Cosmic CalendarThe Cosmic Calendar is a teaching tool that compresses the entire 13.8-billion-year history of the universe into a single calendar year. The Big Bang falls on January 1st at midnight, and the present day falls on December 31st just before midnight. Each month represents roughly 1.15 billion years. Each day represents about 37.8 million years. This section tells you exactly where the lesson falls on that calendar and gives you a word-for-word script to read aloud to your learner. You can display a printed calendar (there is a printable on the website), draw one on a whiteboard, or simply describe it as you read. Lessons 4 and 9 are conceptual lessons with no calendar date; a note is included for those lessons explaining why.
