You’re standing there, mistletoe or not, wondering if today is actually the day you’re supposed to pucker up. It’s a valid question. Honestly, the internet has made a complete mess of the calendar when it comes to "National Kiss Day" versus "International Kissing Day." You’ll see one person posting a selfie on June 22nd and another person waiting until July 6th.
It’s confusing.
The short answer? If you are looking for when is National Kiss Day, the date most people in the United States recognize is June 22. However, if you miss that window, you’ve got a backup on July 6. The difference boils down to geography and who started the "holiday" in the first place.
Why the Date for National Kissing Day Keeps Shifting
Dates get messy. Back in the early 2000s, various "National Day" calendars began popping up online, and June 22 somehow became the designated spot for the U.S. version. It isn't a federal holiday—you won't get the day off work, unfortunately—but it’s become a massive social media fixture.
Then there is the UK influence.
Across the pond, the United Kingdom established National Kissing Day decades ago, eventually pushing it to become an international event. They settled on July 6. Because the internet doesn't have borders, these two dates often bleed into one another. You’ll see brands running campaigns in June and then influencers doing the same thing two weeks later. It's basically a month-long celebration of physical affection if you play your cards right.
Why do we even have these days? It sounds a bit cheesy, sure. But organizations like the British Dental Health Foundation have historically leaned into these dates to talk about oral hygiene. It's not just about romance; it's about the weirdly complex biological exchange that happens when two people lock lips.
The Science Most People Ignore on June 22
A kiss isn't just a kiss. When you celebrate when is National Kiss Day, you’re actually participating in a massive chemical hit to your brain.
Think about the last time you had a really great first kiss. Your heart races. Your pupils dilate. This isn't just "the vibes." It’s a cocktail of dopamine, oxytocin, and serotonin. Anthropologists like Helen Fisher have spent years studying this. She argues that kissing is an evolutionary tool used to assess a mate. We are literally sniffing out each other's genetic compatibility.
"Kissing is a mechanism for mate choice," Fisher has noted in various lectures. It’s a sensory audition.

But it’s also a health thing. Believe it or not, a passionate kiss can burn about two to three calories per minute. It’s not exactly a HIIT workout at the gym, but it beats sitting on the couch. More importantly, frequent kissing has been linked to lower levels of cortisol—the stress hormone that makes us feel like we’re constantly vibrating with anxiety.
The Cultural Divide: Is it June 22 or July 6?
If you want to be technically correct (which is the best kind of correct), here is the breakdown:
- June 22: This is the "National" version, primarily used by Americans.
- July 6: This is "International Kissing Day." It started in the UK and has the most global traction.
Sometimes you'll even see February 14th thrown into the mix, but that's just Valentine's Day overshadowing everything. There’s also "Kiss Your Crush Day" on October 19th, which feels a bit more high-school-dance-energy than the June or July celebrations.
Famous Kisses That Changed the World
We can't talk about a day dedicated to kissing without mentioning the imagery that defined it. You know the one. The sailor and the nurse in Times Square? That photo, taken by Alfred Eisenstaedt on August 14, 1945, is arguably the most famous kiss in history.
But it’s also controversial.
In recent years, historians and the public have looked closer at that photo. Greta Zimmer Friedman, the woman in the photo, later revealed that she didn't know the sailor, George Mendonsa. It wasn't a romantic moment; it was a spontaneous, somewhat aggressive outburst of celebration at the end of World War II. It’s a reminder that context matters—even on a day meant for affection.
Then you have the cinematic greats. Lady and the Tramp and that single strand of spaghetti. The upside-down rain kiss in Spider-Man. These moments cement the holiday in our collective consciousness. They make us want to know when is National Kiss Day because we want a piece of that cinematic magic in our own mundane Tuesdays.
The Health Benefits You Didn't Ask For
Let's get clinical for a second. Your mouth is a biological disaster zone. There are roughly 700 species of bacteria living in there. When you kiss someone for 10 seconds, you transfer about 80 million bacteria.
Gross? Maybe.

Beneficial? Actually, yes.
A study published in the journal Microbiome found that this exchange of bacteria can actually help prime the immune system. It’s like a tiny, wet vaccination. By exposing yourself to your partner's oral flora, your body builds up defenses. It’s weirdly beautiful in a "don't think about it too hard" kind of way.
Beyond the germs, there’s the "vagus nerve" stimulation. This nerve runs from your brain to your heart and stomach. Deep kissing stimulates it, leading to a state of relaxation. This is why a good kiss can feel like a "reset" button after a long day of staring at spreadsheets and dealing with traffic.
How to Celebrate Without Being Weird
Look, "National Kiss Day" doesn't mean you should go around bothering strangers. That’s a fast track to a HR meeting or a police report.
The best way to observe the day is to focus on the people you already care about. It doesn't even have to be romantic. In many cultures—think France, Italy, or Spain—the "air kiss" or the cheek kiss is a standard greeting. It’s about connection.
If you’re planning to mark June 22 on your calendar, here are some ways to do it right:
- Check your breath. It sounds basic, but if you’re celebrating a day about mouths, maybe skip the extra onions at lunch.
- The "Check-In." If you're with a partner, use the day to actually be present. Life gets busy. We forget to stop and actually look at the person we live with.
- Skincare matters. Chapped lips are the enemy of a good National Kiss Day. Grab some lip balm.
Why We Still Care About These "Made-Up" Holidays
You might think National Kiss Day is just a creation of Big Greeting Card or a way for Instagram to stay busy. You’re not entirely wrong. Many of these days are pushed by marketing firms to drive engagement.
However, they persist because humans are social creatures. We like excuses to celebrate. In a world that feels increasingly digital and distant, a day that celebrates the most basic form of human touch actually serves a purpose. It’s a reminder that we aren't just avatars on a screen.
Whether you choose the June date or the July date, the sentiment remains. It’s about breaking down the walls we build up during the work week. It’s about a moment of vulnerability.

Actionable Steps for National Kissing Day
Since you now know when is National Kiss Day (June 22!), you can actually prepare for it instead of being blindsided by a trending hashtag.

The mystery of the date is solved. June 22 is your target. Keep the July 6 date in your back pocket as a "Part Two." Now, go buy some mints and make sure your lip balm hasn't expired.
