If you are asking yourself "How old am I?" and want to get the answer by hand, you would need to make sure you account for leap years (365 instead of 364 days, February gets an extra day), so it can be tedios task. If you are doing this calculation for a historical figure, then you would need to take into account possible differences in the calendar used when they were born and nowadays. For example, some Eastern European countries used the Julian calendar unitl they switched to the Gregorian one in late 19-th and early 20-th century (in different years for the different countries).
If you need to know your age by the hour, minute or second, you can use our time duration calculator instead.
How old am I?
While looking deceptively simple, the answer to the above question is not nearly as straightforward as you think. But you might say that even 2-3 year-olds can use their fingers to answer that question, so how hard could it be, right? Answering "How old am I?" is actually pretty complex - read on to learn why.
This age calculator is based on the way human age is calculated in most Western countries. This means that when a person is born their age is 0 and it becomes 1 exactly an year from their birth, or as we say, on their birthday. The same goes for property, establishments, etc.
In other cultures, such as in East Asian, age reckoning is different. In some countries, a person begins their life at the age of 1 (by Western standard). Then another year is added to their age at New Year’s Day, even if this happens to be the second day of their life. This has largely to do with traditional fortune-telling methods and religion; and it could create a difference in a person’s age of one or two years between Western and Eastern counting systems.
To add to the confusion, when asked about their age some people present their complete age, while other present their running age. So for example, if at your last birthday you have completed your 21st year you might say that you are 21-years-old. However, you could also say you are 22-years-old, which would be your running age (as in the age you are currently towards completing).
It is not so obvious how to answer the "how old are you" question now, is it? Even our age calculator will only give you one of the possible answers...
