I'm bound to say: The same as Germany!
Now it's August and the time is ripe for the first Christmas chocolates and gingerbread filling the aisles of the supermarkets!
I have no doubt, in one week I can buy all the Christmas sweets. (or could I buy them by now?) At last! Half a year of waiting has its end! The last chocolate Easter bunny had been eaten by my fiancé last week. I need new sweets. I want Christmas sweets now in summer!

But something is new. I recognized that last year for the first time but I am quite sure that was not the first year: A week or two before Halloween all the Christmas stuff was disappeared. Only a handful of broken chocolate Father Christmas and smashed dominoes (gingerbread with filling in form of a cube, called in Germany "Dominosteine") had been left in a dark corner of the supermarket. I was full of panic! I didn't buy any Christmas sweets for family and friends yet. I thought there might be time enough to buy later. It was October and there was nothing left!!!
The shelves suddenly were filled with little pumpkins, costumes and artificial maple-leaves and everything was colored in black and orange. Halloween products as far as the eye could reach and special Halloween offers for Halloween bakery and cooking. I think, it was all the stuff, that any German marketing departments thought it must be typical for Halloween. I have to point that out: Germans only knew Halloween from TV. Halloween never was a traditional holiday in Germany. But now children love it and they want to be customized, trick-or-treating and Halloween parties.
Much to my relief a couple of days after Halloween Christmas had its return to the supermarket. Father Christmas and the other Christmas sweets were back, ready to be bought and eaten. A critical moment I'd worried they would fill on the shelves with Easter bunnies in November. Unfortunately Christmas sweets were sold out. What a nightmare!

It seems to be the same all over the world.
