I don't believe in fate, luck (except as random chance influenced by outside factors), or any other superstition. Numerology, in particular, makes me chuckle; the belief that certain days could be more or less unlucky just because their callendar numbers include multiples of the number 7 is rediculous.

After all, callendars are nothing more than an artificial construct desined by humanity and changed multiple times over the last 2 millenia as our methods of tracking the passage of time became more exact, so 7/7/2007 could appear on many different callendars on different days of different years. Are they all luckier and we just don't know it because we don't use certain ancient callendars any more?

Was 7/7/0007 a lucky day even though the current callendar hadn't been invented yet and wouldn't be for over 1,000 more years?

If I make up my own callendar and include lots of 7s in it, will they all be lucky days?
