When exactly is my birthday?

The exact age is not simply given in years. It is only exact in seconds. The age calculator therefore calculates the exact time in hours, minutes and seconds from birth to the present day.

Of course, you also get the number of years, months, weeks and days as a result, but anyone can work that out for themselves.
