On July 24th, commemorate National Tequila Day with a little lime and salt. Mix up a Margarita, Paloma, or a Mamasita to celebrate the day! People have been making Tequila for centuries, and it was once known as mezcal wine.

In fact, Tequila is mezcal, but mezcal isn’t Tequila. That’s because Tequila is distilled from a specific type of agave plant. Also, the law protects its production. Take a sip, and we’ll travel into Tequila’s history.

Tequila History

It all started around the 16th century. Cortez arrived on the North American continent with his Spanish conquistadors. They didn’t care much for the fermented mezcal wine served to them. However, the Spanish introduced copper stills to the population. Enter the distilling process. 

Now, our story takes us to Tequila, Jalisco, Mexico. Located in a valley west of Guadalajara in Jalisco, Mexico, the town made a name for themselves by distilling Blue Agave. Even though a variety of succulents in Mexico produce mezcal, only one delivers the nectar to distill Tequila. Blue Agave grows in the highland region. Indeed, the unique growing conditions contribute to a larger size and sweeter tasting agave. In contrast, agave grown in the lowland regions taste and smell more herbal.

In Mexico, the law protects the production of Tequila. The rule states Tequila is only Tequila if it is made within Jalisco. Additionally, the law limits production to regions in the states of Guanajuato, Michoacan, Nayarit, and Tamaulipas. However, the same ingredients distilled anywhere else cannot be labeled Tequila. 

Interestingly, many names in the tequila business today were the very first commercial producers of Tequila. For example, José Antonio Cuervo held the first license for making the favored beverage. He kept a well-known company, too. Two other names include Don Cenobio Sauza and Félix López, whose businesses continue in some form today.

Equally enjoyed in cocktails such as the margarita or tequila sunrise, connoisseurs savor a good tequila like a good whiskey. As a result, savvy drinkers experience the smooth renaissance of Tequila. Surprisingly, it’s not the firewater they remember from their youth. 

HOW TO OBSERVE #NationalTequilaDay

While cooking up fajitas, mix a drink for you and your friends. Try margaritas or a new cocktail. Make a celebration out of your meal.  (Remember always to drink responsibly and never drink and drive). Join the conversation by posting on social media using #NationalTequilaDay.


National Day Calendar is researching the origins of this beverage holiday.NATIONAL THERMAL ENGINEER DAY – July 24


Thermally speaking, July 24th is an excellent day to acknowledge National Thermal Engineer Day. Since it is one of the hottest days of the year, celebrate the contributions of thermal engineers.

Electronics thermal management is pivotal for its longevity and reliable operations. Yet thermal engineers who make this possible receive little to no recognition. The market sector doesn’t matter, either. They may work in consumer electronics, large data centers, or cutting-edge biomedical or aerospace electronics. Either way, they contribute to the cornerstone of our nation’s technological advancement. Without thermal engineers, modern life doesn’t function. 

As specially trained professionals, thermal engineers develop solutions to complex systems. At the same time, their focus may be on the mechanical, but thermal engineers also coordinate with other specialties. By combining communication and organizational skills, these specialists ensure operations continue to run smoothly. On a project, these skills bring a project to an economical and timely resolution. Their efforts create more efficient and innovative infrastructure. The results of their efforts are all around us every day.

Of course, thermal engineers understand and work with heat management. That’s what they do. They certainly don’t sweat the small stuff. So, it only fits to recognize them on one of the hottest days of the year – July 24th. 

HOW TO OBSERVE #ThermalEngineerDay

While you’re celebrating the day, buy a thermal engineer an ice-cold drink. Thank them for their work, too. If you’re interested in a career, learn more about thermal engineering. Post on social media using #ThermalEngineerDay to encourage others to join the conversation.


In July of 2014, Advanced Thermal Solutions, Inc. (ATS) founded National Thermal Engineer Day to recognize the innovation and commitment of the motivated and dedicated electronics and engineering industry. Advanced Thermal Solutions, Inc. (ATS) firmly believes in the importance of advancing the thermal engineering industry and is committed to providing the electronics industry with innovative, high-quality, and cost-effective thermal management and electronics packaging solutions.

The Registrar at National Day Calendar proclaimed in 2014 National Thermal Engineer Day to be observed July 24th annually.



National Cousins Day on July 24th recognizes the lifelong relationships that grow among cousins. Our first friendships often form with cousins as young as infants and endure a lifetime. 

Whether cousins grow up together in close-knit families or only see each other occasionally, they share common memories through grandparents, aunts, and uncles. At family gatherings, cousins entertain each other and get into trouble together, too. They celebrate birthdays and might even blow out the other’s candles to their cousin’s annoyance. When their siblings irritate them, cousins become an ally. Sometimes cousins seem more like siblings, especially if they’re only children.

As cousins grow up, watching their children grow reminds them of their youth. And that’s when the cycle begins anew.

The day celebrates every age of cousins – new baby cousins and cousins whose babies are all grown up!

HOW TO OBSERVE #NationalCousinsDay

Gather up your cousins and take a photo. Send a text to your cousins who are too far away. If you need to hear their voices, give them a call. Reminisce over the good times. Be sure to laugh about those things that didn’t seem so funny at the time. Post photos on social media using #NationalCousinsDay.


