There are a number of reasons (and ways) that May Day is celebrated around the world, as these comics demonstrate:
Of course, the “real” reason for the holiday is its significance for the labor movement, but that is precisely why it has a somewhat tarnished reputation in the United States…
… especially because of certain militaristic “celebrations” in other parts of the world:
Therefore, since today is not a holiday in the United States, it may be necessary to postpone the celebration:
Comics I Don't Understand 
And some May Day themed cartoons from today’s feeds!
Tra la! It’s May!
The lusty month of May!
That lovely month when ev’ryone goes
Blissfully astray.
Tra la! It’s here!
That shocking time of year
When tons of wicked little thoughts
Merrily appear.
It’s May! It’s May!
The month of great dismay. (from Camelot)
God bless you, Jerry Mendelbaum
Let nothing you dismay
This May you had a rotten month
So what is there to say
Let’s hope next May is better
And good things will come your way
And you won’t have a feeling of dismay
Next May
“Hooray, Hooray! The first of May! Outdoor lovemaking starts today!”
Gordo sang that ditty once. Long before, my father made an annual ritual of somberly reciting it while turning the month on the refrigerator calendar. I am told some substitute another word for “lovemaking”.
I learned this as the “eighth of May” and “outdoor fornication day,” but isn’t May eighth Mother’s Day? 😬 Creepy. In fact, May First celebrates sacred union in all its forms, including the “Unions” form, I suppose. Yay, five day work-week! Thank you, old union organizers! Wonderful, thoughtfully curated post!
Catchy psychedelic rock tune…
If there’s a bustle in your hedgerow, don’t be alarmed now
It’s just a spring clean for the May Queen
That was a mondegreen for me for years. I thought it was “It’s just a sprinkling for the bake queen.”
Even though in the UK 1st May is not a holiday unless it’s the first Monday in May, which is a holiday, and even though that holiday is called the “Early May” holiday, not “May Day”, we’ve twice had right-wing governments suggest cancelling it and replacing it with Trafalgar Day (21st October)
For a number of years when I was in high school and college I campaigned heavily to having my birthday celebrated on May 1. No one would agree to it and I finally gave up – both trying to change my birthday to same and celebrating my birthday at all.
Robert, my husband, hates that I don’t allow any celebration of same – no party, no dinner, no gifts, no Trick or Treating – ahah and now the reason is revealed! I hate having Halloween as my birthday and have done so since I was a child. Since there is no April 31, I had picked May 1 as the alternate – but this to day I am telephoned by my sisters and mom to wish me happy birthday on Halloween and my chosen day is ignored by all – when it is the actual day I want to have ignored.
Or as I say when I say when I say I hate my birthday – “it is the not the years, it is the day!”
