Most of the world celebrates it on 1st May.
According to https://www.norden.org/en/info-norden/public-holidays-greenland May 1st in both International Workers Day and Anniversary of introduction of home rule. These are not public holidays, but provide time off under collective bargaining agreements. So Greenland should be striped Red, Green, Gray and one more color.
We celebrate ours on a different date in Australia because we got were the first in the world to get the 8 hour working day.
In mostly countries its called “worker day”, labor day its used firstly in USA goverment for no respect the associate worker right
In the US, May 1 is “Loyalty Day”, as it has been since the McCarthy era
In that context it means employee loyalty.
Hmmmm, I wonder why they changed that
Japan has 勤労感謝の日 which is typically translated as “labor thanksgiving day” in English and is 23 November this year. We have no national public holiday on May 1st this year. I think it’s possible for some of the Golden Week holidays to fall on the 1st technically, but I’m not 100% sure on that.
May 1st colour being red is a nice subtle touch.
There’s another observance on the first of May I learned from Jonathan Coulton
My wife (bless her sweet heart) for years thought the song said “outdoor cookin’ starts today”.
I always wonder how a commentation of something that happened in Chicago is celebrated around the world but not in the US
