In my country, they do not focus on more. It is just like normal day, except getting one year old. We usually do it for kids,kids like it a lot. We invite their freinds to home, sometimes we make homemade cake, and kids get charming to help with doceration. We buy ballon and candle, we celebrate all together with their freinds, and sometimes their friend parents also attend. So kids enjoy a lot and have fun. On the other hand, sometime we celebrate it for adults too. Maybe going to a restaurant or cafe with some freinds and family members. Everuyone also present gift to a person who we gathered to celebrate his/her birthday. We enjoy and having a deep conversation togather. It is especial day, I think by celebrating someone birthday is nice approach, we make the person happy.
