Join the celebrations
and commemorate
Avogadro's number
Mole Day
every 23 October
Each year on 23 October the Mole Day celebrations begin at 6.02am and finish at 6.20pm the next day!
You probably won't get the day off work or find your local drugstore flush with cards celebrating the occasion, but Mole Day is celebrated every year by chemists throughout the world. Since Avogadro's number is 6.022 × 10 23, it only makes sense that the holiday starts at 6:02 a.m.
Precise, huh? Well that’s because this all-important day has nothing to do with the animal, but commemorates Avogadro’s number (6.02 x 10 23) – a unit of measurement in chemistry.
- Today, October 23, is Mole Day — the unofficial holiday when we celebrate Amedeo Avogadro and his contributions to molecular theory. In 1811, Avogadro hypothesized that given two volumetrically.
- So, with that out of the way, here are 5 fun facts about the mole and Mole Day: 1. The mole is attributed to 18th century Italian scientist Amedeo Avogadro, whose full name is Lorenzo Romano Amedeo Carlo Avogadro di Queregna e di Cerreto.
Avogadro's Day
Does the word molecule ring a bell? The word mole comes from the word and if you’re like me and feeling a bit rusty since chemistry class, then an explanation will go a long way!
One mole is a mass – and the number of that mass is equal to the atomic mass of the molecule. So if we take an atom of neon – which has an atomic mass of 20, what will one mole equal? 20 grams of course!
The National Mole Foundation think it’s important to recognise the discovery by Amadeo Avogadro who didn’t receive recognition until after his death! The foundation also wants to raise awareness of chemistry. They want to get students and as many people as possible feeling enthusiastic about the subject!
This year’s theme will be: ‘Moley Potter’. So, will you pledge allegiance to the mole? Why not visit the Mole Day website for all the information you need about what’s happening this year.
In the meantime you could start planning your own mole-like activity. You could plan out a scavenger hunt, write a mole day song or plan some mole jokes to drop into conversation throughout the day. What is Avogadros favourite music? ‘Rock ‘n Mole’! What line from Shakespeare do high school moles have to memorize? ‘To mole or not to mole that is the question.’ You get the picture …

And just because the mole in question is about chemistry doesn’t mean you can’t use real live moles for inspiration! Organise your event and then dress as a mole. Who can come up with the best outfit? The race is on!
