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.
There are typically 12 full moons and 12 new moons every year, but only four to seven eclipses. Total lunar eclipse composite image by Fred Espenak. A lunar eclipse happens when the Earth, sun and moon align in space, with Earth in the middle.
