DOB Age Calculator: Calculate Age in Days, Months and Years from Date of Birth
How does the Online DOB Date of Birth Calculator Work?
The online DOB date of birth calculator takes the day, month and year of birth and then uses the date technology that is in-built in your internet browser to check for correct birthday dates. It then calculates your current exact age as per the Gregorian calendar. This is the calendar that is used in most of the world today, having been introduced by Pope Gregory XIII in October 1582 to reform and replace the Julian calendar.
This online date of birth (DOB) calculator answers your question of what is my age today by calculating how many years, months, days, hours, minutes and seconds have passed since the day you were born up to the second you press the Calculate My Age button.
For your convenience, the DOB calculator attempts to automatically get your current locale from the regional settings on your computer. This is important in order to adjust the age calculation because of the fact that our planet is divided into more than 24 time zones.
Note that we do not store your age and location data on our website. Moreover, any data you enter on the online DOB calculator is never shared with anyone, and is lost once you leave the website.
