"The loops are a tool to capture and correlate the flow of the entire Northern Hemisphere from cycle to cycle. Each individual cycle is dated and determined by the average cycle length. Each loop is manually animated in either direction by clicking on the arrow buttons. Each day in a cycle is numbered. Use the calendar to easily find and compare specific dates."
