A chronological age calculator tells you exactly how old someone is by looking at their birth date and the current date. It figures out how long it’s been since someone was born and shows the answer in years, months, and days. This kind of calculator helps you figure out someone’s age without having to count the time between two dates by hand.
The age calculator compares two important dates: the date of birth and the date of the present. You can use the age calculator for free as many times as you want, and it works for people of all ages. The answer will tell you how old the person is in years, months, and days.
To measure your chronological age, you need to take the current date and subtract your birth date from it. But this is easier because the number of days in each month is different. February has 28 days in a normal year and 29 days in a leap year, for example. You can figure out how old you are in days by doing this:
Days of age = (years × 365) + (months × 31) + days
Chronological age calculator to find out someone’s birthday if you know how old they are and when they were that age. This is useful for family history research when records show a person’s age on a census date, marriage record, or other historical document.
Choose “Date of Birth” from the Calculate menu. Then, type in the person’s age in years, months, or days, and then type in the date when they were that age. To find out when you were born, click “Calculate.” If you only know the person’s age in years (not months or days), the calculator will give you a range of dates when they were born.
For example, the date of birth is March 15, 1990.
Subtract one year from the age of 35 years since March 9 to March 15.
If you know someone’s date of birth and their age at death, this calculator can tell you when they died. This is helpful for genealogy research because it lets you figure out how long an ancestor lived or check the information in documents that list the age at death instead of the actual date.
To calculate, choose “Date of Death” from the dropdown menu, enter the date of birth and age at death, and then click Calculate. The calculator gives you a range of dates when someone died if you only know their age in years (not months or days).
As an example, if someone was born on January 1, 1990, and the calculator uses an average life expectancy of 75 years, it will guess that the person will die on January 1, 2065.
DOB stands for “date of birth” and is made up of years, months, and days.
LE stands for life expectancy in years.
