Frequently Asked Questions

How is age calculated exactly?

Age is calculated by finding the difference between your birth date and the target date. The calculator accounts for leap years and varying month lengths to give you precise results in years, months, and days. It then converts this to other units like weeks, days, and hours.

Can I calculate my age on a future date?

Yes! You can use the "Calculate Age On" field to enter any future date and see what your age will be on that date. This is useful for planning milestones or seeing how old you'll be on a specific future date.

Why does the calculator show different units?

Different contexts require different time measurements. For example, parents often track babies' ages in months or weeks, while some applications need age in total days or hours. The calculator provides all these units for maximum flexibility.

How accurate is the next birthday countdown?

The next birthday countdown is calculated from today's date to your upcoming birthday. It automatically determines whether your birthday has passed this year and calculates the days remaining until your next birthday with complete accuracy.

Can I use this for someone else's age?

Absolutely! You can enter any birth date to calculate anyone's age. This is useful for calculating the age of family members, friends, or historical figures. The calculator works for any date from 1900 to 2100.

What if I was born on February 29 (leap day)?

The calculator handles leap day births correctly. It accurately calculates your age accounting for leap years. Your next birthday countdown will show either February 28 or 29 depending on whether the upcoming year is a leap year.

How do I calculate age at a historical date?

Simply enter the birth date in the first field and then change the "Calculate Age On" field to the historical date you're interested in. This is useful for determining someone's age at a specific point in history or for genealogical research.

Is my birth date information stored anywhere?

No. All calculations are performed entirely in your browser. Your birth date and other information are never sent to any server or stored anywhere. The calculator is completely private and secure.
