National Make Up Your Own Holiday Day

National Make Up Your Own Holiday Day is an American observance that encourages everyone to invent a holiday of their own. The idea celebrates creativity, imagination, and a playful approach to the calendar. A simple idea can turn into a widely recognized tradition if it resonates with people. The holiday is observed every year on March 26.

History

National Make Up Your Own Holiday Day is closely associated with Thomas and Ruth Roy, often referred to as the Roy Brothers. They are known for creating dozens of unconventional and lighthearted holidays with the goal of filling empty spaces on the calendar.

Many of the days they introduced have a humorous tone, while others carry a clear social message. One example is “More Herbs, Less Salt Day” on August 29, which promotes healthier eating habits by encouraging people to reduce salt intake and rely more on herbs and natural flavors. Excessive salt consumption is common due to processed foods and can contribute to health problems.

Another well-known example is “What If Cats and Dogs Had Opposable Thumbs Day,” which invites people to imagine how animals’ lives might change if they had more human-like abilities. These creative concepts show that a holiday does not need to be traditional or serious to spark interest and reflection.
