Computers love uniformity
A minor but annoying thing is if you search 'Islander Day' (the P.E.I. provincial holiday on the third Monday of February) on Google, it helpfully gives you a little 'knowledge' graph above the results telling you that Family Day's date is Monday, February 17, 2025. Mine helpfully has the word Manitoba underneath to tell me this is a holiday in Manitoba where I live. For those of you outside Canada, today isn't a national holiday, but many of the provinces in Canada decided to make a holiday that lines up with President's Day in the US and most of the provinces that did that decided to call that day 'Family Day'. Wikipedia reasonably enough groups these holidays together under a page called 'Family Day (Canada)' but there's no real reason for Google to do so when I search for Islander Day. Islander Day isn't more correctly called Family Day and neither is celebrated in Manitoba like Google told me, it's Louis Riel Day here.
N.B., if you search for Louis Riel Day, it may give you the same knowledge graph, or it might instead give you a snippet from a Saskatchewan culture site telling you Louis Riel day is observed by the Métis on November 16th. the Manitoba Métis Federation now refers to that as Louis Riel Commemoration Day and my location is set to Manitoba, but the Saskatchewan and Ontario Métis nation websites both just call the 16th Louis Riel Day and the Métis have the right here to say which day they observe Riel's legacy.
N.B., it is Family Day in NB
