Mole Day
Mole Day is celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m. It celebrates Avogadro’s Number (6.02 x 1023), which is a basic measuring unit in chemistry. Mole Day was created as a way to foster interest in chemistry, and schools throughout the United States and around the world celebrate with various activities related to chemistry and/or moles.
For a given molecule, one mole is a mass (in grams) whose number is equal to the atomic mass of the molecule. For example, the water molecule has an atomic mass of 18, therefore one mole of water weighs 18 grams. An atom of neon has an atomic mass of 20, therefore one mole of neon weighs 20 grams. In general, one mole of any substance contains Avogadro’s Number of molecules or atoms of that substance. This relationship was first discovered by Amadeo Avogadro (1776-1858) and he received credit for this after his death.

Earth creation day
The Ussher chronology is a 17th-century chronology of the history of the world formulated from a literal reading of the Bible by James Ussher, the Archbishop of Armagh (Church of Ireland). The chronology is sometimes associated with young Earth creationism, which holds that the universe was created only a few millennia ago by God as they believe is described in the first two chapters of the Biblical book of Genesis.
The full title of Ussher's work is Annales Veteris Testamenti, a prima mundi origine deducti, una cum rerum Asiaticarum et Aegyptiacarum chronico, a temporis historici principio usque ad Maccabaicorum initia producto. (""Annals of the Old Testament, deduced from the first origins of the world, the chronicle of Asiatic and Egyptian matters together produced from the beginning of historical time up to the beginnings of Maccabes"")
Ussher's work was his contribution to the long-running theological debate on the age of the Earth. This was a major concern of many Christian scholars over the centuries.
The chronology is sometimes called the Ussher-Lightfoot chronology because John Lightfoot published a similar chronology in 1642â??1644. This, however, is a misnomer, as the chronology is based on Ussher's work alone and not that of Lightfoot. Ussher deduced that the first day of creation began at nightfall on Saturday, October 22, 4004 BC, in the proleptic Julian calendar, near the autumnal equinox. He elsewhere dates the time to 6 pm. Lightfoot similarly deduced that Creation began at nightfall near the autumnal equinox, but in the year 3929 BC.
Ussher's proposed date of 4004 BC differed little from other Biblically based estimates, such as those of Jose ben Halafta (3761 BC), Bede (3952 BC), Ussher's near-contemporary Scaliger (3949 BC), Johannes Kepler (3992 BC) or Sir Isaac Newton (c. 4000 BC).[1] Ussher's specific choice of starting year may have been influenced by the then-widely-held belief that the Earth's potential duration was 6,000 years (4,000 before the birth of Christ and 2,000 after), corresponding to the six days of Creation, on the grounds that ""one day is with the Lord as a thousand years, and a thousand years as one day"" (2 Peter 3:8). This view continued to be held as recently as AD 2000,[2][3] six thousand years after 4004 BC.
