    Every year on March 21st, International Colour Day celebrates all aspects of colour and the impact it has on our lives. The day also encourages people to think about how colour makes our world a better place.

    Colour has played an integral role in our world from practically the beginning of time. For centuries, people have experimented with different pigments for writing, drawing, and expressing themselves. One of the oldest known pigments is red ochre. This pigment was found in a prehistoric cave painting. Iron-rich soil helped to create the pigment. As far back as 40,000 years ago, artists used animal fat, burnt charcoal, and chalk to create different pigments of color. Along with red, other pigments that were created during this time were brown, yellow, black, and white.

    Since that time, people have been able to create millions of different colors. According to some scientists, humans are capable of seeing 10 million different colours. Some people believe there are far more colours than that, however. This is because of the different shades of light that affect colour. One colour expert believes there are actually 18 decillion colours. If you are not sure how many that is, it is the number 18 followed by 33 zeroes. That is a lot of colours for our viewing enjoyment!

    Colours & Emotion

    Not only are colours beautiful to look at, but certain colours evoke different emotions.

    • Red: excitement, love, and energy
    • Orange: confidence, bravery, and success
    • Yellow: creativity, happiness, and warmth
    • Green: healing, freshness, and tranquility
    • Blue: trust, peace, and loyalty
    • Pink: compassion, sincerity, and sweetness
    • Purple: royalty, ambitious, and luxurious
    • Brown: trustworthy, dependable, and simple
    • Black: formal, dramatic, and sophisticated
    • White: clean, innocent, and honest

    Are any of these colours your favorite? What are some emotions that you associate with certain colours?

    HOW TO OBSERVE #InternationalColourDay

    On this day, a variety of events are held throughout the world. Some of these events include art exhibitions, design contests, and workshops on the use of colour and light.

    To participate:

    • Make a colour wheel with your children. Teach them about the primary colours and complementary colours.
    • Have a contest with your friends to see who can come up with the most colors.
    • Visit an art museum and pay close attention to the different colours in the paintings.

    The Portuguese Color Association proposed an International Colour Day in 2008. In 2009, the International Colour Association agreed to the proposal. They decided on the date March 21st because it is the equinox. During the equinox, night and day are almost equally long. This is symbolic of the association of light and darkness, which is expressed in all human cultures.




    Every year on March 21st, World Puppetry Day seeks to recognize puppetry as a global art form. It’s also a day to honor puppeteers around the world.

    You are probably familiar with puppets. If you’re like most people, you have probably seen a puppeteer in action. You may have even played with a puppet yourself. You may be surprised to discover, however, just how old the art of puppetry is. Puppets date all the way back to the 5th century BCE. China, India, and other places in Asia even had puppet theaters. Native Americans also used puppet-like figures in certain rituals.

    In 1929, the Union Internationale de la Marionnette – International Puppetry Association (UNIMA) was created in Prague. In the United States, puppeteers kept their art a secret. It wasn’t until the first half of the 20th century that puppeteers began sharing more information about their work. They also began holding public puppet shows. This was largely thanks to Tony Sarg, a famous puppeteer at that time. When puppets became public, it led to the founding of the Puppeteers of American in 1937. In 1966, Jim Henson founded UNIMA-USA. UNIMA Australia, UMIMA Pakistan, British UNIMA, and UNIMA-France followed suit.

    Today, puppets are everywhere. Not just in the United States, but around the world. Puppets can be seen on stage, on television, and in the movies.
    Some of the most famous puppets include:

    • Pinocchio
    • Punch and Judy
    • Howdy Doody
    • Lamb Chop
    • Kermit the Frog
    • Elmo
    • Daniel Striped Tiger

    Can you think of a famous puppet that you grew up watching on television or saw in the movies?

    HOW TO OBSERVE #WorldPuppetryDay

    The most popular events on this day are, of course, puppet shows!

    To participate:

    • Help your children make their own puppets.
    • Gather your toy puppets together and put on a puppet show of your own.
    • Learn about famous puppeteers like Fred Rogers, Jim Henson, Bil Baird, Shari Lewis, and Frank Oz.
    • Watch TV shows and movies featuring puppets including The Muppets, Sesame Street, Mr. Rogers Neighborhood, and Alf.

    Don’t forget to share your favorite puppet on social media with #WorldPuppetryDay.


    Puppet theater artist, Javad Zolfaghari from Iran, came up with the idea for World Puppetry Day. He proposed a discussion for the day in the year 2000 during the UNIMA World Congress. In 2002 UNIMA declared March 21st as World Puppetry Day. The first official World Puppetry Day was held on March 21st, 2003.




    Each year on March 21st, the International Day of Forests celebrates and raises awareness of the importance of all types of forests.

    Forests cover one-third of the Earth’s landmass. Around 1.6 billion people depend on forests for their livelihood, medicines, fuel, food, and shelter. Forests are also home to more than 80 percent of land animals, insects, and plants. There are 3 trillion trees in all the forests on Earth. Forests are defined as a large group of trees. In order to be considered an actual forest, trees have to cover at least 0.5 hectares.

