I'm in the Catalunya region of Spain.
On 24th most families have a big meal including sopa de galets (giant pasta stuffed with meat, served in broth swimming with morcilla: black pudding). 25th is canelone and prawns.
Presents are delivered by the 3 Kings on the night of 5th January, after a big parade round town with floats and kids dressed as old fashioned goat herders throwing boiled sweets into the crowd - damn they can hurt!
At some point families will do a caga tio 24/25/26th which brings some smaller presents. It's a cheerful log with a beret and a happy face, you keep him warm with a blanket and feed him throughout the month then hit him with a stick while singing a song and he poops presents! Caga = poo.
DH is Basque, but doesn't celebrate anything Basque-esque, he moved away when he was very young. So Catalan traditions aren't connected with either of our upbringings, but we have the Tio for DS, he's bringing a fidget cube, some turron, fuzzy socks and the dvd of Drop Dead Fred this year! Then we celebrate 25th with Father C, we don't bother with Kings.
His mates from school are from many cultures, so there's quite a mix of who does what and when, which is quite nice.
New year's here is pretty big, restaurants full, big family dinners, some fireworks, in bed by 5am!
Its nice that the 6th is celebrated because the whole season of Christmas doesn't just stop on 27th. Schools start back Monday 9th so the holiday is a nice long one.
