Cycle Length
However, regardless of the culture, all lunar months approximate the mean length of the synodic month, or how long it takes to pass through each phase (new, half, full moon) and back again. It takes 29.53059 days (29 days, 12 hours, 44 minutes and 3 seconds). Interestingly, the moon finishes its orbit around the earth in 27.3 days, but it has not finished a full cycle until it reaches the point in its orbit where the sun is in the same position.

Famous quotes containing the words cycle and/or length:
“The Buddha, the Godhead, resides quite as comfortably in the circuits of a digital computer or the gears of a cycle transmission as he does at the top of a mountain or in the petals of a flower.”
—Robert M. Pirsig (b. 1928)
“To find the length of an object, we have to perform certain
physical operations. The concept of length is therefore fixed when the operations by which length is measured are fixed: that is, the concept of length involves as much as and nothing more than the set of operations by which length is determined.”
—Percy W. Bridgman (1882–1961)
