17 August is independent day of Indonesia. Indonesia was born at 17 August 1945 when Mr Soekarno proclaims the independence of Indonesia. Since then, we always celebrate 17 august as independent day.
Usually there are parties of independent day. Those parties are such kind of traditional contest. Example of contest are sack race (balap karung), eat cracker (makan kerupuk), etc. We really enjoy this event. People or especially kid are very happy with the contest.
In other case, at school or at state office, we celebrate it by ceremony of raising bendera merah putih (national flag of Indonesia). This ceremony is meant to respect the heroic struggle of national war.
Happy Birthday for my beloved Country
