5 pointers on social media holidays trends that hold up
Five pointers on social media holidays trends that hold up, from unpriced declarations to the smaller owned calendar that beats any crowded national day.
The calendar only grows. Nothing removes a day once declared, and several parties gain from adding one. Attention does not grow with it, which is why joining in feels more obligatory and pays less each year. The five pointers on social media holiday trends here describe supply rather than taste.
Two real entries show the range. Pi Day on March 14 was first marked in 1988 at the Exploratorium in San Francisco by the physicist Larry Shaw. Talk Like a Pirate Day on September 19 began in 1995 as a joke between John Baur and Mark Summers in Oregon.
What to take away
- Declaring a day costs a press release and nothing else, so the count rises every year and the average day is worth less.
- Nothing retires a day, and a listing that stopped working in 2019 still appears on 2027 calendars.
- Whoever declares captures the benefit, while aggregators gain because coverage is their product and the accounts that participate hardest usually gain least.
- Judge a day by your own results on the same date across years, not against other accounts.
- Build a calendar you ownyour own anniversaries, your field's real dated events, two or three external days with provenance.
Pointer 1: the supply is unpriced
Anyone can announce a day. A company, a trade body, a single person with a press release. There is no application, no scarcity and no gatekeeper for the informal kinds.
That is why the origins of a day sort into six kinds and only the top three carry any process at all. The rest cost nothing to create and nothing to keep.
Two declarations show how cheap the entry is. American Express started Small Business Saturday in 2010, the Saturday after Thanksgiving. The 92nd Street Y in New York and the United Nations Foundation started Giving Tuesday in 2012, the Tuesday after Thanksgiving.
Pointer 2: nothing retires
No one is responsible for retiring a day nobody observes. It sits in aggregator listings years after the last participant cared, because deleting a row benefits nobody who holds the list.
A day that stopped working in 2019 still appears on 2027 calendars. The listing is not evidence that anyone marks it.
Two catalogs keep those rows alive. Chase's Calendar of Events has been published every year since 1957 and carries more than 10,000 entries, sponsor contacts included. National Day Calendar, based in Mandan, North Dakota, lists more than 1,500 days and takes new submissions on its website.
Pointer 3: the asymmetry funds it
The declarer gets an annual occasion built around their subject that other people promote for free. The cost lands on everyone else as a slot they feel they should fill.
That is a plain perverse incentive: the reward is concentrated, the cost is diffuse, and nobody has to behave badly for it to work.
Record Store Day, first held on April 19, 2008, hands independent record shops a date that labels and collectors promote at no cost to the shops. Free Comic Book Day, run on the first Saturday in May since 2002, gives comic shops the same arrangement.
The competition is for attention rather than budget. Adding a day does not dilute a spend; it dilutes the reader's willingness to care, and that pool is fixed.
The attention economy describes the general form of that constraint. Whether one date deserves a slot from that pool is settled case by case in six worked situations.
Pointer 4: the crowding is measurable
The crowding is measurable
| Year over year | What happens | Effect on you |
|---|---|---|
| More days declared | The calendar thickens | Any given day is less distinctive |
| More participants per popular day | Crowding on the best dates | Your post competes with identical posts |
| Aggregators list everything | Provenance becomes invisible | Selection costs more effort each year |
| Audience exposure rises | Themed posts read as routine | The response to a themed post falls |
| Your own history | Comparable only against yourself | Google Trends and Google Analytics 4 line the same date up across years |
Watch the last row of the shifts on your own numbers. If themed posting has weakened over several years, you probably did not get worse at it.
Year-over-year effects of crowding
What happens
- More days declared
- Calendar thickens
- More participants
- Crowding on best dates
- Aggregators list everything
- Provenance invisible
- Audience exposure rises
- Themed posts routine
Effect on you
- More days declared
- Day less distinctive
- More participants
- More identical posts
- Aggregators list everything
- Selection costs more
- Audience exposure rises
- Response falls
The format has become ordinary. That is a market condition, not a performance problem, and trying harder will not fix it.
Four tools make the check cheap. Google Trends sets the range to the same weeks in different years. Google Analytics 4 has a compare option that places last year's matching dates beside this year's. Meta Business Suite exports reach and engagement per post. Buffer and Hootsuite keep every queued post on one calendar view.
Pointer 5: build a smaller calendar you own
Your own anniversaries, your field's real dated events, and at most two or three external observances with genuine provenance and genuine adjacency to what you do.
That calendar is uncrowded, because nobody competes for your anniversaries. It is stable, because a historical date does not get retired. And it is defensible, because you can say why each entry is on it. The social media holidays overview reaches the same conclusion from the other direction.
Bloomsday on June 16, drawn from James Joyce's Ulysses and marked in Dublin since 1954, belongs on a publisher's list. Towel Day on May 25, run by Douglas Adams readers since 2001, belongs on a science fiction bookseller's.
Earth Day on April 22, first held in 1970, and International Women's Day on March 8, marked by the United Nations since 1975, have provenance that small days lack.
Who benefits from the crowding
Aggregators do, because coverage is their product and thickness is coverage. National Day Calendar, National Today and Days of the Year all carry advertising beside the listings they hold. Declarers of popular days do, because participation is promotion.
Nobody else does. The operations that participate hardest usually have the least to gain, since a crowded date rewards whoever the audience already knows. The pressure to join is framed as an opportunity, and it is one, for somebody. Working out who is a faster route to the decision than analyzing the day itself.
Common questions
Will the growth ever stop?
Not through any mechanism now in place. It could stop mattering if audiences discount themed posts enough that declaring a day stops paying. That would be a change in response rather than supply, and you cannot observe it from outside.
Should I drop themed posting entirely?
That is defensible and cheaper than most alternatives. Keeping two or three dates with real adjacency is usually better, because it retains the occasions where you had something to say.
Is a crowded day ever worth entering?
When you can take an angle the crowd will not, which usually means declining to celebrate and explaining why. That is a different piece from a themed post and it competes in a much emptier field.
How do I know if a day is getting more crowded?
Compare your own results on the same date across years, with the seasonal confound removed. Google Trends and Google Analytics 4 hold several years of your own data on that date. Comparing your result against other accounts tells you nothing, because you would be comparing audiences rather than dates.
