    May 17 marks the anniversary of the signing of the first International Telegraph Convention and the creation of the International Telecommunication Union.

    The long name for this day marks the merger of two nearly-identical official days in 2006 by the United Nations. One of the two days, World Telecommunication Day, was celebrated every May 17 since 1969. It marked the founding of the International Telecommunication Union on May 17, 1865.

    The second day merged into this day was World Information Society Day was also celebrated on May 17 since its inception in 2006. Its purpose was to focus on the importance of many issues in the area of information and communication technologies.



    Every year, May 17 is dedicated to World Hypertension Day (WHD).


    The purpose of the WHD:

    • To motivate the common public for regular checkup of their blood pressure at least once a year.
    • To encourage the people having hypertension on a global basis to go to their health practitioner for a regular checkup and proper treatment.
    • To promote all the common public especially youths and young people to maintain their normal weight, normal cholesterol level, normal blood pressure, healthy living, healthy eating, regular physical exercise and etc.
    • To encourage people to leave their bad habits like drinking alcohol, lazy routine, oily and fatty diet, fried and spicy diet, smoking, obese, overweight and etc.

    Hypertension is high blood pressure. The force of blood flowing through your blood vessels is consistently too high. Hypertension is sometimes called the ‘silent killer’ because it produces no symptoms and could go unnoticed and untreated for years.

    Hypertension is a public health epidemic.

    • Approximately 4 in 10 adults over age 25 have hypertension and in many countries another 1 in 5 have pre-hypertension.
    • An estimated 9/10 adults living to 80 years of age will develop hypertension.
    • One half of blood pressure related disease occurs in people with higher levels of blood pressure even within the normal range.

    These are the numbers to watch when you have had your blood pressure tested:

    • Normal: Under 120/80
    • Prehypertension: 120/80 to 139/89
    • Hypertension Stage 1: 140/90 to 159/99
    • Hypertension Stage 2: 160/100 or higher
    • Hypertension Crisis: Above 180/110


    Get your blood pressure tested. Some drug stores have do-it-yourself testing stations.
    Learn more at the International Society of Hypertension website.
    Strive to exercise more and eat better to combat hypertension.


    World Hypertension Day is an initiative of the World Hypertension League (WHL), a part of the International Society of Hypertension. WHL the day to increase the common public awareness about hypertension. The group launched the campaign of World Hypertension Day first time on May 14 in 2005 however it moved to May 17 in 2006.


    In 2017, National Day Calendar® began celebrating each state in the order they entered the union starting the week of Independence Day and ending with Hawaii. We highlight a small part of each states’ history, foods and the people who make up the state. Many states have their own state celebrations, and National Day Calendar’s observances in no way replace them. There’s so much more to explore, we can’t help but celebrate our beautiful country even more!


    On May 17th, National Idaho Day recognizes the 43rd state to join the United States union on July 3, 1890. Known by locals as The Gem State, Idaho was settled as miners, traders, and missionaries made their way West into the territory of the Nez Perce, Shoshone, and Bannock peoples.


    The state is dominated by the Rocky Mountains range. Snake River winds its way through the rugged western border of the state carving the deepest river gorge in North America. Hells Canyon National Recreation Area provides spectacular views of the dramatic landscapes the Snake River took thousands of years to sculpt.

    Idaho doesn’t lack scenery. Take any byway, and the next turn will reveal a whole new vista to observe. For example, Craters of the Moon National Monument & Preserve will seem to erupt before your eyes. This vast lava field formed from ancient volcanic activity.

    While exploring Idaho, don’t forget to investigate Hagerman’s Fossil Beds. Excavations of these well-preserved fossils have fascinated paleontologists for generations. If there is an equine interest, be sure to study the Hagerman Horse, too!

    Beyond the fossils, entire cityscapes of stone appear. The City of Rocks encountered by native peoples, pioneers, and modern-day adventurers became a kind of waystation or landmark for those who were westward bound.

    Inventors seem to like Idaho. Beyond the list of patents for improvements to printing presses and railroad technology, Idaho is the home of the television. Philo Farnsworth invented the necessary technology that brought the small screen to the mass market.

    There is a class of students annually across the country celebrating their academic achievements and accomplishments, and this National Graduation Tassel Day on May 17th is just the start. The day celebrates not only the successes but the future of every graduate!


    Each year, auditoriums and stadiums fill with proud family and friends excited to witness the commencement ceremonies of high schools, colleges, and universities. Tassels dangle from the mortarboards in the colors of their esteemed institutions. With each gown crisply pressed, graduates and families prepare for the big day.

    Graduates, as your day arrives, square your shoulders, eyes steady on the future. Pause to consider all your challenges in realizing this moment. When the principal or dean reads your name and your diploma is in hand, move your tassel.

