📅 National Mustard Day 2026

Mark your calendar  National Mustard Day 2026 lands on Saturday, August 1st. Like always, it’s celebrated on the first Saturday of August, which means the exact date shifts a little every year, but the spirit stays exactly the same: mustard, hot dogs, live music, and a whole street painted yellow.

If you’re in or near Middleton, Wisconsin, this is the day the National Mustard Museum throws its biggest party of the year, complete with food vendors, games, and thousands of mustard fans showing up just for the fun of it.

📜 National Mustard Day History

The story behind National Mustard Day actually starts with one very dedicated mustard collector. The National Mustard Museum began in 1986 when its founder and curator, Barry Levenson, started collecting mustards, eventually opening the doors to the public in Mount Horeb, Wisconsin.

The Mustard Museum began sponsoring National Mustard Day in 1991, and the celebration has kept growing ever since. The museum later moved to Middleton and took on its current name, and today it holds more than 5,600 prepared mustards from over 70 countries which is honestly more mustard than most of us knew existed.

⏳ How Many Days Until National Mustard Day

Since National Mustard Day always falls on the first Saturday of August, the countdown resets a little differently each year. For 2026, it lands on August 1st  so however many days that is from today, that’s your countdown. Set a reminder now so you’re not scrambling to find a jar of Dijon at the last minute.

🔮 National Mustard Day 2067

Because the date is tied to “the first Saturday in August” rather than a fixed number, we can’t pin down the exact calendar date for something four decades out  that depends on how the calendar falls that particular year. What we do know is that the tradition itself isn’t going anywhere. Mustard Day has run every year since 1991 without a break, so by 2067, it’ll likely be well into its seventh decade of celebration.

🏛️ National Mustard Museum

The National Mustard Museum is the heart of this entire holiday. It opened to the public in Mount Horeb, Wisconsin in 1992, originally under the name the Mount Horeb Mustard Museum, before moving to Middleton in 2009 and adopting its current name.

It’s home to a genuinely massive mustard collection, plus a gift shop, tasting counters, and enough condiment history to make you look at your kitchen shelf completely differently.
