About This Site
Free, accurate age calculators and plain-English guides for parents, teachers, therapists and anyone who needs an exact age.
By Sandeep · Updated November 2026
What We Do
This site started with one tool: a chronological age calculator for people who need an exact age in years, months and days, often for a test, a report or a form. It has grown into a set of free calculators and guides covering testing, babies and children, development and the different ways age can be measured.
Our goal is simple. Every tool should give the right answer, show how it got there, and explain what the result means in plain English.
Who It Is For
- Speech-language pathologists, psychologists and occupational therapists who need a fast, reliable chronological age for scoring.
- Teachers and school staff checking school entry ages and test ages.
- Parents tracking a baby’s age in weeks or months, or a premature baby’s corrected age.
- Students learning about chronological, mental and developmental age.
- Anyone who wants to know exactly how old they are.
Who Runs the Site
The site is created and run by Sandeep, a researcher and writer who builds free health and education calculators. Sandeep is not a doctor or licensed clinician, so every calculator follows a published method, and every guide is based on reputable sources such as test manuals, medical guidelines and peer-reviewed research.
How We Keep Things Accurate
We explain every formula on our methodology page and follow the standards in our editorial policy. Pages are reviewed regularly and updated when guidelines change.
Independence
We are not affiliated with, or endorsed by, Pearson, Super Duper Publications, Curriculum Associates (Brigance) or any other test publisher. Product names are used only to describe compatibility. The site may show advertising to stay free, but advertisers never influence our content.
