Bicycle Day

Bicycle Day commemorates the date of April 19, 1943. On this date Swiss chemist Albert Hofmann I intentionally ingested 0.25 milligrams (250 micrograms) of The psychedelic drug (or entheogen) lysergic acid diethylamide (LSD) in order to determine the properties of LSD. Hofmann had first synthesized LSD on November 16, 1938 in the Sandoz (now Novartis) laboratories in Basel, Switzerland.

However it wasn’t until 19 April 1943 that he discovered the psychedelic properties of LSD When. Less than an hour after taking it Hofmann experienced sudden and intense changes in perception. He asked his laboratory assistant to escort him home and, as use of motor vehicles was prohibited because of wartime restrictions, they had to make the journey on a bicycle. On the way, Hofmann’s condition rapidly deteriorated as he struggled with feelings of anxiety, alternating in his beliefs that the next-door neighbor was a malevolent witch, that he was going insane, and that the LSD had poisoned him. When the house doctor arrived, however, he could detect no physical abnormalities, save for a pair of incredibly dilated pupils. Hofmann was reassured, and soon his terror began to give way to a sense of good fortune and enjoyment, as he later wrote…

“…Little by little I could begin to enjoy the unprecedented colors and plays of shapes that persisted behind my closed eyes. Kaleidoscopic, fantastic images surged in on me, alternating, variegated, opening and then closing themselves in circles and spirals, exploding in colored fountains, rearranging and hybridizing themselves in constant flux …”

This bicycle ride home, convinced Hofmann that he had indeed made a significant discovery: a psychoactive substance with extraordinary potency, capable of causing significant shifts of consciousness in incredibly low doses. Hofmann foresaw the drug as a powerful psychiatric tool; because of its intense and introspective nature, he couldn’t imagine anyone using it recreationally.

The celebration of Bicycle Day originated in DeKalb, Illinois, in 1985, when Thomas B. Roberts, then a Professor at Northern Illinois University, invented the name “Bicycle Day” when he founded the first Bicycle Day celebration at his home. Several years later, he sent an announcement made by one of his students to friends and Internet lists, thus propagating the idea and the celebration. Bicycle Day is increasingly observed in psychedelic communities as a day to celebrate the discovery of LSD.


John Parker Day commemorates the date of 19 April 1775 when Captain John Parker of the Lexington MA militia gathered his band of farmers and townsfolk on the Lexington Common to confront British regulars under Colonel Francis Smith, who are marching to Concord, about six-and-a-half miles further up the road, to search for weapons and supplies rumored to be hidden there. No one knows who fired the first shot, but eight of Parker’s militiamen are killed, and ten wounded. No British soldiers are hit by militia shots. Later that day, Parker lead his men to ambush the British as they returned from Concord, and they were also engaged during the British Siege of Boston. Five months after “the shot heard round the world,” John Parker dies of consumption.

National Beer Day

National Beer Day is celebrated in the United States every year on April 7, marking the day that the Cullen–Harrison Act was enacted after having been signed into law by President Franklin D. Roosevelt on March 22, 1933. This led to the Eighteenth Amendment being repealed on December 5, 1933, with ratification of the Twenty-first Amendment to the U.S. Constitution. April 6, the day prior to National Beer Day, is known as New Beer’s Eve. Upon signing the legislation, Roosevelt made his famous remark, “I think this would be a good time for a beer.” The law went into effect on April 7 of that year in states that had enacted their own law allowing such sales. The beer could contain up to 3.2% alcohol by weight (or 4.05% by volume) compared to the 0.5% limit of the Volstead Act, because 3.2% was considered too low to produce intoxication. People across the country responded by gathering outside breweries, some beginning the night before. On that first day, 1.5 million barrels of beer were consumed, inspiring the future holiday. Today, April 7 is recognized as National Beer Day and April 6 is known as New Beer’s Eve.

The Cullen–Harrison Act, was named after its sponsors, Senator Pat Harrison and Representative Thomas H. Cullen, and was enacted by the United States Congress March 21, 1933 and signed by President Franklin D. Roosevelt the following day, legalized the sale in the United States of beer with an alcohol content of 3.2% (by weight) and wine of similarly low alcohol content, thought to be too low to be intoxicating, effective April 7, 1933. Upon signing the legislation, Roosevelt made his famous remark, “I think this would be a good time for a beer.”

According to the Cullen-Harrison Act, states had to pass their own similar legislation to legalize sale of the low alcohol beverages within their borders. Roosevelt had previously sent a short message to Congress requesting such a bill. Sale of even low alcohol beer had been illegal in the U.S. since Prohibition started in 1920 following the 1919 passage of the Volstead Act. On April 7, 1933, throngs gathered outside breweries and taverns for their first legal beer in 13 years. The passage of the Cullen–Harrison Act is celebrated as National Beer Day every year on April 7 in the United States.

However The Cullen-Harrison Act was not the official end of prohibition in the US (that happened on December 5, 1933 when the 21st Amendment was ratified). What the Cullen-Harrison Act did do was redefine an “intoxicating beverage” under the Volstead Act. As such, April 7 is a beer specific holiday and should not be confused with Repeal Day celebrated on December 5. National Beer Day was first created in 2009 by Justin Smith of Richmond, Virginia. After his friend, Mike Connolly, Smith started a Facebook page that was noticed by Colorado Beer Examiner, Eli Shayotovich. Smith’s promotion of the new holiday via various social media outlets was rewarded when the beer drinking app, “Untappd”, created a badge for National Beer Day that rewarded participants that checked a beer into the app on April 7. National Beer Day has since been trending every year on April 7 using the hashtag #NationalBeerDay. National Beer Day was officially recognized by Virginia Governor Terry McAuliffe and the Congressional Record by Congressman Dave Brat in 2017. In 2018, House Joint Resolution 90 was introduced in Virginia General Assembly to officially recognize National Beer Day in the Commonwealth of Virginia.

National Tartan Day was created 5 April 1982 in New York City to allow U.S. and Canadians of Scottish descent to celebrate their Scottish heritage and commemorate the anniversary of the 1320 signing of the Declaration of Arbroath on 5 April 1320 1320 which was signed by at least 8 earls and 31 barons. The Declaration of Arbroath was a letter in Latin to Pope John XXII, intended to confirm Scotland’s status as a sovereign nation, and defending Scotland’s right to use military force when unjustly attacked. Scotland’s leader Robert the Bruce is excommunicated for the murder of John Comyn before the altar in Greyfrairs Abbey, and the Pope recognizes Edward I of England’s claim of overlordship of Scotland
