Using the calculator
Age Calculator is provided free for general informational and personal use. You are responsible for checking the dates you enter and deciding whether the result suits your needs.
Accuracy and availability
The calculator uses calendar-based date arithmetic, but results may not fit every legal, administrative, or cultural definition of age. The site is provided “as is” and may be changed, interrupted, or unavailable without notice. To the extent permitted by law, no guarantee is made that the service will be error-free or suitable for a particular purpose.
Not medical advice
Results, milestone labels, and any information about baby age are not medical advice, diagnosis, or a developmental assessment. Consult a qualified healthcare professional about health or development questions.
Acceptable use
Do not misuse the website, interfere with its operation, or use it in a way that violates applicable law.
Changes to these terms
These terms may be updated as the site changes. Continued use after an update means you accept the revised terms, where permitted by applicable law.
