Is There a Two-Day Error?

This is part of the death certificate of Minerva (Sargent) Strobel who died in Evanston, Cook County, Illinois, on 6 March 1943.

The death certificate lists her as being 94 years, 9 months, and 18 days old--with a date of birth of 18 May 1848.

When her birth date and death date are entered into Wolfram Alpha, a two-day discrepancy seems to be apparent between the age on the death certificate and the age per Wolfram Alpha.

I'm about 95% certain I know why the discrepancy exists. I'm curious if readers do.

The Master Genealogists also calculates 94 years, 9 months, 16 days.

The answer is very simple-
The first day of life would have ended on May 19, 1848 and her last full day of living ended March 5th 1943. The actual day of birth and day of death are not used when calculating life spans.
