Known as Kodomo no Hi, this Japanese national holiday celebrates the happiness and individual strengths of children. Families fly colorful koinobori (carp-shaped streamers) outside their homes. The carp symbolizes determination and vigor. Traditional foods like kashiwa-mochi (rice cakes wrapped in oak leaves) are prepared, and families wish for the health and success of their children.

Today, the holiday is marked by patriotic ceremonies, speeches, parades, and the display of national flags. It serves as a symbol of national identity and the enduring pursuit of sovereignty.
Paraguay (May 14–15)

Paraguay’s Independence Day is uniquely celebrated over two days, reflecting key moments in 1811 when the country broke free from Spanish rule. Festivities include parades, traditional music, and cultural performances that highlight Paraguay’s heritage. Government buildings and homes are decorated in national colors, and communities gather for food, dance, and historical reenactments honoring the nation’s founding.
Norway (May 17)

Known as Syttende Mai, Norway’s Constitution Day celebrates the signing of the Norwegian Constitution in 1814. Unlike many national days, it is marked by festivities centered on children, community, and national pride rather than military displays. Parades featuring schoolchildren, traditional folk costumes (bunads), and marching bands take place across the country. Families gather for meals, ice cream, and flags, creating a joyful and distinctly local atmosphere.
Cameroon (May 20)

Cameroon’s National Day, also known as Unity Day, commemorates the 1972 referendum that transformed the country from a federal system into a unified republic.

Celebrations include large military parades, presidential addresses, and performances showcasing regional traditions, reinforcing a shared national identity.
Yemen (May 22)

Yemen’s Unity Day marks the unification of North and South Yemen in 1990, forming the modern Republic of Yemen.

Eritrea (May 24)

Eritrea’s Independence Day marks the end of a grueling 30-year struggle for sovereignty. On this day in 1991, independence forces successfully entered the capital, Asmara. Citizens celebrate their hard-won freedom with massive street carnivals, traditional music, dancing, and official flag-raising ceremonies.
Jordan (May 25)

Jordan’s Independence Day marks the country’s emergence as a fully sovereign state. On May 25, 1946, a treaty ended the British mandate, recognizing the Hashemite Kingdom of Jordan.

Georgia Independence Day in 2026 marks the anniversary of the country’s declaration of independence on May 26, 1918, when the Democratic Republic of Georgia was established. The day is celebrated across the country, with major events centered in Tbilisi, including official ceremonies, military parades, and speeches by government leaders. In 2026, the celebrations are expected to highlight national pride and resilience, alongside public concerts, cultural showcases, and traditional Georgian food that bring communities together.
Azerbaijan (May 28)

Azerbaijan commemorates the founding of the Azerbaijan Democratic Republic in 1918—the first secular democratic republic in the Muslim world. Although the republic was short-lived, the date remains a cornerstone of national identity. Celebrations include official ceremonies, concerts, and public events that honor the country’s independence, culture, and modern achievements.
Ethiopia (May 28)

Ethiopia’s National Day, often referred to as Derg Downfall Day, marks the fall of the Derg regime in 1991. This moment ended years of authoritarian rule and ushered in a new political era. The day is observed with public gatherings, speeches, and cultural events that reflect on the country’s recent history and ongoing path toward stability and development.
How Holidays Affect Travel, Business & Banking

Global holidays significantly impact daily operations. Proper planning prevents unexpected delays.
In the United States, Memorial Day weekend is consistently one of the busiest travel periods of the year. Government offices, banks, and the stock market close on May 25. Postal services and standard shipping logistics are also suspended for the day.
International travel requires similar awareness. During religious observances like Eid al-Adha, businesses across the Middle East and parts of Asia close entirely or operate on reduced hours for several days. Major cultural holidays, such as Norway’s Constitution Day or Ascension Day in parts of Europe, also lead to closed banks, halted mail delivery, and modified public transport schedules. Reviewing local calendars before booking international trips or finalizing business deadlines will save you time and frustration.
Frequently Asked Questions (FAQs)
