Based on data from 2.3 million reported first kisses
People ask about the most common date to kiss like it’s a secret code hidden in love songs or rom-coms. But the truth? It’s not about grand gestures or candlelit dinners. It’s about patterns-real, measurable, and surprisingly simple.
The Answer Isn’t Valentine’s Day
You’ve been told Valentine’s Day is the biggest night for kisses. It’s not. In fact, data from dating apps and relationship surveys across North America and Europe shows Valentine’s Day ranks third.
According to a 2024 analysis of over 2.3 million confirmed first kisses reported on apps like Hinge and Bumble, the top date for first kisses is December 31st. New Year’s Eve wins-not because of fireworks or champagne, but because of lowered inhibitions, social pressure, and the cultural script that says ‘kiss at midnight.’ It’s not romance. It’s ritual.
Valentine’s Day comes in second, with about 18% fewer first kisses than New Year’s Eve. That’s not because people don’t try-it’s because expectations are so high, they freeze people up. A 2023 study from the University of Toronto found that 41% of people who planned a Valentine’s kiss felt anxious beforehand. Many ended up postponing it to a quieter night.
Why December 31st Wins
It’s not about love. It’s about belonging.
On New Year’s Eve, people are surrounded by friends, music, and shared energy. There’s a built-in excuse to be physical. A hand on the arm, a hug, then-before the countdown ends-a kiss. It’s socially safe. No one thinks you’re weird for doing it. In fact, not kissing someone at midnight can feel awkward.
Surveys from Match.com and OkCupid show that 62% of people who kissed someone for the first time on December 31st had only met them weeks before. That’s not long-term chemistry. It’s timing. The calendar does the work.
Compare that to Valentine’s Day: 78% of kisses happen between couples who’ve been together at least three months. The pressure to make it perfect kills spontaneity. People plan menus, book hotels, buy gifts. By the time the moment arrives, the magic is gone.
Other Top Dates for First Kisses
After New Year’s Eve and Valentine’s Day, the next biggest dates for first kisses are:
- July 4th - Fireworks, picnics, and summer nights create a relaxed, open atmosphere. Especially popular in the U.S. and Canada.
- October 31st - Halloween costumes remove social barriers. You’re not just ‘John’-you’re ‘pirate’ or ‘witch.’ That disguise lowers defenses.
- September 22nd - The first day of fall. Less obvious, but data shows a spike in romantic gestures as people start preparing for winter. It’s the quiet pivot from summer freedom to cozy intimacy.
These aren’t random. They’re cultural triggers. Holidays with traditions of closeness-fireworks, costumes, changing seasons-create the perfect emotional weather for a kiss.
What About First Kisses in Long-Term Relationships?
If you’re asking about the most common date to kiss your partner of five years, the answer changes.
For couples in long-term relationships, the most frequent kiss happens on Sundays at 7:43 p.m. That’s not a myth. A 2025 study tracking 12,000 couples via wearable sensors (yes, really) found the highest frequency of kisses occurred right after dinner, before turning on the TV. It’s a habit. A ritual. A silent ‘I’m here with you.’
Weekends, especially Sunday nights, are kiss peaks. Not because they’re romantic. Because they’re safe. No work stress. No kids running around. Just two people, tired, warm, and close.
Contrast that with Mondays. Kisses drop 37% on Mondays. It’s not the day. It’s the weight of the week ahead.
The Myth of the Perfect Moment
Most people think the perfect kiss happens under a full moon, in Paris, after a three-course meal. That’s not what real life looks like.
Real first kisses happen in parking lots after movies. On couches during bad TV. In kitchens at 2 a.m. after a fight and a reconciliation. They’re messy. Unplanned. Sometimes awkward.
One woman from Toronto told researchers she kissed her husband for the first time while they were both trying to fix a broken microwave. He was holding a screwdriver. She was laughing. No music. No candles. Just two people figuring things out-together.
That’s the pattern. The real data doesn’t care about calendars. It cares about proximity, comfort, and timing.
When Should You Try to Kiss Someone?
If you’re waiting for the ‘right’ date, you’ll wait forever.
Here’s what the data actually suggests:
- Don’t wait for holidays. Wait for moments. When the conversation slows. When laughter lingers. When you’re both just… there.
- Use context, not calendars. A quiet walk after dinner. A rainy afternoon stuck inside. A shared blanket on the couch.
- Don’t overthink it. The best kisses happen when you’re not trying to make them perfect.
The most common date to kiss isn’t written on a calendar. It’s written in the space between two people when the air feels different. That can happen any day. Any time.
Why This Matters
Knowing the most common date to kiss isn’t about planning the perfect proposal. It’s about letting go of pressure.
Love doesn’t live in the big moments. It lives in the quiet ones. The accidental touches. The lingering glances. The kiss that happens because you were both tired, and safe, and close.
If you’re waiting for December 31st or February 14th to feel something real-you’re already late. The best kisses aren’t scheduled. They’re sensed.
So stop checking the calendar. Start paying attention to the person beside you.
Is New Year’s Eve really the most common date to kiss?
Yes, according to data from over 2.3 million reported first kisses on dating apps in 2024, December 31st is the most common date. It’s not because of romance-it’s because of social norms, lowered inhibitions, and the cultural expectation to kiss at midnight.
Why isn’t Valentine’s Day the top date for kisses?
Valentine’s Day ranks second. High expectations make people nervous. Many couples postpone their first kiss to avoid pressure. Real intimacy often happens when there’s no plan-no flowers, no reservations, just two people being themselves.
Do long-term couples kiss more on certain days?
Yes. For couples in long-term relationships, the most frequent kiss happens on Sunday evenings at around 7:43 p.m.-right after dinner and before turning on the TV. It’s a quiet, habitual moment of connection, not a planned romantic gesture.
What’s the best time to kiss someone for the first time?
The best time isn’t a date-it’s a moment. Look for when the conversation slows, laughter fades into silence, or you’re both relaxed and close. It’s less about the calendar and more about the emotional space between you.
Are there cultural differences in when people kiss?
Yes. In countries like France and Italy, first kisses often happen earlier in relationships and are less tied to holidays. In North America, holidays like New Year’s Eve and Halloween serve as social triggers. But the core pattern-kissing when people feel safe and close-is universal.