    The three primary types of forests include:

    • Tropical: temperatures range from 68 to 77 degrees F. and receives 100 inches of rain a year
    • Temperate: broken down into two subcategories including temperate deciduous and temperate coniferous
      • Found in China, Japan, and the Eastern United States and Canada, temperate deciduous forests receive between 30 to 60 inches of rain a year.
      • Look for temperate coniferous forests in New Zealand, South America, and Pacific Northwestern United States and Canada. They receive between 50 and 200 inches of rain a year.
    • Boreal: Also known as Taiga forests, they grow in cold climates, such as Siberia, Canada, and Scandinavia. They receive between 15 and 40 inches of precipitation a year.

    All forests contribute to the Earth’s ability to maintain its climate. Forests also help prevent soil erosion and act as water filters. Besides providing food and raw materials, forests promotes ecotourism and help make our planet look more beautiful.

    HOW TO OBSERVE #InternationalDayOfForests

    Countries are encouraged to organize activities, such as tree-planting campaigns. Other events held on this day include art exhibitions, photo competitions, student debates, and symposiums.

    To participate:

    • Think about the crucial role our earth’s forests play in climate change.
    • Teach your kids how to identify different trees or teach them about animals that live in the forest.
    • Visit a public forest or nearby National Park.
    • Watch a documentary about forest preservation, like If a Tree Falls, The Burning Season, or The Forgotten District.
    • Take part in a tree-planting event.

    Spread awareness for this day on social media with #InternationalDayOfForests


    In November 1971, during the Conference of the Food and Agriculture Organization, member states voted to establish World Forestry Day to be held on March 21st of each year. From 2007 to 2012, the Center for International Forestry Research convened a series of six Forest Days. These days were held in conjunction with annual meetings on climate change. On November 28, 2012, the United Nations General Assembly established the International Day of Forests. The first event was held on March 21st, 2013.

    Recent themes have included:

    2020: Forests and Biodiversity

  • NATIONAL 3-D DAY – 3rd Day of 3rd Week in March


    National 3-D Day celebrates the art, science, and history of stereoscopic 3-D imagery. Every year, in March, on the third day of the third week of the third month, we explore the technologies used to create 3-D photographs, movies, and art, and we celebrate the many ways that these images have been viewed and enjoyed.

    We experience the world in three dimensions because we have two eyes that see from slightly different perspectives. These two points of view are combined in our brains, and the differences between what our eyes see are perceived as depth. This is called stereoscopic vision.

    Sir Charles Wheatstone created the first stereo 3-D drawings in 1838. During the second half of the 19th century, viewing 3-D photographs became a very popular form of home entertainment. The 20th century saw the invention of 3-D movies, comic books, holography, and more ways to view representations of the world in 3-D. Recent developments in virtual, augmented, and mixed reality offer new opportunities to create and interact with 3-D media. Advancements in 3-D technologies bring digital images to three-dimensional life, assisting surgeons, projecting art around the world, and educating students.

    What does the future of 3-D hold? New developments in stereoscopic capture and display methods will prove to inspire young scientists and storytellers to create the next generation of immersive stereoscopic content. 3-D technology may change the world.

    Spring cleaning has an entirely different meaning when celebrating the International Day of Nowruz. This global holiday is the annual start to a new year in many parts of the world.

    Nowruz (pronounced “no-rooz”) translates as “new day” and represents the first day of spring. The celebration falls on the vernal equinox which also aligns with the first day of the Iranian calendar.

    The event is filled with ancestral rituals, communal ceremonies and topped off with a special meal shared with neighbors and loved ones. The celebration of Nowruz dates back over 3,000 years in Western Asia and has become widespread all around the world.

    Being an annual tradition shared by millions of people, Nowruz represents more than an observance passed through generations. It serves as a reminder that rebirth in nature is an optimistic occurrence.

    As winter comes to a halt and life begins anew, Nowruz is the opportunity to synchronize with nature’s surroundings. It’s about strengthening bonds, rekindling friendships and taking on new opportunities.

    “Since it signifies a new beginning, Nowruz is also a festival that is filled with hope, as expressed in the gentle and elegant words of the Persian poet Hafez: “Springtime is here again/With the charm of roses./Look at their fresh cheeks/And the bitter plant of sadness/Will be uprooted from your heart”. The fires that are lit at Nowruz in the Iranian countryside, on the northern plains of Iraq and on the beaches of Los Angeles burn up the bad luck and suffering of the previous year and carry the promise of future joy and a more peaceful world.” -Audrey Azoulay, Director General of UNESCO, on the occasion of the International Day of Nowruz


    Check to see if any Persian restaurants in your area are celebrating. Iranians love to share their cultural experiences. Use #DayOfNowruz to share on social media.


