When is Your Independence Day? Can you play the your Anthem? (Patreon)

This last weekend was a Colombian holiday celebrating a pivotal battle in the fight for independence, and subsequently independence was achieved the following month with Colombia declaring itself a sovereign nation on July 20th, 1810. 

So, two part question. 

What is the date of Independence for your country? (Please leave the name and date in the comments)

and... drum roll... can you play your National Anthem on the Ukulele?
