Ever wondered exactly how many days are between two dates?

I built a simple Date Difference Calculator as part of DataFormatTools that calculates the difference between any two dates instantly.

What it calculates
📅 Years
🗓️ Months
📆 Weeks
🔢 Days
⏱️ Total days between dates

It’s useful for calculating:

Project durations
Age differences
Subscription periods
Deadlines
Work or study periods
Time between important dates
⚡ Simple & Fast

Just select your start date and end date, and get the result instantly.

No signup. No complicated setup.

Generate Strong Passwords Instantly with a Free Password Generator 🔐

Strong passwords shouldn't be difficult to create.

I built a simple Password Generator as part of DataFormatTools that lets you generate strong passwords directly in your browser.

You can customize:

🔢 Password length
🔠 Uppercase letters
🔡 Lowercase letters
0️⃣ Numbers
🔣 Special characters
⚡ Multiple password suggestions
📋 One-click copy
🔒 Privacy First

The generator runs 100% in your browser.

Your generated passwords aren't uploaded to a server or logged.

Why I built it

I wanted a quick developer-friendly tool that I could open whenever I needed a strong password without installing software or dealing with unnecessary steps.

I'm also building DataFormatTools into a larger collection of 100+ useful developer tools for working with JSON, YAML, XML, CSV, security utilities, and more.
