What this article is

Victoria Day is a federal Canadian public holiday observed on the last Monday preceding May 25 to honour Queen Victoria, who is known as the "Mother of Confederation". The holiday has existed in Canada since at least 1845, originally on Victoria's natural birthday, May 24. It falls on the Monday between the 18th and the 24th (inclusive) and, so, is always the penultimate Monday of May. Victoria Day is a federal statutory holiday, as well as a holiday in six of Canada's ten provinces and all three of its territories. The holiday has always been a distinctly Canadian observance and continues to be celebrated across the country. It is informally considered the start of the summer season in Canada.

How this was measured

Views are Wikimedia's own pageview counts for en.wikipedia, filtered to agent=user so automated traffic is excluded. The baseline is the median of the previous 60 days, which is used instead of the mean so that an earlier surge cannot flatten a later one. The multiple is the day's views divided by that median.
