What does your culture celebrate with fireworks?

On a yearly basis, not counting special events like the Olympics, we (the denizens of the USA) put up the biggest fireworks display for our Independence Day (July 4th) from that evil Empire of Britannia, who now in one of those ironies of history is our closest ally, and vice-versa. I even get "Happy 4th of July" well-wishes from British friends of mine! Strange how the worm turns.

The other only real consistent time you see/hear fireworks is on New Year's Even at midnight, but it's a less planned out and watched thing - it just sorta happens spontaneously by those who've consumed too much liquor and have access to explosives, or by carefully orchestrated TV events, like the big Times Square deal.

Fireworks feature prominently in professional sports, too, as well as in Las Vegas, but as this is private entertainment and nothing to do with any national celebrations, I'm not going to count this category of pyrotechnic extravagances.

So, readers from outside the US, during what events do your countries generally employ the patriotic use of fireworks to celebrate?