While National Day Calendar continues researching the origins of this family-themed day, check out these other popular celebrations:

    National Day of the Cowboy on the fourth Saturday in July recognizes the stoic, hardworking symbol of the American West. 

    The era of the cowboy began after the Civil War in the heart of Texas. Cattle were herded long before this time, but in Texas, they grew wild and unchecked. As the country expanded, the demand for beef in the northern territories and states increased. With nearly 5 million head of cattle, cowboys moved the herds on long drives to where the profits were.

    The draw of riches and adventure mixed with tales of violence. Among the grand backdrop of the Great Plains, the mythological image of the cowboy emerged. 

    Where the dust settles reveals much of the stoic truth of the American cowboy and cowgirl. The life of a cowboy required a particular ability to live in a frontier world. To do so requires respect, loyalty, and a willingness to work hard.

    In the words of former President George W. Bush, “We celebrate the Cowboy as a symbol of the grand history of the American West. The Cowboy’s love of the land and love of the country are examples for all Americans.”

    HOW TO OBSERVE #NationalDayOfTheCowboy

    Celebrate with a cowboy you know and post on social media using #NationalDayOfTheCowboy.  Enjoy a western novel or movie, attend a rodeo, and embrace the cowboy way of life.


    According to the National Day of the Cowboy Organization, this day “…is a day set aside to celebrate the contributions of the Cowboy and Cowgirl to America’s culture and heritage.” The NDOC continuously pursues national recognition of National Day of the Cowboy. Currently, 14 states recognize this day. The first celebration was in 2005. 



    National Drive-Thru Day on July 24th recognizes an innovation conveniently going strong today. The drive-thru reached its iconic zenith in the 1950s but stayed strong through the 60s, 70s and beyond. People have enjoyed this service since the 1930s.

    The ease of dropping off or picking up an item without getting out of the car may be something we take for granted. Of course, many studies point to the benefits and drawbacks associated with using the drive-thru.

    The first and most obvious that comes to mind is the ease of dropping off or picking up and item. Whether its the mail, a prescription or the dry cleaning, pulling up to a window or a slot and passing the article through is eminently easier than even finding a parking spot. Then, if we have children, we collect our children, our item and wait in line. After waiting, we usually search for our parking spot while juggling children and once again pile them back into the car. When multiple stops are involved, repeat the previous steps. Check the ease of use box.

    Secondly, many people think the drive-thru is faster. While that might be true at some locations, it will depend on the type of service, time of day, and where you are located. For example, a long line in the drive-thru at the bank may mean no waiting inside. The same may also be true at your favorite fast-food restaurant. However, if you only need to drop off a letter at the post office, use the drive-up option.

    Finally, accuracy tops the list of some drive-thru specialists. Again, this criteria is hit or miss. Depending on the type of business, time of day and location, accuracy varies. Interestingly, in 2018, Chic-fil-A mastered this arena with 97.3% accuracy.

    Did you know:
    • There are more than 211,000 fast-food restaurants in the United States.
    • The drive-thru format was pioneered in the United States for banking services.
    • Hamburgers sold for just 18 cents at some of the first drive-thru restaurants.
    • Restaurants, coffee shops, liquor stores, pharmacies, and many more services utilize drive-thrus for quick service.

    HOW TO OBSERVE #NationalDriveThruDay

    Enjoy the day by uses all the drive-thrus available to you. Post on social media using #NationalDriveThruDay to encourage others to celebrate the day with you.


    America’s first drive-thru burger chain, Jack in the Box, created National Drive-Thru Day to celebrate America’s love of convenience by car.



    Each year on July 24th, National Amelia Earhart Day honors the achievements of the aviation pioneer on the date of her birth. 

    Author and American aviation pioneer, Amelia Mary Earhart was born on July 24, 1897. One of Earhart’s most impressive achievements took place on May 20th, 1932. In 1927, Charles Lindbergh completed the first solo flight across the Atlantic. He flew from New York to Paris in 33 hours and 30 minutes. 

    Earhart took off from Grace Harbor, Newfoundland four years to the day Lindbergh completed his flight. Throughout the flight, she faced many technical difficulties. Her goal was to land in Paris, France. The previous year, Ruth Nichols also attempted to fly solo across the Atlantic. Had she succeed, she would have been the first woman to do so. However, Nichols’ crashed while attempting to land for refueling in New Brunswick, Nova Scotia.

    Due to Earhart’s challenges in flight, she landed the red Lockheed Vega 14 hours and 16 minutes later in Derry, Ireland. All in all, the flight was a success. She became the first woman pilot to complete the journey. Following Earhart’s record-setting accomplishment, she earned the United States Distinguished Flying Cross.

    More Earhart Facts
    • Broke many other records
    • Wrote best-selling books about her flying experiences
    • Instrumental in the formation of The Ninety-Nines (an organization for female pilots)
    • Joined the Purdue University aviation department faculty in 1935 as a visiting faculty member to counsel women on careers and help to inspire others with her love for aviation.
    • Member of the National Woman’s Party
    • Supporter of the Equal Rights Amendment

    In 1937, Earhart attempted to circumnavigate the globe. Unfortunately, her Purdue-funded Lockheed Model 10 Electra disappeared over the Pacific Ocean near Howland Island in July. 

    Today, her successes continue to draw women around the globe to the world of aviation. Fascination with her life, career, and disappearance continues to this day. Whether or not the mystery will ever be solved remains to be seen.
