Query: 2. The Shift From Lunar to Solar Calendars and Counting

Key Concept Missing in Chapter Body

Quoted text:

Ultimate dissolution: At the end of the Roman Republic, Julius Caesar began the year with a new moon, trying to reconcile the irreconcilable lunar and solar calendars. This delayed January 1 10 days behind the December 21 winter solstice. (Later, Islam’s retrogression to a lunar cycle abandoned all solar moorings.)

Some of this is discussed in generality, but we’d like to see these specifics from the Key Concepts section about Julius Caesar (and his Julian calendar) and Islam in this chapter’s body; can you help us insert it in this chapter’s body? See also Chapter 1 for a cohesive discussion on both.
