(CNN) — India is the world's largest democracy, and it's serious about its constitution. The country pulls out all the stops to celebrate its remarkable achievement in self-governing each Republic Day.
The biggest focus is on New Delhi's impressive annual military and cultural parade, but this national holiday is celebrated far and wide.
Anyone who plans to travel to India during Republic Day can expect some potential transportation delays and various business closures, especially in Delhi. But you can be promised an amazing spectacle you won't soon forget. First, a little history:
What is Republic Day?

India freed itself from centuries of colonial British rule in August of 1947. They began work on new governing document for the sprawling nation, and it was adopted in November 1949.
But it wasn't until January 26, 1950, that its new constitution went into effect.
And from that first January 26 onward, the country celebrates with Republic Day. In 2019, that date falls on a Saturday.

You'll see displays of India's military prowess with tanks, weaponry and precision marching by armed forces members in their finest uniforms. It's not just a military display, though.
You'll also see elaborate floats and groups of people representing India's almost unfathomable variety of cultures, religions and climates.
You can watch everything from floats saluting the country's seafaring heritage and native land fauna such as elephants, monkey and tigers to beautiful displays reflecting India's many religions -- Hinduism, Islam, Buddhism and more.
It's a jubilant free-for-all as floats pass by with boxers and acrobats, often followed by dancers in colorful, swirling costumes.
VIPs join the masses

This is also an international celebration, with dignitaries from around the world attending. Former US President Barack Obama went in 2015. Back at the first Republic Day in 1950, chief guest was Indonesian president Sukarno.
Where is Delhi's parade held?

The route is more than 5 kilometers (3.1 miles) long, and it follows the Rajpath, one of the country's most celebrated roadways.
It starts near the Presidential Palace, passes through the famed India Gate and winds up around the Red Fort.
The Rajpath is lined with lush green spaces, trees and canals. (Travel hint: If you aren't in the city for the parade, the Rajpath is worth a visit any time of year). The parade lasts about three hours and starts at 9:30 a.m. local time after a ceremonial hoisting of the Indian flag.

What about the rest of the nation?
