"Princess Diana's Death to Prince William's Wedding"

John and Doves,
Correct me if I'm wrong but Paris, France is 1 hour ahead of London, England or UTC.
So, if the accident happened at 0.25AM Paris time when the Mercedes hit the 13th pillar in the tunnel on 31st August then it was still the 30th August in London.
I know that the Princess was not pronounced dead till about 3.57AM on the 31st but the killer blow happened at 0.25AM.
That being the case, how interesting is Time and Date's results for 30th Aug 1997 to William's wedding on April 29th, 2011.

From and including: Saturday, 30 August 1997 - Diana's accident time in London (11:25PM)
To, but not including : Thursday, 29 April 2010 - William's wedding

It is 4625 days from the start date to the end date, but not including the end date

Or 12 years, 7 months, 30 days excluding the end date

Alternative time units

4625 days can be converted to one of these units:
Keep looking up,
