Mole Day

Mole Day is marked on October 23 annually and is celebrated by chemists, chemistry students and chemistry enthusiasts across the world. The day is commemorated in honour of Avogadro's number and is marked from 6:02 a.m. to 6:02 p.m.

The aim is to make students interested in chemistry by directing various activities associated with moles and chemistry.

The day originated around the 1980s when an article appeared in The Science Teacher. Later, a retired high school chemistry teacher, Maurice Oehler from Wisconsin, USA, drew inspiration from the article and founded the National Mole Day Foundation. When written in American format, the day resembles the Avogadro number, which signifies the number of molecules or atoms contained in a mole.

The day is a special day for all the people associated with the subject of chemistry. Many activities related to moles and chemistry are conducted to mark this day.
