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:
“Oh, life is a glorious cycle of song,
A medley of extemporanea;
And love is a thing that can never go wrong;
And I am Marie of Roumania.”
—Dorothy Parker (1893–1967)
“Unless a group of workers know their work is under surveillance, that they are being rated as fairly as human beings, with the fallibility that goes with human judgment, can rate them, and that at least an attempt is made to measure their worth to an organization in relative terms, they are likely to sink back on length of service as the sole reason for retention and promotion.”
—Mary Barnett Gilson (1877–?)
