Where the World Gathers to Celebrate Every Day


National Mario Day - March 10th


National Mario Day on Mar 10 recognizes an iconic character from a popular video game. The character, known today as Mario, first appeared in 1981 in a game called Donkey Kong made by Nintendo. 

Dedicated fans knew Mario before his time as a plumber. At his creation, Donkey Kong portrays Mario as a carpenter named Jumpman. Then in 1983, Nintendo launched a new game in which bad guy Jumpman reinvents himself into an Italian plumber who rescues princesses.

Italian plumbers, Mario and his brother Luigi face numerous obstacles in the games produced by Nintendo. Over the years, gammers help Mario cross several different landscapes all to rescue Princess Toadstool or Princess Peach, depending on which game they play. No matter the kingdom or galaxy, video game fans find the games entertaining and challenging. Many will admit, they find the characters endearing. The storylines provide hours of fun and continue to be a part of the pop culture landscape. 

Mario Fun Facts
  • Similar to Michael Michaels or Adam Adams, Mario’s last name is his first name. Luigi and Mario are known as the Mario Brothers making Mario’s last name Mario. 
  • Maybe there’s a reason National Blueberry Popover Day shares the same date. Mario pops up in all sorts of other video games.
  • With over 210 million copies of the Mario game series sold, Mario ranks as one of the most popular video games of all time.

HOW TO OBSERVE #NationalMarioDay

Whether you’re a Mario fan, a gamer, or just like to have a little fun, this day is for you. Celebrate by inviting friends and family to play. Try these ideas and share more by using #NationalMarioDay on social media:

  • Invite everyone to a video game character murder mystery night
  • Play video game trivia
  • Have a retro night and play everyone’s old favorites

Video gamers fond of the Nintendo game and its characters created the game. The date was cleverly selected for the way it spells the character’s name when abbreviated. Despite this limited information, we’ve not been able to identify specific founding members of the day. Perhaps they’re hidden in power-up or an incomplete level of the game. 



What better way to start March 10th than with National Blueberry Popover Day? Popovers are airy rolls that puff up when baked, popping over the edge of the tin. They are light and crispy on the outside while the insides are warm and often hollow. They can be filled with custards, creams, and fruits for a sweet treat, especially blueberries.   

Popovers are similar to Yorkshire pudding and can also be served with savory combinations.

Most popover recipes are made using mostly eggs, milk, flour and salt.  When making popovers, using eggs and milk that are at room temperature produces the best result. The resulting batter is thin but has enough air it that when it bakes the steam expands the batter, causing it to puff up and pop over the tin.  The egg proteins help the pastry hold its shape and eventually the crust turns flaky and golden.

** 1850 – The oldest known reference to popovers in a letter of E.E. Stuart.

** 1876 – The first cookbook with a popover recipe was Practical Cooking by M.N. Henderson.

National Pack Your Lunch Day - March 10


National Pack Your Lunch Day on March 10 encourages everyone across the country to take their lunch to work, school or where ever they’re spending the day. It’s an opportunity to revitalize lunchtime with fresh and healthful meal choices.

Packing your lunch has benefits you may not expect. One of the immediate benefits is savings. Many home-prepared lunches cost less than ordering off the take-out menu or eating out. Another benefit of making your own lunch is controlling portion sizes and ingredients. By adding fruits, vegetables, and whole grains to your lunches, they will be healthier, too. 

  • Mickey Mouse was the first licensed character to appear on a lunchbox in 1935.
  • The 1950 Hopalong Cassidy lunchbox was the first lunchbox based on a television show.

While some foods pack well for lunch, others don’t fare so well. If you’re new to packing lunches, check out this starter list:

  • Hardboiled egg – provides a serving of protein
    • peeled and placed in a separate container
  • Fresh vegetables – choose a dipping sauce like ranch or balsamic vinegar
    • carrots sticks, celery sticks, sliced cucumbers, cherry tomatoes
  • Whole fruit – apple, orange, banana, grapes, berries
  • Yogurt – provides a serving of dairy
  • Salad – prepared with deli meats of your choosing
    • place dressing in a separate container
  • Cheese
  • Crackers
  • Nuts

You will want to include a gel pack to keep your food chilled until lunchtime, even if you’re reheating leftovers.

Observed annually on March 10th, National Women and Girls HIV/AIDS Awareness Day empowers people everywhere with knowledge and information regarding HIV/AIDS. It also focuses on the often overlooked impact it has on women and girls.

According to the CDC, HIV diagnoses in women are down 21%. However, in 2017, over 7,000 new cases were reported. When it comes to HIV, abstinence is the only way to prevent HIV. Other important facts to know:

  • Condom use reduces the risk of infection. Use a new condom every time you have sex.
  • Testing is the only way to know for sure if you have HIV
  • Pre-exposure prophylaxis (PrEP) offers hope for couples in relationships where one partner has HIV and the other doesn’t. Speak to your doctor about taking daily PrEP.
  • Don’t put off medical care. Even if you already know your HIV status, putting off needed care may compromise your health in unnecessary ways. If you or someone you know isn’t seeking help out of fear of violence or rejection please call the Domestic Violence Hotline at 1-800-799-SAFE (7233).
  • Medicine has come a long way baby. If you’re pregnant with HIV, the risk of passing it to your baby is less than .1% but it’s important that you work with a healthcare professional. Don’t wait. 
  • HIV is spread through sharing needles, syringes or other equipment. Never share needs. It increases your risk of infections.
  • Do you live with HIV? Take your medication as prescribed daily. It reduces your viral load and lowers the chance of transmitting HIV during sex to an HIV-negative partner.


Throughout the country, supporters will change their social media profiles reflecting their support for friends and family members with HIV/AIDS. Clinics will host testing sights, encouraging women to test. Others will be inviting pregnant women to come in for exams. Other ways to participate include:

  • Visit womenshealth.gov to learn more about preventing HIV/AIDS.
  • Encourage more women and girls to get tested.
  • Provide services to those living with the disease.
  • Talk to our daughters about the disease and how to protect themselves.
