October

October generally means Fall weather, daylight hours growing shorter and trick-or-treating. If cars are more your thing, in 1908 on October 1 Henry Ford introduced the first Model T. This is also the month the American Gem Trade Association (AGTA) revised the birthstone list in the first revision since 1912 and added Tanzanite as a December birthstone. October is named after "octo" which is Latin for "eight" (the first month in the Roman calendar is March). When the Gregorian calendar was adoted in 1582, 10 days in October were skipped to correct for too many leap years over the centuries. The birth flower is Calendula or Cosmos. The modern birthstone is Opal (confidence, hope and faith) and the traditional birthstone is Tourmaline (safety, endurance and balance).
