You could also write a fanfiction where Naruto's birthday coincides with a major mission. Instead of a traditional celebration, his friends and comrades make the mission a special event. They fight alongside him in a more coordinated and celebratory way, and at the end, they have a small celebration on the battlefield with some local treats they find.
One idea for a Naruto birthday fanfiction could be to focus on a surprise party his friends throw for him. They could all gather at Ichiraku Ramen, his favorite place, and decorate it with symbols of Konoha. Each friend could bring a special gift related to Naruto's journey, like a new kunai set modeled after the ones Jiraiya gave him.
Another approach could be a time - travel fanfiction where Naruto gets to celebrate his birthday with his parents. Minato and Kushina could bake him a cake, and they all spend the day training together. Naruto would learn new techniques from his father and hear stories from his mother about their family.
