You've come up with a national day for your brand. You have the name. You have the date. You're ready to make it official.
Now comes the confusing part.
There is no single authority that governs national days. No government agency stamps your application. No universal registry exists. Instead, there are half a dozen platforms — each with different costs, different audiences, different acceptance criteria, and different levels of credibility.
Some are free. Some cost thousands. Some approve nearly every submission. Others accept fewer than 30 a year out of 20,000 applications.
Choosing the wrong platform wastes money. Choosing the right one gives your holiday an audience from day one.
This guide breaks down every major registration platform available in 2026. What they cost, how they work, who they reach, and which ones are worth your time.
The Landscape: What "Official" Actually Means
Before we compare platforms, let's clear something up.
There are only 11 federal holidays in the United States. Congress creates those. Your branded national day will not be one of them. That's fine. It doesn't need to be.
The Washington Post cataloged over 5,700 national days in the U.S. Almost all of them are unofficial. They were created by companies, nonprofits, trade associations, and individuals. They exist because someone registered them on a platform, promoted them, and got people to participate.
"Official" in this context means listed, discoverable, and recognized by the media. That's what registration gives you. Not a government seal. Something better: an audience.
Here are the six platforms that matter.
1. Holiday Calendar (holidaycalendar.io)
The Overview
Holiday Calendar is one of the largest holiday discovery platforms in the world. Over 80 million people visit the site each year. That traffic is driven by a simple question millions of people Google every day: "What holiday is today?"
The platform lists over 5,000 global holidays. Journalists, content creators, social media managers, and brands all use it to discover and verify holiday dates.
Holiday Calendar offers two paths to registration. You can submit a holiday for free and let the community vote on it. Or you can use a paid package for guaranteed listing with built-in promotion.
What It Costs
Free submission: Submit your holiday and let the community decide. No cost. No guarantee of listing.
Holiday Creation Package — $2,500: This is the starting tier for brands that want guaranteed results. It includes custom holiday creation, a dedicated email announcement to 325,000+ subscribers, one year of sponsorship on the platform, a do-follow backlink to your website, and prominent placement across high-traffic pages.
Custom packages are available for brands that want more. Add-ons include consumer surveys of 1,000–3,000 respondents to generate data hooks for media coverage, data visualization and infographics, and individual pitching to 10,000+ verified media contacts who have opted in to receive holiday news.
The Timeline
Basic holiday creation can be completed in as little as one week. If you add promotion and media coverage, the process typically takes three to four weeks.
Who It's Best For
Brands that want discoverability. The 80 million annual visitors make this platform one of the most effective ways to get your holiday in front of real people. The email list of 325,000+ subscribers means your holiday gets an announcement to an engaged audience on launch day.
The do-follow backlink is also a meaningful SEO benefit that most other platforms don't offer.
Strengths
- Massive organic traffic (80M+ annual visitors)
- Built-in email promotion to 325K+ subscribers
- SEO-friendly with do-follow backlinks
- Fast turnaround (as quick as one week)
- Optional media pitching and survey services
- Free submission path available
Limitations
- Paid packages start at $2,500
- Free submissions are community-moderated with no guarantee
2. National Day Calendar (nationaldaycalendar.com)
The Overview
National Day Calendar is one of the most recognized names in the national day space. It maintains a large database of holidays and has a dedicated editorial team — called the Registrar — that reviews submissions.
The platform is selective. Very selective.
What It Costs
Free. There is no charge to submit a holiday to National Day Calendar.
The Process
You fill out an application on their website. The application asks for details about your proposed holiday: the name, the date, the purpose, and any supporting information like websites, social media channels, and media coverage.
The Registrar committee reviews every submission. They receive over 20,000 applications per year. They approve roughly 30.
That's an acceptance rate of about 0.15%.
If your holiday is approved, you'll receive an email with instructions. If it's not, you won't hear back. After six weeks of silence, you can assume the committee passed.
The Timeline
Submit at least six weeks before your desired date for digital inclusion. For the printed calendar, your application must be in the finalization phase by November 1 of the preceding year.
Who It's Best For
Organizations with an established track record. If your holiday already has some organic participation, media coverage, or community support, National Day Calendar is a credibility stamp worth pursuing. But if you're starting from scratch, the odds are not in your favor.
Strengths
- Free to submit
- High credibility when accepted
- Well-known and widely referenced
- Established editorial review process
Limitations
- Extremely low acceptance rate (~0.15%)
- No notification if rejected
- No promotional support included
- Long review timeline
- No paid path to expedite or guarantee listing
3. Chase's Calendar of Events
The Overview
Chase's Calendar of Events is the oldest holiday reference in the United States. It has been published annually since 1957, currently by Rowman & Littlefield. Libraries, newsrooms, and event planners have used it for decades.
This is a printed book, not primarily a website. That distinction matters. Inclusion in Chase's means your holiday is listed in a physical reference that journalists and researchers pull off the shelf.
