In the movie "V for Vendetta," what is the date that masked vigilante "V" urges people to remember?

In the movie "V for Vendetta," the masked vigilante V urges people to remember the date November 5th because it marks the anniversary of the Gunpowder Plot in 1605. This infamous event was a failed assassination attempt on the British Parliament and King James I by a group of English Catholic conspirators led by Guy Fawkes. By choosing this date, V aligns himself with the historical figure of Guy Fawkes, who has become a symbol of resistance against oppressive governments and the fight for individual freedom. V aims to spark a revolution against the totalitarian regime in the movie, and November 5th serves as a significant day to remember the consequences of political tyranny and the power of ordinary citizens to rise against it.
