Victoria Day is a federal Canadian public holiday, celebrated on the last Monday before May 25, in honour of Queen Victoria’s birthday. The holiday has been observed in Canada since at least 1845, originally falling on the sovereign's actual birthday, and continues to be celebrated in various fashions across the country on the fixed date. When Queen Victoria dies in 1901, Parliament made her birthday an annual holiday.
The date is also, simultaneously, that on which the current reigning monarch celebrates their birthday. It is also Queen Elizabeth 11s’ official birthday, although her actual birthday is April 21st. It is sometimes informally considered as marking the beginning of the summer season in Canada.
The holiday has always been a distinctly Canadian observance.
Happy Victoria Day to all Canadians!
