A recent suggest a correction I received.......

Suggested Edit:

"From and including: Thursday, March 18, 1847
To, but not including Friday, April 12, 1872

Result: 9157 days
It is 9157 days from the start date to the end date, but not including the end date

Or 25 years, 25 days excluding the end date"

***just one problem.............the stone says aged 21 years and 25 days.

I'm not a fan of calculated dates, even when the calculation is based on the correct information, and most likely will not add them.
