A coworker pointed out that tomorrow is Republic Day in India, since some of us work with teams based there. It made me wonder how many national holidays there are in the world that are based on kicking out the British.
Not Canada.
April 17, 1982 was the date the British lost any authority over Canada for good.
It’s a regular day.
Fourth of July in the US. Just to get it out there.
Today (26th) is also Australian Day, where we celebrate the first fleet from the UK arriving in Sydney. Make of that what you will.
Botswana - September 30 - Boipuso (aka Independence Day) - anniversary of 1966 independence
Kenya - December 12 - Independence Day - anniversary of 1963 independence
Malaysia - August 31 - Independence Day/Malaysia Day - anniversary of the 1957 independence of the Federation of Malaysia (the colonies of Sarawak and North Borneo would later be incorporated into Malaysia and the modern nation of Malaysia dates its creation from September 16, 1963)
You’re unlikely to find those days in the Commonwealth kingdoms (or “realms”), as the posters from Australia and Canada have already said. That’s because “kicking out” the British cannot really be pinpointed down to a specific day. Rather, the process of these countries gaining increasing autonomy and, ultimately, independence was a very gradual one, often stretching over many decades. First they would get responsible government as a colony, then dominion status (a kind of almost-quasi-independent colony that was, notionally, still part of the British Empire), then there were several steps in the development of dominion status that further increased this autonomy. To some extent these countries haven’t fully “kicked out” the British to this day, as the shared monarchy shows, although the countries operate, of course, fully independently.
This applies to the already-mentioned countries of Australia and Canada, and in addition also to New Zealand and some Caribbean and Pacific Ocean islands such as e.g. the Bahamas.
Ghana’s independence day is March 6th.
Even though Ghana is a member of the commonwealth, the spirit of the holiday is very much celebrate the end of British rule and assumption of independence.

To be clear, Republic Day in India “honours the date on which the Constitution of India came into effect on 26 January 1950 replacing the Government of India Act (1935) as the governing document of India and thus, turning the nation into a newly formed republic.”
Whereas Independence Day in India (August 15) is “a national holiday in India commemorating the nation’s independence from the United Kingdom on 15 August 1947, the day when the provisions of the 1947 Indian Independence Act, which transferred legislative sovereignty to the Indian Constituent Assembly, came into effect.”
Republic Day in India is closer to an equivalent of September 17 in the US.
What is September 17 in the US? 
Israeli Independence Day. On May 14 1948, the day the last British troops left Haifa harbor and the Mandate was dissolved, David Ben Gurion and the provisional Government declared independence. It’s celebrated on 5 Iyar each year, and it’s a really big deal - at least as big as the 4th of July in the U.S.
sigh, all of those calls to remember 9/17 gone unheeded.
The day the US Constitution was adopted. Obviously not a widely celebrated day. Republic Day in India is celebrated, though. The OP seemed to imply that it was India’s Independence Day, but it’s not.
It is, of course, the day that Joshua A. Norton declared himself “Norton I, Emperor of the United States” in 1859.
No one celebrates that anymore?
In Australia we celebrate the day when the country became subject to the British, reduced to colonial status, and operated as an open prison.
Why, yes, since you ask; this is a matter of current controversy.
(The day on which the colonies united into the Commonwealth of Australia, and achieved [a degree of] independence, was 1 January, which was already a holiday.)
Perhaps once Australia eventually formally separates entirely from the Crown the then-leadership, armed with a real sense of historical irony, can arrange to sign the Articles of Republic or whatever they’ll be called on Jan 26.
That way everyone can celebrate that day, but disagree over what they’re celebrating and why. 
Late add:
While we’re discussing holidays, I got to wondering about a source for world holidays, and how far I’d have to stretch to celebrate something, if only with a toast, every day of the year.
This site looks fairly promising as a source. Scrolling down a bit I see …
I don’t know what Sri Lankans will be doing tomorrow (Thu) on “Duruthu Full Moon Poya Day” but it sounds like a promising excuse for a party! 
This is what I was going to say. Indian Independence Day is August 15.
To put Republic Day in simpler terms, it’s the day that India became a republic, that is, not a hereditary monarchy.
Before Republic Day, India was like Canada or Australia. India’s head of state was the British monarch represented by a viceroy/governor-general.
After Republic Day, India’s head of state is a non-hereditary president.
Nah, we need a national public holiday in the spring. There are five between January and April, and then nothing until December.
When the time comes to storm the Bastille, overthrow the aristos and proclam the republic, we should definitely make sure it happens in October.
It should be noted that that is not the day the US actually kicked the British out. Instead it was the date someone wrote at the top of the complaint form, which led to the formation of a committee (headed by one G. Washington) looking into the possibility of altering the dependency status some time in the future.[*]
If you want the day the British were actually kicked out of the US, consider September 3 or October 19.
[*] Technically, the committee already existed, the complaint form just changed its purpose.
