Mole Day Mole Day is celebrated yearly on Oct. 23 from 6: 02 a.m to 6: 02 p.m.. The idea of a celebratory day was put forward by a chemistry teacher in 1991 and has been honored every year since. It celebrates Avogadro's Number, which is a basic measuring unit in chemistry. Each Mole Day has a specific theme. Pi Day The grandaddy of mathematical and scientific holidays, however, falls every year on Mar. 14. The date, 3/14, represents the first three numerals in the calculation of pi, so the date is known annually as Pi Day. Pi Day was founded in 1988 by a physicist. The observations spread to the point where on Mar. 12, 2009, the U.S. House of Representatives passed a resolution declaring Mar. 14 as National Pi Day. Fibonacci Day Nov. 23 marks Fibonacci Day, a special day that celebrates the man known as Fibonacci who developed a mathematical idea called the Fibonacci Sequence, in which every number is the sum of the previous two numbers. So, for example. 11/23 marks the day because 1+1 equals 2, and then 1+2 equals 3（the date being the 23rd）. Square Root Day Square Root Day is a holiday that heartily honors those dates where the combination of day and month and year form square roots: e.g. 2/2/04 and 3/3/09. The last Square Root Day was 4/4/16. The holiday was created by a high school teacher Ron Gordon. Square Root Day has its own website where celebrants can gather before the next holiday. 1．How is Mole Day similar with Pi Day? A．They both have themes. B．They are y
