Geoff:
Speaking as an ex-Maths teacher, I would say that your Maths is 
faultless. Using your parameters, the 695 hour figure is 29 days less 
an hour, being pedantic.

However, you have based your calculations on a 52-week year. Bear in  
mind that there is a 7-8 week summer holiday, plus Christmas holidays 
and a break between the Easter and Summer terms. So I suspect that 
the likely discrepancy between Hermione's physical ageing and the 
elapsed real time is probably more like 580-600 hours.
