Hi, I'm Thijs Lintermans
Web Developer & Creator of WhatTheCalculator
I'm a web developer from Belgium passionate about building creative, useful websites that make people's lives a little more interesting. You might also know me online as LinthDigital.
WhatTheCalculator started as a personal project to combine my love for web development with my curiosity about the little things in life. I wanted to create tools that answer questions people actually wonder about—from "how many days have I been alive?" to "how much am I really spending on subscriptions?"
Every calculator on this site is carefully built to be accurate, easy to use, and genuinely helpful. I research the formulas, verify the calculations, and constantly improve based on user feedback.

About WhatTheCalculator
What We Do
WhatTheCalculator is a collection of fun, educational, and quirky calculators designed to help you explore everyday questions you never thought to ask. From practical tools like sleep debt and water intake calculators to playful ones like your age on other planets, there's something here for everyone.
Why We Built This
The idea is simple: take the mundane, make it interesting, and add a dash of curiosity. These calculators aren't just about numbers—they're about discovering patterns in your daily life, learning something new, and maybe having a laugh along the way.
Our Commitment to Accuracy
Every calculator is built with accuracy in mind. We research the formulas, account for edge cases (like leap years in age calculations), and provide clear explanations of our methodology. When we cite statistics, we base them on published research and studies.
Always Improving
This project is constantly evolving. New calculators are added regularly, existing ones are improved based on feedback, and the site is optimized for speed and usability. Have an idea for a calculator? Let me know!