    High school and undergraduate students start with their tassels on the right and move their tassels to the left upon graduation. For those earning graduate degrees and higher, the tassel starts on the left and moves to the right upon completion of their higher-level degrees. These traditions of moving the tassel have only recently gained popularity in the last 50 years.

    We have a certain belief the squirrels might enjoy this one. In 1958 May 17th officially recognized National Walnut Day by a Senate resolution signed into law by President Eisenhower. Today we celebrate with delicious recipes of salads, desserts, and snack foods


    Rounded, single-seeded stone fruits of the walnut tree, walnuts are a high-density source of nutrients, particularly proteins and essential fatty acids. Like other tree nuts, walnuts must be processed and stored properly.

    Grown for their seeds, the Persian or English Walnut and the Black Walnut are the two most common major species of walnuts.

    • English Walnut
      – originated in Persia
      – commercially produced
    • Black Walnut
      – native to eastern North America
      – high flavor
      – hard shell and poor hulling characteristics prevent its commercial growth for nut production.

    The husk of the walnut is peeled away from the shell at harvest. It contains juice that will readily stain anything it comes in contact with. The husk juice has been used as a cloth dye.

    The United States exports more walnuts than any other country. Ninety-nine percent of the nation’s commercial English walnuts are produced in the Sacramento and San Joaquin valleys of California.

    Baking and Cooking

    Bakers use walnuts for a variety of reasons. Walnuts add crunch and flavor to baked goods such as pies, breads, and cakes. Keep walnuts on hand to add to muffin, pancake and waffle mixes, too. But baked goods aren’t the only recipes in the kitchen where walnuts come in handy. They also get added to soups and other savory dishes. Walnuts complement fresh vegetables and salads, fruits, and more. Finely chopped walnuts create excellent crusts for fish, chicken, and pork. Don’t hesitate to explore recipes when walnuts are in season.

    HOW TO OBSERVE National Walnut Day

    Enjoy one of the following walnut recipes:

    Black Walnut Cake
    English Walnut Pie
    Pasta with Creamy Garlic & Walnut Sauce

    In June of 1949, the Walnut Marketing Board created the first National Walnut Day to promote the consumption of walnuts. Then on March 3, 1958, a Senate Resolution introduced by William F. Knowland brought an official declaration from President D. Eisenhower making National Walnut Day on May 17, 1958.



    May 17th each year dedicates the celebration of National Cherry Cobbler Day to the delicious tart dessert that many enjoy with ice cream. Many believe the early American Colonies are where this recipe began born out of a lack of proper cooking utensils.


    In the United States, cobbler refers to a variety of dishes consisting of a fruit filling (cherry being a popular choice ) covered with a batter, biscuit, or pie crust that is then baked. Some cobblers have both a top and bottom crust.

    Cobblers originated in the early British American colonies. Due to the lack of suitable ingredients and proper cooking equipment, English settlers were unable to make their traditional suet puddings. They improvised by covering a stewed filling with a layer of uncooked biscuits or dumplings.

    A cherry cobbler differs from a crisp as a cobbler lacks oatmeal. Sometimes the cobbler is topped with a scoop of vanilla ice cream, too!

    Cherries also offer a bounty of nutrients. For example, the antioxidants in this red fruit protect cells from damage. Because cherries pack an anti-inflammatory punch, they may help reduce the risk of heart disease, too.


    Bake up a delicious cherry cobbler. Make your favorite recipe or Enjoy this Cherry Cobbler recipe! Use #CherryCobblerDay to post on social media.

    Each year on May 17th, National Pack Rat Day encourages us to take a look at ourselves and see if we have “Pack Rat” tendencies within us. A Pack Rat holds on to, collects or hoards often unneeded items.


    According to Meriam Webster, the phrase pack rat dates back to 1885 and references a wood rat known for hoarding food and random objects. Today, the phrase is loosely used to describe people who do the same.

    Many people even describe themselves as pack rats because they keep things they may need in the future, such as tools, boxes, and clothing. Have you ever cleaned out a closest and critically examined every item, tossing and donating things so that you had a clean space? Then days or weeks later discovered you needed one specific item you donated or tossed. It may be a document or container, but it never fails to happen. In the age of recycling, reusing, and repurposing, pack rats consider every item before they toss and donate.

    The observance is an opportunity for the pack rat in all of us to examine our collecting tendencies. Do we really need t-shirts from 1975? When was the last time you used that L wrench that came with the pre-fabricated entertainment center you no longer own? Of course, the moment you sort through those toys and donate them, your only child will announce you’re going to be grandparents. You didn’t hold on to those pack rat tendencies long enough.


    Take a look around and maybe start cleaning out unwanted and unneeded items. If you need to, call a friend to come and help you get started. Share what you think makes you a pack rat. What do you save or collect? Use #NationalPackRatDay to post on social media.
