FAQ
Questions before you trust an age result.
Short answers about precision, target dates, leap years, privacy, official-use limits and the current advertising and analytics status.
How is exact age calculated?
Exact age is calculated by comparing the birth date and target date as calendar dates, then returning full years, remaining months and remaining days.
Can I calculate age on a specific date?
Yes. Use the target date field to calculate age on a past, current or future date after the birth date.
Does it show total days lived?
Yes. The result includes total weeks, days, hours, minutes and seconds, plus milestone dates such as 1,000, 5,000, 10,000 and 20,000 days.
How are leap-day birthdays handled?
February 29 can be selected on valid leap years. In non-leap years, its birthday anniversary is treated as March 1.
Is my birth date uploaded or stored?
No. The calculation runs locally in JavaScript in your browser. No account or backend storage is required.
Can I use this for official or legal age verification?
Use it as a helpful calculation aid, not as official verification. For legal, travel, school or compliance decisions, confirm requirements with the responsible organization.
Are ads or analytics active?
No. The public pages do not load advertising or analytics scripts and do not include reserved ad placements.
