105. The different Hogwarts houses celebrate birthdays differently:

Hufflepuff: 

• On their birthdays, the Hufflepuffs get woken up with cake in bed before breakfast
• The night before the other students prepare the celebration and the cake, and they visit the kitchen for ingredients
• The Hufflepuffs make sure to never forget any birthday, and it’s a priority to celebrate every birthday equally much, even for students who are not their closest friends
• The students who have their birthday in summer or during the Christmas break gets celebrated when they come back in autumn, no one is forgotten
• The student is presented with little surprises throughout the day, like all the portraits wishing them a happy birthday 

Gryffindor: 

• The Gryffindor students have the loudest celebrations
• The day starts with all the other students in their dormitory singing happy birthday
• During the day the students will randomly burst into song, and they can be heard singing everywhere in the castle
• The birthday girl/boy/person is sometimes given a crown or hat to wear during the day, and every time they see someone wearing one, they all start singing
• Once, Fred and George Weasley enchanted the statues and suits of armour in the school to sing every time she/he/they walked by
• The singing always drives the professors crazy, and all except Dumbledore, Lupin and Hagrid give out detentions to anyone who sings in their class 
• “You’re SO OLD!!”

Slytherin: 

• The Slytherins plan their birthday celebrations for a long time, with organised teams within the house for each part of the celebrations, like music, cake, decorations etc.
• It’s important for the Slytherins to throw the perfect birthday celebrations, and the students pride themselves in having the best parties and surprises
• Every student gets their own little party, sometimes with only their closest friends and sometimes with almost every student of the house
• The parties are often supposed to be surprises
• But the birthday girl/boy/person almost always figures it out beforehand
• Every student gets a personalised verse of happy birthday or their own short song, prepared by the students in the “song group” 

Ravenclaw: 

• Every birthday the birthday girl/boy/person has to complete a treasure hunt, and are given clues and riddles to find the treasure throughout the day
• The clues are given written down on pieces of paper or in other magical ways
• Each riddle leads to another clue and they eventually lead to the treasure that is hidden somewhere on the grounds or in the castle
• The treasure varies for each student and is personalised for that specific person by their friends
• The students of Ravenclaw always makes sure to prepare small but clever surprises for birthday girl/boy/person to discover throughout the day, all leading up to the big gift
