Held annually on 9th August, the National Day Parade (NDP) is an annual parade where Singaporeans from all walks of life come together to commemorate our nation's independence. From the spectacular aerial displays by the Republic of Singapore Air Force, to the precision drills by our uniformed groups and the lively performances by thousands of passionate participants, NDP showcases the best of Singapore's spirit and achievements.

The Story Behind Singapore’s National Day

National Day is a vibrant cultural street parade featuring dazzling floats and performances, celebrating our nation's heritage and multiculturalism. It’s this unity, despite our differences, that drives us forward, fostering a sense of belonging among all Singaporeans. It’s a moment to reflect on the resilience and determination that have shaped Singapore into the powerhouse it is today.

As evening falls, Singapore's skyline comes alive with dazzling light displays. The National Day light-up is an unforgettable sight, with the iconic Marina Bay Sands and Merlion illuminated in red and white, reflecting the pride and joy of our nation. The streets are filled with cheerful crowds and vibrant decorations, making it the perfect time to soak in the festive atmosphere.

And of course, no National Day celebration is complete without the iconic fireworks display. As the night sky is illuminated with vibrant bursts of colour, the dazzling fireworks symbolize the joy and pride that fills the hearts of all Singaporeans.

Want to know how fireworks work?

Fireworks are made with science! When the firework shoots up into the sky, it's because of a special powder inside that creates a big push. The bright colours in fireworks come from special metals and chemicals. Scientists learnt how to mix them to make all the beautiful colours we see in the sky! The beautiful colours you see come from different metals burning up - just like how your gas stove has blue flames. Some metals burn red, others burn green or blue. That's why we get such pretty colours lighting up the sky during National Day! (Find out more in detail how fireworks work here!)

As we celebrate National Day 2025, let’s take pride in how far we’ve come, honour the diversity that makes us strong, and look forward to a bright future. Together, we are Singapore!
