This is relevant here in Chicago. Probably because it's the city with the second largest Polish population outside of Warsaw. Also paczki are pretty tasty.
Día de los Muertos, because of the amazing art at the very least. Plus, who wouldn't want a second Halloween of sorts? (I know the reasons to celebrate are very different)
Also, Earth Day and Arbor Day, because our trees and planet are awesome.
in elementary school we had Old-Fashioned Day when everybody brought their grandparents to school and wore short pants and played marbles and panned for gold like the "olden times". I was super excited to chase a hoop with a stick only to learn that it's pretty fucking boring.
we would have a special lunch with the grandparents, where we'd give them all handmade cards. and a special assembly with them, in an auditorium, where they could sit down of course.
Maybe "wish" isn't a fully accurate word, but I have a few that come to mind.
Sibling Day. Like Valentine's Day, Father's Day, or Mother's Day, but for your siblings. I have had a fluctuating bond with my siblings and this would've been a nice thought.
Friendship Day. We technically celebrate it, but in a rather underwhelming way. There's an annual "friendship festival", but when you go there, they say something like "happy day of friendship between our nation and our Northern neighbors", so it's in a different sense. Might as well go the whole way.
Deganawida Day. This one requires explaining. One day from now, 882 years ago, a great nation here was founded, an empire of righteousness, health, and power. It was of course conquered, but it still culturally resonates. The name of the holiday would be after its founder and the form of celebration would be similar to a day of interpersonal goodwill and local patriotism. Considering the way society is, it would be a nice fix. If added to the calendar, it would also give the lonely month of August its own holiday.
Michaelmas. I grew up with Michaelmas. I still observe it. Why do we shirk it? Cuz some guy who famously nailed a decree on a church door said so? I'm more annoyed people actively avoid it.
Hawaiki Day or whatever you want to call it. I'm surprised we have a day of the year for Christopher Columbus because the Italians voted it in and one for Leif Erickson because the Norse-loving folk voted it in and not one for the Polynesians who discovered South America before the Vikings discovered North America. It's only fair.
National Test Your Backups day. So much time and money lost because people either don't backup their data or assume they have when they have not. (Ok it's not a real holiday but it should be)
There are over 2 million Franco Americans in New England alone. And yet, I seem to be one of the few who remembers our history, nevermind our language. This is not an indictment, we've had to adapt to survive and avoid persecution.
But still we're allowed to be proud, we're allowed to be seen, and I'd love to live long enough to see our diaspora celebrate our roots and our present on both sides of the border
Whilst I don't want to argue about whether the appreciation of people in your life should be encouraged by a celebration day, I would like to point out that holidays aren't specific to appreciating people . They can also be for appreciating things , such as natural phenomenon.
Personally I'd prefer winter and summer type celebrations on the equinox and solstice than Christmas and a seemingly random (in my country) public holiday at a point in the summer where it isn't that warm anymore.
