A lot of people in Russia celebrate their birthdays starting from a young age.
It is somewhat a tradition - first, parents throw a birthday party for their kids. When these kids grow up and become adults, they have their own birthday parties.
People who work will usually have a small party at their office - they will bring cake and give a piece to every person from their department. A lot of people celebrate birthdays at home too, they'd invite friends and family and have a big dinner with variety of dishes and a birthday cake. Every guest will bring a gift.
Young people like to spend their birthdays outside - for example, in a cafe or going to an amusement park, if the weather is nice.
