Five years earlier that the date in question. I leave the simple calculation to the student.
This depends on what today is. See the related link, "100 years ago today". To calculate late the date, subtract 100 from the current year, and use the same date. For example, of today were July 5, 2015, then 100 years ago would be July 5, 1915, since 2015 - 100 = 1915.
Depending on what date you are thinking of, and what date it is today, it would vary a bit, but one could say approximately 3,010 years ago.
The Nintendo 3DS was released about 4 years ago as of today in 2015.
Today's Date - 3.
