About this helper
This calculator compares a birth date with an as-of date and counts full calendar years, months, and days. It also shows total days and the next birthday. It is useful for everyday reference and planning, not for legal age verification.
Does my birth date leave my device?
No. The age calculation runs in your browser and the site does not receive the dates you type.
Can I calculate age on another date?
Yes. Change the Age on date to calculate age at a past or future date.
Is this legal age verification?
No. Use official documents and local rules when legal age matters.
