it useful for testing:

Minimum-age requirements
Age-restricted interfaces
Registration validation
User eligibility rules
Profile forms

Generate Birthdays Between Two Dates

Choose Date Range when you need random birthdays within exact calendar limits.

For example:

January 1, 1990 → December 31, 2005

The generator selects random valid dates between those boundaries.

This is useful for:

Historical datasets
Controlled test records
Age-validation scenarios
Spreadsheet exercises
Database seed data

Future dates are prevented from being treated as birthdays.

Completely Random Birthday Generator

If you do not need a specific range, choose Completely Random.

The tool generates a random fictional birthday from a sensible predefined historical range through today.

This is useful when you simply need believable sample DOBs quickly.

Generate Multiple Random Birthdays

Need more than one date?

Choose the number of results you want and generate a complete batch at once.

Bulk generation is useful for:

Development databases
QA datasets
CRM demos
Spreadsheet imports
User mockups
Testing scripts
Sample CSV files

You can generate large lists without manually creating each birthday.

Generate Unique Dates of Birth

Enable Unique Dates Only when every generated birthday should be different.

This can be useful when creating fictional user records where duplicate dates would make the dataset less varied.

If duplicates are acceptable for your test case, you can disable the option.

Choose a Date Format

Different applications and countries use different date formats.

The generator supports common formats including:

MM/DD/YYYY

Example:

07/24/2001

Common in US-style interfaces.

DD/MM/YYYY

Example:

24/07/2001

Common in many international systems.

YYYY-MM-DD

Example:

2001-07-24

Useful for:

Databases
APIs
CSV files
Development environments
ISO-style date fields

Month DD, YYYY

Example:

July 24, 2001

Useful for human-readable profiles and mockups.

DD Month YYYY

Example:

24 July 2001

Another readable international format.

Show Calculated Age

Enable Show Calculated Age to display the current age beside each generated birthday.

Example:

March 18, 1998 — Age 28

This is useful when testing interfaces that display both DOB and age.

Include Weekday of Birth

You can optionally show the weekday for each generated date.

Example:

1998-03-18 — Wednesday

This can be useful for:

Classroom exercises
Date calculations
Data-analysis practice
Fictional profiles

Include Zodiac Sign

The tool can optionally display the common Western zodiac sign associated with the generated birthday.

For example:

1998-03-18 — Pisces

This is mainly useful for fictional profiles, games, or sample data where zodiac information is required.

Sort Birthdays Oldest to Newest

Bulk results can be sorted by date.

Available sorting options include:

Random order
Oldest to newest
Newest to oldest

Sorting is useful when reviewing large datasets or preparing spreadsheet imports.

Copy Individual Birthdays

Each result includes a Copy button.

This makes it easy to move one DOB into:

Signup forms
Test accounts
CRM records
Development tools
Spreadsheets
Mockups

Copy All Birthdays

Use Copy All to copy the entire generated list.

Each result appears on its own line for easy pasting into:

Google Sheets
Excel
Text editors
Database tools
QA documentation
Test scripts

Download Random Birthdays as TXT

Download a plain-text list when you need simple one-date-per-line output.

TXT files are useful for:

Development scripts
Quick datasets
Notes
QA documentation

Download Random Birthdays as CSV

For structured data, download the results as CSV.

CSV output can include fields such as:

Date of birth
Formatted DOB
Age
Weekday
Zodiac
Data status

This makes the tool especially useful for developers, analysts, and QA teams.

Random DOB Generator for Form Testing

Date-of-birth fields can involve more validation than simple text inputs.

Use random DOBs to test:

Required fields
Date pickers
Minimum-age limits
Maximum-age limits
Date formatting
Error messages
Validation logic
Database storage
Mobile layouts

Random Birthday Generator for QA Testing

QA testers can generate DOBs for positive and boundary test cases.

For example, you may want to test:

Exactly 18 years old
Younger than 18
Exactly 65
Leap-day birthdays
Different date formats
Large batches of fictional records

This makes the generator useful for repeatable testing workflows.

Fake DOB Generator for Development

Using real personal data in development environments can create unnecessary privacy risks.

A fake DOB generator provides fictional dates that can be used when building:

User systems
Account profiles
Checkout flows
Membership applications
CRM interfaces
Mobile apps
Admin dashboards

Generated DOBs are sample data, not verified identities.

Random Birthdays for Databases

Developers often need realistic records when creating or testing database schemas.

A fictional user record might contain:

Fake name
Fake phone number
Fake email
Random birthday
Fictional address

Using generated values helps keep development data separate from real customer information.

Random Birthdays for CSV Test Data

CSV files are commonly used for imports and migrations.

Random DOBs can help you test:

Bulk imports
Column mapping
Date normalization
CRM uploads
Spreadsheet formulas
Data validation
Export workflows

Choosing ISO-style YYYY-MM-DD output is especially useful for technical datasets.

Random Birthday Generator for Fictional Characters

Writers and designers can also use the tool to assign birthdays to fictional characters.

You can generate:

A random birthday
Current age
Weekday of birth
Zodiac sign

This can help with:

Character profiles
Game characters
Fiction projects
Role-playing scenarios

Random Birthday Generator for Students

Students can use random dates for:

Statistics exercises
Spreadsheet practice
Date calculations
Programming assignments
Database projects

Because the dates are fictional, there is no need to use real personal information.

Random Birthday vs Random Date Generator

A random date generator may create any date, including future dates.

A random birthday generator is specifically designed for dates of birth.

Feature	Birthday Generator	General Random Date Generator

Privacy-Friendly Test Data

Generated birthdays are not pulled from real user profiles.

They are created randomly according to your selected settings.

This makes them suitable for:

Development
QA
Demos
Mockups
Fictional profiles
Classroom work
Sample datasets

You should still avoid combining fictional data with real personal information in ways that could create confusion.