What It Costs
Free. Chase's does not charge for submissions.
The Process
Submit through their online form. The form asks for details about the event, your contact information, and a mailing address.
Once you submit, you'll receive an email acknowledgment. During May and June, the editors will notify you of acceptance or rejection. Not all submissions are selected. Inclusion is at the editors' discretion.
Important: Chase's does not accept birth anniversaries, historical anniversaries, celebrity birthdays, or workshop/seminar submissions.
When you submit, you agree to provide updated information about your event annually for as long as it exists. This is how they keep the calendar current.
The Timeline
The deadline for next year's edition is April 15. So if you want to appear in the 2027 book, your submission must arrive by April 15, 2026.
Who It's Best For
Brands and organizations that value legacy credibility. Chase's carries weight with traditional media. If you're pitching your holiday to newspaper editors or broadcast producers, a Chase's listing gives you a reference point they already trust.
Strengths
- Free to submit
- Longest-running holiday reference (since 1957)
- Strong credibility with traditional media and libraries
- Legitimate editorial review process
Limitations
- Print-first format limits digital discoverability
- No promotional support
- Annual deadline (April 15) means timing is rigid
- No website listing drives traffic to your holiday
- Editors' decisions are final with limited transparency
4. National Today (nationaltoday.com)
The Overview
National Today positions itself as a holiday media company. It combines a holiday calendar with editorial content, survey data, and brand sponsorship opportunities. The site draws about 5 million monthly visitors.
More than 10,000 media outlets reference National Today. Their journalist network includes outlets like the Today Show. They also work with 2,500+ influencers and bloggers.
National Today offers two services: submitting a new holiday, and sponsoring an existing one.
What It Costs
Creating a new holiday through National Today costs approximately $5,000. Sponsoring an existing holiday is also available, though pricing varies.
Sponsorship lasts 12 months. It includes a tailored holiday page with your branded messaging and an email update to 350,000 subscribers. Additional featured content can be purchased on top.
The Process
National Today has a dedicated team of holiday specialists. You submit your proposal, and they review it on a case-by-case basis. They consider brand-new holidays that don't have an established track record, but preference goes to holidays with existing community support.
Who It's Best For
Brands that want a media-first approach. National Today's strength is its distribution network — media outlets, influencers, and a large subscriber base. If your goal is press coverage and influencer amplification, this platform is designed for that.
Strengths
- Large media network (10,000+ outlets)
- Built-in influencer distribution (2,500+ creators)
- Email list of 350K+ subscribers
- Holiday sponsorship includes branded editorial content
- 5M monthly visitors
Limitations
- Higher cost ($5,000+ for new holidays)
- Pricing not fully transparent on the website
- Case-by-case approval process
- Sponsorship is time-limited (12 months)
5. National Day Archives (nationaldayarchives.com)
The Overview
National Day Archives takes a different approach. It's essentially a registry with tiered packages. You pick a name, pay a fee, and receive a certificate and listing.
The platform is the most accessible option for people who want a guaranteed listing without an editorial review process.
What It Costs
Three tiers:
Proclamation — $149 A certificate and social media asset. Your holiday is not listed on the Master Calendar that goes to media. Think of this as a personal keepsake — naming a day in someone's honor, for example.
Standard Listing — $995 Your holiday gets listed on the Master Calendar, which is distributed to media outlets. You receive a permanent web page on the site with your name as the registrant. You choose from 50 available category names. You also get a certificate of registry.
Premium Listing — $2,495 Everything in the Standard tier, plus access to exclusive premium naming categories. You get reserved premium names that aren't available at the Standard level.
The Process
Fill out the online form. Verify your information. Pay the fee. That's it.
There's no editorial review board. No months-long wait. No risk of rejection (assuming your chosen name is available).
Who It's Best For
Individuals or small organizations that want a quick, guaranteed listing. The Proclamation tier is popular for personal celebrations — naming a day after a loved one, for example. The Standard and Premium tiers serve brands that want media distribution without the uncertainty of an editorial review.
Strengths
- Guaranteed acceptance (no editorial gatekeeping)
- Fast and straightforward process
- Multiple price points for different needs
- Permanent listing included
- Media distribution at Standard tier and above
Limitations
- Lower perceived credibility due to open acceptance
- No built-in promotional support beyond the listing
- No organic traffic driving discovery
- Certificate-based legitimacy may feel thin for larger brands
6. Days of the Year (daysoftheyear.com)
The Overview
Days of the Year is a UK-based platform that catalogs holidays from around the world. It's been running since 2012 and has a strong social media presence.
The editorial team focuses on holidays that are fun, weird, and shareable. The tone is lighthearted. If your holiday has a playful or community-driven angle, this is a natural fit.
What It Costs
Free. There is no charge to submit a holiday.
