Guide / FAQ
Here's how to get the most out of Baby Calculators.
Q. Is my baby's birth date stored on a server?+
A. No. Every calculation on this site happens entirely in your browser, and the date you enter is never sent to or stored on a server. See our Privacy Policy page for details.
Q. How is the number of months calculated?+
A. We calculate the total number of months and remaining days based on the calendar difference (year, month, day) between the birth date and today, shown for example as "8 months 14 days."
Q. How is the age (in years) calculated?+
A. It's calculated the standard international way: your age increases by one on each birthday, based on whether this year's birthday has already passed.
Q. Can I use this on mobile?+
A. Yes. The site is optimized for mobile screens, so it's easy to use on your phone.
Q. What other calculators are coming?+
A. We plan to add more practical parenting calculators over time, such as a pregnancy week calculator and a government benefits calculator.
