Metric System Day
Metric System Day is observed annually on October 10 (10/10). The date symbolizes the base-10 (decimal) structure of the metric system, which is built on powers of ten. Promote awareness and understanding of the metric system. Encourage its adoption and proper usage, especially in countries where it’s not the primary measurement system. The metric system, formally known as the International System of Units (SI), was first adopted in France in the late 18th century. Today, it’s the standard system of measurement used in most of the world.

Beaver Day
Beaver Day is commonly observed as International Beaver Day on April 7 each year. It’s a day dedicated to appreciating beavers and recognizing their crucial role in ecosystems. The purpose is to raise awareness about the importance of beavers as “ecosystem engineers” and support conservation efforts for beavers and their habitats. Founded by wildlife advocate Beaver Believers and supported by groups like Beavers: Wetlands & Wildlife (BWW). Beavers help restore wetlands, improve water quality, and provide habitats for other species through dam building.

Beer Day
National Beer Day is celebrated in the United States on April 7 each year. It commemorates the day in 1933 when the Cullen–Harrison Act went into effect, allowing people to legally buy, sell, and drink beer again after Prohibition — as long as it had an alcohol content of 3.2% (by weight) or less. President Franklin D. Roosevelt signed the act on March 22, 1933, saying, “I think this would be a good time for a beer.” The law became effective on April 7, making that the first day in 13 years Americans could legally enjoy beer again. It was a major step toward the full repeal of Prohibition, which officially ended on December 5, 1933 with the 21st Amendment.
