Strange, Unusual, & Weird September Observances

Each and every month of the year, MamaNYC features a long list of the strangest and wackiest holidays and observances. Last month, I shared some bizarre holidays with all of you, which included Sewing Machine Day AND Hug Your Boss Day! Today I am back with a list of the strangest and weirdest September holidays that you will NOT believe! These lists don’t seem to get any shorter, but rather include well over 200 of the oddest, weirdest, and most bizarre observances you could ever imagine!

Keep in mind, while a large majority of these holidays are seemingly humorous, I also include many that are actually serious or nationally recognized holidays. This list will basically help you get by throughout the entire month of September without skipping a single day, week, or month without a reason to celebrate. Feeling down? Why not throw yourself an ice cream party on September 22nd (Ice Cream Cone Day), or keep yourself busy researching the list of banned books during "Banned Books Week" (September 22-29; last week of the month)?!

My name is Nicole Napolitano and I am a full-time professional parenting blogger and work-at-home mom of two adorable and vivacious children (boy - 6 & girl - 2.5). I decided to develop MamaNYC in 2010 shortly (1-month) after transitioning from work-a-holic Internet marketing pro to the shoes of a stay-at-home mom (bored!). As a dedicated business manager for over 9-years, I was determined and positive that I would once again be a successful business woman -- whether or not I had a diaper bag tagging along! I am a New York City native, but relocated with my husband and our two kids to sunny Los Angeles in the summer of 2014. Leaving everything behind was scary, but it's time to make new memories. My interests include web design, Internet marketing, product development and research, SEO, movies, friends, and spending time with my family.

  1. My mother actually has had Celiac disease for over a decade…before gluten free anything was really available. I never knew till I read through this list that a day existed for it. I will have to make her a g-free dinner in celebration.

  2. P.S. By “her” I mean Mortimer. Yes. I get that’s a boy’s name. Don’t judge me.

    I also think it would be quite appropriate to celebrate National Lazy Mom’s Day by lying on the couch and munching on a stick of salami, which also gets Salami Day out of the way.

  3. This list is great. I laughed when I read the observance of Chili Peppers and Figs Month. Also glad for the awareness of Build A Better Image Week: 16-22, Prostate Cancer Awareness Week: 16-22, Pediatric Cancer Awareness Month, National Skin Cancer Awareness Month …as well as all of the Cancer awareness reminders.

  4. Thanks for this list! I had no idea there were so many holidays this month. My favorite would have to be the be kind to editors and writers month because I am a writer.. 🙂

  5. That are some lists of September holidays and observances! That this month have more than any other months? I giggled at some of them like the Hobbit Day (hobbits aren’t even real creatures so what is it that you use that day, read the book? Lol although I did love the book in high school though) Another funny one was the punctuation day. I think we should let everyone one when punctuation day is and that’s the only day they can correct us on Facebook or twitter. I believe they shouldn’t do that any other days because who wants to be corrected by the punctuation police? Thanks for sharing, this was fun to read and a little of trivia that I’m sure not any of us who read knew about!

  6. I’m back to see what wacky holiday is today. Actually today’s holidays are reasonable (except perhaps for drive you Studebaker) There are a lot of fruit and veggies celebrated this month – perhaps the beginning or end of a harvest.
