Computing an approximate DoB is then a task of time subtraction, the outcome of which would be as precise as the accuracy with which the age of the person is known. In genealogy, one may sometimes be interested in determining the date of birth (DoB) of a deceased person for which the known information is only the date on which death occurred, as well as their approximate age in years, or sometimes years and months.

How to determine the DoB of a deceased person? Citing a chronological age with completed years, months, and days is the most accurate answer one can give. However, sometimes one would say their running age, which is the current age plus one, which may make the answer ambiguous. Sometimes a person would cite their complete age as in the example above, and that is straightforward enough. Consequently the second birthday is when a person becomes two years of age, and so on. The age consequently becomes 1 year, 0 months, and 0 days exactly a year from their birth. According to it a person who was just born has an age of 0 years, 0 months, and 0 days. This birthday age calculator is based on the way human age is calculated in most Western countries. The answer to this question may be somewhat complicated if an exact solution is sought. Obviously, you need to know their date of birth, or at least the month and day of the month (if unsure of the year of birth, enter any year prior to the current year). The tool can be used to find the time you have to plan a birthday party for a friend or relative as well. If you are asking yourself how long until your next birthday party, then the birthday calculator is an easy way to find out without doing any time difference math yourself. This software can also be used to determine the date of your next birthday as well as how many days until it comes. If you want to see how old you will be at any given point in the future, or how old were you at a specific date in the past, simply enter that date in the second input field before pressing the calculation button.
