There is no such thing as 'premonition' as in a spiritual sense. People constantly think of things more often than they can recall but they only become significant when the 'premonition' actually refers to something solid.
But it does happen does it not. As said all sorts of thoughts are flashing through and when something turns up that matches up you thunk........ But having said that the built in calendar aspect must have a relevance - after all EDF sent a similar E-mail earlier this year so presumably some form of clock was ticking.
