What is National Dimples Day?
National Dimples Day is an annual celebration of cheek and chin dimples and the people who have them. Dimples, sometimes referred to by the older term gelasin, are small natural indentations that appear most often on the cheeks when a person smiles. The day is open to everyone, whether you were born with dimples, developed them later, or simply admire them on others. Its spirit is one of self-acceptance, positivity and finding delight in the small details that make each face unique.
When is National Dimples Day?
National Dimples Day falls on Thursday, 9 July 2026. It is observed on 9 July every year, so the date never changes, only the day of the week. The founder chose midsummer deliberately, reasoning that the warmer months are when people feel most relaxed, smile most freely and are happy to show off their dimples.
The History of National Dimples Day
National Dimples Day is a relatively young celebration. It was founded in 2022 by a creator known as Graceful Grady, based in Atlanta, Georgia. The story goes that after enjoying a string of unusual and joyful holidays, he went looking for a day dedicated to dimples and was surprised to find one did not exist. Rather than let the gap remain, he decided to create the celebration himself.
Grady selected 9 July for a practical reason as much as a sentimental one. The date sat free of any major competing holidays, giving the new day room to be noticed, and it landed squarely in summer, the season he associated with joy, freedom and easy smiles. From there the day spread through social media and online holiday calendars, gathering momentum each year as people embraced its cheerful, inclusive message.
Although dimples themselves have been admired across cultures for centuries, often linked with beauty, luck and good fortune, National Dimples Day is the first occasion to give them a celebration of their own. Like many modern observances, it owes much of its reach to the internet, where a simple, positive idea can quickly find an audience. If you enjoy these joyful, internet-born celebrations, you might also like World Emoji Day, another day built around the small ways we express happiness.
Fun Facts About National Dimples Day
- Dimples are caused by a variation in the zygomaticus major muscle. In some people part of this muscle attaches to the overlying skin, creating the tell-tale infold that deepens when they smile.
- It is estimated that only around 20 to 30 per cent of the world’s population has cheek dimples, which is part of what makes them feel special.
- The genetics of dimples is more complex than once believed. Research has identified at least nine different genetic variants that can contribute to dimpling, and carrying a dimple gene makes them more likely but does not guarantee them.
- Dimples are not fixed for life. Some people are born with them and lose them with age, while others develop them later, partly because facial fat can help create the folds.
- The shape of a dimple can vary with face shape. Longer, narrower faces tend to produce longer dimples, while broader faces often produce rounder, more circular ones.
- A cosmetic procedure called dimpleplasty, which surgically creates dimples, has grown in popularity among people wanting a dimpled grin of their own.
