Very Limited Coverage
The furthest this app will go back is January 1st 1970. Cannot enter in or scroll back further. I was born during the 1950s. This app cannot be used to determine retirement information for Social Security.
One year later there is no update to resolve earliest possible Birth Year. Change to typing in Birth Year or make into multi-segment scroll where there is a wheel for each digit (e.g. 1.9.5.7). In this manner you can determine time for any date in A.D.
