"The mole (symbol: mol) is the SI base unit that measures an amount of
substance. One mole contains Avogadro's number (approximately
6.022×1023) entities. A mole is much like a dozen in that both units
can describe any set of elementary objects, although the mole's use is
usually limited to measurement of subatomic, atomic, and molecular
structures, as a mole represents an exceedingly large number of
entities."

"Mole Day is an unofficial holiday celebrated among chemists in North
America on October 23, between 6:02 AM and 6:02 PM, making the date
6:02 10/23 in the American style of writing dates. The time and date
are derived from Avogadro's number, which is approximately 6.02×1023,
defining the number of particles (atoms or molecules) in a mole, one
of the seven base SI units."
