The internationally accepted Gregorian calendar may be split into 12 months, but things were almost very different. If the world followed the International Fixed calendar, we'd have 13 months. In this alternative system, each month includes the exact same number of days, which is 28 instead of 30 or 31 like we have now. The calendar was created by Moses Cotsworth, a North Eastern Railway advisor who was annoyed by the way months with different numbers of days affected his paychecks. (Aren't we all, Cotsworth. Aren't we all.)
