I need help understanding and using the Cosmic Calander (ans in figuring out the dates certain events such as when our solar system was created). Can someone plz help me with this? Thnx in advance.

I assume you are refering to Carl Sagan's "cosmic calendar" in which all the events since the Big Bang are compressed into one calendar year. Jan 1 is creation and Dec 31 is today. The solar system in this case was created in August. See