The Process
Submit your holiday through their website. The team receives hundreds of applications each month. They review submissions based on proven popularity, existing community activity, humor, and general interest.
They generally list events that already have a community of people celebrating them. If your holiday is brand-new with no track record, approval is less likely.
Who It's Best For
Brands and creators with an existing community around their holiday. If people are already celebrating your day informally and you want additional visibility — particularly in international markets — Days of the Year is a good supplementary listing.
Strengths
- Free to submit
- International audience (UK-based with global reach)
- Strong social media presence
- Good for lighthearted and community-driven holidays
Limitations
- Preference for holidays with existing traction
- No promotional packages or paid options
- No guaranteed acceptance
- Smaller audience than U.S.-focused platforms
The Comparison Table
Here's every platform side by side.
| Platform | Cost | Acceptance | Audience Size | Promotion Included | Best For |
| ------------------------- | ------------------- | ------------------------------------------ | ------------------------------- | -------------------------------------------------- | ------------------------------------------ |
| Holiday Calendar | Free or from $2,500 | Guaranteed (paid) or community vote (free) | 80M+ annual visitors | Yes — email, SEO backlink, optional media pitching | Maximum discoverability and SEO |

| Days of the Year | Free | Editorial review | Global (UK-based) | No | International reach, fun/quirky holidays |
The Strategy: Which Platforms Should You Use?
You don't have to pick just one. Most successful holiday creators register on multiple platforms. The right combination depends on your budget, your timeline, and your goals.
If You're Starting From Scratch (No Existing Traction)
Skip platforms that require proven popularity. National Day Calendar's 0.15% acceptance rate and Days of the Year's preference for established holidays make them long shots at this stage.
Start with: Holiday Calendar (paid package for guaranteed listing and built-in promotion) or National Day Archives (Standard or Premium for quick guaranteed listing). Submit to Chase's Calendar as well — it's free and worth the attempt.
Then add: National Day Calendar and Days of the Year in Year 2, once you have participation data and media mentions to support your application.
If Your Holiday Already Has Traction
You have social media activity, community participation, or media coverage. Now you're stacking credibility.
Register on everything. Submit to National Day Calendar (free, and your existing traction improves your odds). Submit to Chase's Calendar (free). Apply to Days of the Year (free). Then decide whether Holiday Calendar or National Today gives you the promotional boost that best fits your audience.
If You Have Budget ($2,500–$5,000+)
Invest in platforms that do more than just list your holiday. A listing alone is a line item in a database. Promotion is what turns it into a moment.
Holiday Calendar at the $2,500 tier gives you the listing plus email promotion, SEO backlinks, and platform placement. Add their custom packages for survey data and media pitching if you want earned press coverage.
National Today at the $5,000+ level gives you access to their media and influencer network. This is the strongest option if press coverage is your primary goal.
Both are worth the investment. The question is whether you need SEO and organic discoverability (Holiday Calendar) or media and influencer distribution (National Today).
If You Have No Budget
Submit to every free platform:
- Holiday Calendar (free community submission)
- National Day Calendar (free, low odds but high reward)
- Chase's Calendar of Events (free, deadline April 15)
- Days of the Year (free, international exposure)
Then focus your energy on building traction organically. Create a hashtag. Get your community posting. Generate enough activity that the editorial platforms take notice next year.
Common Mistakes to Avoid
Registering on only one platform. Diversify. Each platform reaches a different audience. A Chase's listing reaches librarians and newspaper editors. A Holiday Calendar listing reaches millions of organic search visitors. A National Today listing reaches influencers. They're complementary, not redundant.
Confusing registration with promotion. Getting listed is step one. Getting noticed is step two. Some platforms bundle both. Others just give you a listing. Know what you're buying.
Waiting until the last minute. Chase's has a hard April 15 deadline. National Day Calendar needs six weeks minimum. Even faster platforms like Holiday Calendar recommend three to four weeks for campaigns with media pitching. Plan ahead.
Choosing a name that's already taken. Before you submit anywhere, search every platform for your proposed holiday name. Also search social media. A name collision is frustrating and avoidable.
Skipping the free platforms. Even if you invest in a paid package on one platform, submit to the free ones too. It takes 15 minutes per application and widens your footprint at no cost.
The Bottom Line
There's no single "best" platform. There's a best strategy.
The most successful branded holidays are listed on multiple platforms, each serving a different purpose. Chase's provides legacy credibility. National Day Calendar provides editorial validation. Holiday Calendar provides organic discoverability and SEO. National Today provides media amplification. National Day Archives provides speed and certainty. Days of the Year provides international reach.
Pick the platforms that match your goals. Register on the free ones regardless. Invest in the paid ones that align with your strategy.
Then do the real work: show up, promote your holiday, and give people a reason to celebrate it.
Your national day is only as real as the community you build around it. Registration is how you plant the flag. Everything after that is up to you.
