Since Elvis Presley was born on January 8, 1935, and died on August 16, 1977.
Means that Elvis Presley died when he was 42 years, 7 months, 8 days excluding the end date.
Hope this helped! c:
Assuming you are talking about the American singer Elvis Presley, he was 42 years old at his time of death. His period of living is 1935 to 1977.
