Working as a zookeeper requires you to be passionate about animals and wildlife conservation. You often spend more time with the animals than other zoo employees, getting to know their habits and personalities. This helps you determine when the animals are healthy or whether they need veterinary care, a vital role of primary caregivers.
So on average the number of days between two similar phases (e.g. between one full moon and the next full moon) is about 29.531 days. This period is referred to as a lunation, lunar month, or synodic month.
For the best answers, search on this site https://shorturl.im/pnfj8. The Full Moon occurs every 29.5 days. It is therefor possible, but unlikely, for there to be no full moons in February. When this happens there are two in January and two in March. Any thirty or 31 day month can have two full moons. The Moon takes 27.3 days to orbit Earth. The difference between this and the interval for phases is due to the Earth's own motion around the Sun, carrying the Moon with it, so that a slightly different position is needed for the phase to repeat.
