One of my ancestors was said to have died 11th March 1844, as written on her headstone, but her death cert says she died 12th March. The headstone writing clearly says 11th.
To a scientist that is almost within experimental error ....
. Perhaps the person died late on the day but the death was recorded after midnight - or something like that ?
Or to add a bit of humour, it took her a few seconds to die, starting 11:59:58 on the 11th, and they were dead by 3 seconds past midnight on the 12th.

Imagine being born at the very strike of midnight on the dot.
