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:
“Only mediocrities progress. An artist revolves in a cycle of masterpieces, the first of which is no less perfect than the last.”
—Oscar Wilde (1854–1900)
“An ... important antidote to American democracy is American gerontocracy. The positions of eminence and authority in Congress are allotted in accordance with length of service, regardless of quality. Superficial observers have long criticized the United States for making a fetish of youth. This is unfair. Uniquely among modern organs of public and private administration, its national legislature rewards senility.”
—John Kenneth Galbraith (b. 1908)
