World Laboratory Day

World Laboratory Day is a worldwide holiday created in honor of laboratories. These scientific centers are a necessity in modern society: biomaterials are tested there, new drugs are developed, various experiments are conducted, and much more. It is celebrated every year on April 23rd.


The exact start date of World Laboratory Day is uncertain. Laboratories themselves have been around since ancient times. At that time, they were simply gloomy rooms filled with flasks and various tools. Alchemists worked there, similar buildings might have been built by healers. The oldest laboratory is believed to have belonged to Pythagoras (500 BC). The great scholar of ancient Greece tested his theories about sound tones and vibrations caused by strings there.

In the Middle Ages improvised laboratories became more and more numerous. However, they began to take their modern form in the 19th century. At that time, various sciences were actively developing, and the creation of research centers became a necessity.

After WWII, not only the number of laboratories increased significantly, but also their diversity in areas: medicine, ecology, meteorology, testing of newly developed devices, automotive engineering and much, much more.