    The United Nations officially recognized the International Day of Norwuz as an international holiday in 2010. The initiative was proposed by numerous countries who share the holiday including Afghanistan, Albania, Azerbaijan, India, Iran (the Islamic Republic of), Kazakhstan, Kyrgyzstan, Tajikistan, Turkey, and Turkmenistan.

    3…2…1…National Countdown Day on March 21 ticks down the minutes, seconds, or days to events big and small.

    3…2…1. July 16, 1969, Apollo 11 launches into the atmosphere carrying the crew for the first moon landing.

    3…2…1. Y2K, everyone partied like it was 1999 until the new millennium arrived.

    3…2…1. January 19, 2013, Marlo Anderson quietly launched a website called National Day Calendar.

    3…2…1…it is 5 o’clock somewhere!

    On National Countdown Day, 03/21, we can start a countdown to just about anything. Around the office, we countdown to the next celebration every day! It is also a day to consider past and present countdowns of significance.

    Recently, parts of the United States counted down to August 21, 2017, to a total solar eclipse. The event created road trip opportunities for those within driving distance. It also created science party lessons on rooftops in the path of the eclipse. And it was a memorable countdown, indeed. Did you miss it? Start your countdown for April 8, 2024. This solar eclipse will cover parts of Mexico, Central and Northeastern United States, and just a bit of Canada.


    Since royal weddings draw a lot of attention, countdowns are an essential part of the draw. The fanfare and commitment to tradition remind us of storybook weddings. There are several royal weddings to recall: Prince Charles and Lady Diana Spencer on July 29, 1981; Prince William and Catherine Middleton, April 29, 2011; Prince Harry and Meghan Markle on May 19, 2018.

    Another British countdown that kept the world interested was the countdown to Brexit.


    Some favorite countdowns in the U.S. lead to opening days – this could be the opening day of baseball, racing, the swimming pool, or hunting season. However, the countdown to tax day, election day, or even the closing bell can be a positive or ominous one. Of course, it all depends on the outcome. Sometimes one countdown even depends on the results of the other countdowns!


    Now, countdowns to summer break may be started as early as September 1 or as late as spring break. Those who motor on two wheels like to countdown to Sturgis. Other sports enthusiasts like to countdown to March Madness, Gameday, and Olympic Opening Ceremonies. There is also the countdown to the final buzzer of every game! However, there are sports with no time limit and therefore no countdown to end the game. Can you name one?

  • World Poetry Day | March 21

    World Poetry Day on March 21st serves as a reminder of the magnitude that reading and writing poetry has enriched and inspired the way we live our lives. Ever since humans have been recording history, poetry has challenged the norm with new ways of thinking through allegory and complex emotion. Words have always been the binding source between people and allows us to see life from a new perspective. Poetry is the artistic mastery of this phenomena, by conveying emotions within us and creating the ability to influence others. It’s our poetic nature that allows words to be the bridge to our feelings.

    “Poetry is a window onto the breath-taking diversity of humanity.” — Irina Bokova, UNESCO Director-General

    Poetry is not only an expression of art, but it also acts as an avenue of educating beyond the classroom setting. It allows us to take the knowledge we’ve been given and apply it directly to how we view the world. On this day we step into the realm of creative expression and open up to the inspiration that surrounds us, by sharing, collaborating and experiencing the world through poetry.


    Use #WorldPoetryDay to share on social media.  Read or recite poems.  Try your hand at writing a poem. As numerous as the days, there are as many styles of poetry. Find one that you enjoy!

    Humans have been recording poetry since the beginning of time. So pick a year, any year, and delve into a new, undiscovered headspace. Then, break out some parchment and a quill for your own expression session!


    The United Nations Educational Scientific And Cultural Organization (UNESCO) declared World Poetry Day to be observed annually on March 21.  This declaration took place in 1999 in Paris, France during UNESCO’s 30th Session.  Click here to read more on the United Nations Website.

  • NATIONAL AG DAY – Changes Annually


    Each year, National Ag Day recognizes and celebrates the abundance provided by agriculture across the United States. American agriculture plays a critical economic and food security role in our country.

    The role of American agriculture is greater than the food on our tables. It runs deep in our communities, large and small. Just about every product we touch involves a farmer. From the clothes on our backs to the fuel in our cars and the medicines we take, agriculture grows our economy and keeps us healthy. Agriculture provides jobs from field to store and beyond. In every area of agriculture, innovation is happing every day. And it’s been that way since the first farmer decided to plant a seed in the ground. 

    Farm co-ops, universities, 4-H clubs, agricultural associations, FFA clubs, businesses, and other organizations at the city, county, and state levels celebrate with a variety of events that give the general public an opportunity to see how their food, clothing, and other products get from the farm to you.

    While you may live in an urban area, agriculture is all around us. Events supported by organizations will demonstrate the economic impact agriculture has on society.

    HOW TO OBSERVE #NationalAgDay

    • Check your local newspaper or online listings for events near you. 
    • Encourage students to join FFA or 4-H for hands-on experience with agriculture. They may find their future there.
    • Volunteer to organize an event in your community.
    • Support your local farmer’s market.
