Eid al Fitr, also known as just Eid, is the celebration of the breaking of the fast, which symbolizes a return to faith and gives Muslims a chance to give thanks to Allah. It encourages charitable giving, fosters a sense of community, and facilitates spending time with loved ones. Common Eid customs include exchanging gifts, wearing new clothes, and indulging in cultural treats.

The prophet Muhammad instituted Eid al-Fitr in 624 CE as a way to break the Ramadan fast. This holiday is very significant to Muslim communities in America because it permits people to fulfill their religious obligations while simultaneously fostering the growth of their cultural customs and traditions in their new country. Eid, then, is essentially a singular intersection of American diversity and Islamic customs, exhibiting a congruent fusion of religious observance and vibrant culture.

13th April - Cambodian New Year

The traditional Lunar New Year celebration in Cambodia is known as Choul Chnam Thmey, or Cambodian New Year. One of the most significant holidays in Cambodia is observed during this period, which marks the end of the harvest season when farmers can enjoy the fruits of their labor before the start of the rainy season.

The origins of the Cambodian New Year can be found in the period of Brahminism, which greatly influences the celebrations of the culture as a whole, which include both religious and secular customs. The holiday is significant to Cambodian-Americans because it allows them to honor their new home in America while also maintaining ties to their cultural heritage. By showcasing traditional music, dance, food, and costumes, it acts as a link for the younger generation to stay connected to their Cambodian heritage.

Cambodian communities in the United States host exuberant celebrations of the Cambodian New Year, primarily in Long Beach, California; Lowell, Massachusetts; and Philadelphia, Pennsylvania, among other places. By introducing American audiences to genuine Cambodian customs, these cultural events encourage mutual understanding through cross-cultural exchange. Like in Cambodia, the celebration usually takes place in April, depending on the lunar calendar, soon after the spring equinox.

13th April - Songkran (Lao/Thai New Year)

Lao New Year marks the beginning of the monsoon season and the conclusion of the dry season. It is a time for purification and rebirth, known as Pii Mai. It takes place over three days. People hold ceremonies, throw parties, and offer prayers at temples during this time. Dousing people in water is another prevalent custom.

The origin of Lao New Year is rooted in a legend about Thao Kabinlaphrom. His daughters were left to take care of his severed head after he lost a bet and his life. They took great care not to let it touch the ground because doing so would have caused great destruction to the world. Every year on April 13th, Lao New Year is observed, during which this tale is acted out.

14th April (Judaism) – Passover

A week-long observance of the Israelites’ liberation from slavery in Egypt, as described in the Hebrew Bible.

15th April - Tax Day

The deadline for filing income taxes in the US is Tax Day. The Revenue Act of 1861 and the American Civil War are key points in the history of the US income tax. This tax was put in place to aid with the war's expenses. The US Constitution's 16th Amendment was ratified and made law in 1913 following multiple repeals, additional taxes, and more repeals. This created Congress's authority to impose the federal income tax.

The US government still primarily raises its funds through the income tax. A Tax Day was established to make sure that all money owed for the previous year is paid. By this date, all US taxpayers must file their taxes using their earnings from the previous year. This date has always fallen on April 15 of each year. The following Monday is the new due date if this day falls on a weekend. The Emancipation Day holiday in Washington, DC, has an impact on this date as well.

17th April - National and World Haiku Poetry Day

Haiku Poetry Day

The goal of National Haiku Poetry Day is to honor haiku poetry. Haiku is a type of poetry that dates back to the 17th century in Japan. Traditionally, it is a three-line poem with a 5-7-5 structure and seventeen syllables. Haikus frequently place a strong emphasis on directness, intensity, and simplicity. The purpose of this day is to promote the benefits of haiku. It inspires poets to read, write, and perform their poetry at all levels.

The Haiku Foundation created National Haiku Poetry Day in 2012. It is celebrated on April 17 of each year.

We will have the chance to consider the theme and work with these priceless artifacts in 2024.

18th April - National High Five Day

The goal of National High Five Day (NH5D) is to foster optimism, goodwill, and unity. It makes use of the common "high five" gesture to promote interpersonal ties and kindness. The celebration is very important because it makes people feel like they belong, makes them happy, and highlights how easy it is to show support, unity, or affirmation with a physical gesture.

The origins of NH5D can be traced to a group of University of Virginia students who decided to establish a holiday honoring this affirmative action in 2002. It quickly gained traction and resonated with Americans all over the country, demonstrating the high five's cultural significance. The high five is a common symbol of accomplishment, teamwork, and mutual excitement in America, which makes NH5D the ideal combination of positivity and American culture.

In America, communities and individuals celebrate National High Five Day by proactively giving high fives to each other throughout the day. To promote widespread participation, events are frequently planned at public places, businesses, and educational institutions. These activities promote positivism and strengthen unity while upholding the observance's spirit. Every year on the third Thursday in April, people celebrate NH5D.

19th April - Bicycle Day

Celebrated on Bicycle Day, it honors the day that Swiss chemist Albert Hofmann intentionally consumed LSD-25, also known as Lysergic Acid Diethylamide. Hofmann had inadvertently come into contact with the synthetic chemical LSD while conducting research on ergot fungus as a means of producing an anti-hemorrhaging medication. After experiencing some side effects, including vertigo and agitation, Hofmann took what he thought to be a safe dosage—.25 milligrams—a few days later.

Bicycle Day honors Hofmann's 1943 LSD experience, which is recognized as the original acid trip. Following consumption, Hofmann experienced anxiety and paranoia and asked his helper to go home with him. T

Thomas B. Roberts, a professor at Northern Illinois University, established Bicycle Day in 1985. He began the day by celebrating his first conscious LSD exposure. It is celebrated on April 19 of each year.

World Bicycle Day: History, Significance, Theme, Quotes and Celebrations

22nd April - Passover (Start)

The seven-day Jewish holiday known as Passover (Hebrew: מסח) commemorates the Israelites' flight from Egypt some 3,300 years ago. The reason Passover got its name is that the Israelites used signs to mark the frames of their doors. It is thought that during the plague of the firstborn, God passed over their homes as a result of this sign.

Up until Moses, the Israelites were servants of Jacob. They experienced starvation in Israel and most of Mesopotamia. In Egypt, the Israelites constructed grain storage cities—possibly the pyramids. The Israelites had developed a servitude mentality after 210 years of captivity in Egypt and did not think they could escape. Eventually, they made their way out of the Sinai Wilderness, where they spent the next forty years.

Every year, the last week of April is dedicated to World Immunization Week, with themes like "Protected Together, #VaccinesWork" Typically, the event includes a range of national, regional, and international initiatives designed to support and strengthen long-term immunization campaigns.

The goal of World Penguin Day is to honor the aquatic, avian birds. Because they can be both predators and prey, penguins are essential to their environments. They hunt fish like squid and krill and give food to leopard seals. Climate change could have an impact on penguins. The World Wide Fund for Nature (WWF) states that if the temperature rises above 35.6 degrees Fahrenheit (2 degrees Celsius), up to 75% of the Adelie penguin population will eventually decline and disappear.

25th April - World Malaria Day

The goal of World Malaria Day is to increase public awareness of malaria, one of the deadliest diseases in the world. Plasmodium, a parasite, is the cause of malaria, a blood disease.

Jazz changed over time by absorbing many different styles, which helped it to become a major force in the larger field of American music. Given that America is home to numerous renowned jazz musicians who have made enormous contributions to the genre, this day is particularly notable.
