Eight more calculators families use alongside this, all free, no account needed.
Your age is the time elapsed from your date of birth to today (or any date you choose). The calculator counts the completed years, then the leftover months and days (accounting for different month lengths and leap years) so you get your exact chronological age, not just whole years.
Enter your date of birth and the calculator shows your age broken down into years, months, days, and even hours and minutes. It also gives your total age expressed purely in months or days, which is handy for forms, babies' milestones, and official paperwork.
Chronological age is simply how long you have been alive, measured from your date of birth, the everyday meaning of age. It differs from 'biological age', which estimates how old your body seems based on health markers.
The calculator shows a countdown to your next birthday along with the weekday it falls on. Enter your date of birth to see how many days, and your upcoming birthday's day of the week.
Yes. Set the reference date to any day instead of today, and the calculator works out the age or time difference between your date of birth and that date, useful for eligibility cut-offs, school admission dates, and official deadlines.
For babies born premature, paediatricians often use 'corrected age' (the chronological age minus the number of weeks the baby was born early) to judge development milestones until about age two. This calculator gives chronological age; ask your paediatrician about corrected age for a preterm baby.
