You're looking at your calendar. Maybe you're planning a long weekend or just wondering why your inbox feels a little quieter today. March 24 isn't exactly Christmas or the Fourth of July, so it doesn't always get the big "bank holiday" treatment in the United States. But honestly, if you live in Argentina or care about global human rights, this date is massive.
It’s a weird day.
For some, it’s a somber reminder of political upheaval. For others, it’s about a specific saint or even just a quirky food celebration. If you’re asking what holiday is March 24, the answer depends entirely on where you’re standing and what you value.
The Heavy Hitter: Argentina’s Day of Remembrance
In Argentina, March 24 is a national public holiday. It’s officially called the Día Nacional de la Memoria por la Verdad y la Justicia (National Day of Remembrance for Truth and Justice). This isn't a day for barbecues and beach trips, even though businesses close down. It’s heavy.
Back in 1976, a military coup overthrew Isabel Perón. What followed was a dark era known as the "Dirty War." Thousands of people—students, activists, journalists—simply disappeared. They became los desaparecidos.
Decades later, in 2002, the Argentine government finally made this an official day to reflect on those human rights abuses. You'll see massive marches in the Plaza de Mayo in Buenos Aires. People carry banners with the faces of the missing. It’s a gut-wrenching, powerful display of "Never Again" (Nunca Más). If you are doing business with South American partners, don't expect them to answer the phone on this day. They are remembering.

A Global Stand for Human Rights
The United Nations also circles this date on the calendar. They call it the International Day for the Right to the Truth Concerning Gross Human Rights Violations and for the Dignity of Victims.
That’s a mouthful.
Basically, the UN wants to honor Monsignor Óscar Arnulfo Romero. He was a priest in El Salvador who spoke out against poverty and social injustice. On March 24, 1980, he was assassinated while celebrating Mass. It was a shock to the world.
The UN chose this date to recognize his sacrifice and to remind every country that victims of violence have a right to know the truth. Who did it? Why? Where are the bodies? It’s about accountability. In a world where misinformation spreads like wildfire, the "Right to the Truth" feels more relevant than ever.
Religious Observances: St. Oscar Romero and Gabriel
For the religious folks, March 24 carries specific weight in the liturgical calendar.
- Saint Oscar Romero: As mentioned, he’s a huge figure in the Catholic Church, especially after being canonized by Pope Francis in 2018.
- Archangel Gabriel: Historically, in some older Christian traditions, March 24 was the Eve of the Annunciation. Before the calendar shifted around in various reforms, this was sometimes celebrated as the feast of the Archangel Gabriel—the messenger who told Mary she’d be having a baby.
While most people just wait for Easter in the spring, these smaller feast days provide a rhythm to the month for millions of practitioners globally.
The Quirky Side: National Chocolate Covered Raisin Day
Okay, let’s pivot. Hard.
If you aren't protesting in Argentina or attending a solemn Mass, you might be at the grocery store buying snacks. In the U.S., March 24 is National Chocolate Covered Raisin Day.
Is it a "real" holiday? No. You still have to go to work. But the candy industry loves it.
Raisins coated in chocolate date back to the early 20th century. The most famous brand, Raisinets, was introduced in 1927 by the Blumenthal Chocolate Company. Eventually, Nestlé took them over (and later sold them to Ferrero). There’s something strangely nostalgic about them. They’re the "healthy" candy—or at least that's what we tell ourselves because there's fruit inside.
If you want to celebrate, just grab a box at the cinema. It’s low-stakes. It’s easy. It’s a nice break from the heavier historical context of the day.
World Tuberculosis (TB) Day
On the health front, March 24 is a critical day for doctors and researchers. It’s World TB Day.
Why this day?
On March 24, 1882, Dr. Robert Koch announced that he’d discovered the bacterium that causes tuberculosis. At the time, TB was killing one out of every seven people living in the U.S. and Europe. Koch’s discovery was the "Eureka!" moment that paved the way for a cure.
Even though we often think of TB as a "Victorian" disease, it’s still one of the world’s deadliest infectious killers. Organizations like the CDC and the WHO use this day to raise money and awareness. They usually pick a theme, like "Yes! We can end TB!" It’s a reminder that global health requires constant vigilance.

What Should You Actually Do on March 24?
So, you know what holiday is March 24 now. What’s the move?
If you’re a history buff, spend some time reading about the "Madres de Plaza de Mayo" in Argentina. Their resilience is staggering. They wore white headscarves to represent the diapers of their missing children and marched when it was dangerous to do so.
If you’re a bit burnt out, honestly, just lean into the chocolate-covered raisins. We all need a win.
For the activists, check in on global human rights reports. The "Right to Truth" isn't just about the 1970s; it’s about transparency in modern governance.
Actionable Steps for the Date
- Check Local Closures: if you are in Argentina, everything is shut. If you're in the U.S. or UK, it’s business as usual.
- Health Screening: If you’ve been coughing or traveling in high-risk areas, use World TB Day as a reminder to get a check-up.
- Support a Cause: Consider donating to organizations like Amnesty International or the Romero Trust.
- Snack Strategically: Buy the Raisinets. You know you want to.
The beauty of March 24 is its duality. It’s a day of deep, painful remembrance for some and a day of scientific triumph or simple sweetness for others. It reminds us that every single day on the calendar is layered with centuries of human experience, from the death of a Queen to the discovery of a germ. Enjoy the spring air, acknowledge the history, and maybe eat some chocolate.
The best way to respect the day is to be aware of the "Truth" the UN talks about—knowing the story behind the date makes the date itself more meaningful.
Check your specific region's community calendar for local marches or health clinics, especially in urban centers where World TB Day events are most common. If you are a teacher or parent, this is a prime opportunity to discuss the concept of "disappeared" history versus "documented" history with students, using Argentina as a primary case study. It’s a lesson in how silence can be a political tool and how memory is a form of resistance. Regardless of how you spend the hours, March 24 serves as a bridge between the cold of winter and the full bloom of April, carrying the weight of the past into the possibilities of the future.
