muddassir1718/Age-Calculator — reverse-engineered prompt

Build me a simple, polished age calculator web app that lets someone enter a birth date or choose two dates and instantly see the time between them in a fun way.

It should show the result in years, months, weeks, days, hours, and minutes, plus extra estimates like heartbeats, Earth trips around the sun, sleep time, and breaths taken. Make it feel friendly and easy to use, with a nice responsive design that works well on mobile and desktop. Include clear labels, validation for bad or future dates, and a reset option.

Use the existing project setup and make sure it runs locally with npm install and npm run dev. If the app setup needs an API key, keep the env example clear, but don’t make the age calculation depend on AI unless it’s already required. Look up current docs online if you need to.
