Frequently asked questions
Quick answers to help you get accurate results.
Is age calculated from the full birth date or just the year?
It uses the full month, day, and year, so the age increases only when the corresponding birthday is reached.
Can I calculate age on a past date?
Yes. Change the Age as of field to calculate age on any date after the birth date.
Is the birth date saved?
No. The birth date is processed only in your browser and is never sent to or stored on DailyCoreNews servers.
