About this website
BornCalc is a free collection of 46 age calculators built for real decisions, not just curiosity. Use the Exact Age Calculator to find your age in years, months, and days, compare two birthdays with the Age Difference Calculator, or check school readiness with tools like the Kindergarten Eligibility Calculator. Planning further ahead? The pension age calculators, including the UK State Pension Age Calculator, help you see when you may become eligible, based on your date of birth. Parents can track baby and child age week by week, check a pregnancy due date, and pet owners can convert a dog or cat's age into human years. There is no sign-up and no cost. Every calculation runs in your browser, so the dates you enter are not sent to a server, keeping your information private.
