Frequently Asked Questions
How accurate is this age calculator?
This age calculator provides highly accurate results down to the second. It takes into account leap years, different month lengths, and time zones. If you include your birth time, the calculation will be even more precise.
Why does my age in months seem different from what I expected?
Age in months can sometimes be confusing because months have different lengths (28-31 days). Our calculator uses a precise algorithm that counts the exact number of months and remaining days between your birth date and the current date.
Do I need to enter my birth time?
No, entering your birth time is optional. If you don't enter it, the calculator will assume midnight (00:00) as your birth time. Adding your birth time will make the hours, minutes, and seconds calculations more accurate.
How is the next birthday countdown calculated?
The next birthday countdown calculates the exact number of days, hours, minutes, and seconds until your next birthday based on the current date and time. It automatically determines whether your birthday has already occurred this year or is coming up.
Can I use this calculator for someone else's age?
Absolutely! You can calculate anyone's age by entering their birth date and time. This can be useful for parents tracking their children's age, genealogy research, or any other purpose where you need to know someone's precise age.
How can I share my age results?
Click the "Share Your Results" button below your age results. This will generate a link that you can copy and share via email, social media, or messaging apps. The link will contain your age information so others can see your results.
Does this calculator work for dates in the future?
This calculator is designed to calculate age based on past dates. If you enter a future date, you'll receive an error message as it's not possible to have a negative age.
