For a start, Easter is celebrated on Saturday and not Sunday. Why? To be honest, I haven't fully understood. (If anyone can fully explain it to me I'd be more than happy to listen.) It is someone linked to the fact they also celebrate Christmas on the 24th of December.
Secondly, the Swedish Easter egg and English Easter egg are slighty different. In the UK we get a lovely selection of chocolate eggs with indulgent treats "oh I shouldn't, but I will" inside. In Sweden however, you get an egg. An actual hard boiled egg. And a brush. And some watercolours. And a smile. You all sit round the table, and paint whatever Picasso, Monet, Hurst, Fresh Prince of Bel-Air design comes into your creative mitts. Not my usual Easter, but great fun all the same.
The Swedish do have their version of a egg full of treats, but it's more like your own nest egg - you fill it with your own pieces of sugary gold.
I love experiencing different cultures. Just don't ask me to drink påskmust!
