It seems that as time has moved on, the use of fireworks has changed.
When I was a child, it was 'Guy Fawkes' night, children made an effigy of the anarchist Guy Fawkes and stood on street corners and asked passers by for 'A penny for the Guy'. The theory was that the money given was used to buy fireworks (it often went on sweets instead!) and the fireworks would be set off on 5 November, when a bonfire was lit, and everyone had sparkers, ate sausages, and so on.
Now, it seems to be 'Firework Night' - less bonfires, more and more expensive and elaborate fireworks with evenings setting them off being any date from the beginning of October through to New Year - another major firework nights since Millennium Eve.
I do believe that fireworks should only ever be seen at licensed displays operated by trained people, and that over-the-counter sales should be banned for safety and peaceful evenings reasons.
