Moon Phases Explained: A Complete Guide to the Lunar Cycle
moon phases happen because the Moon orbits Earth, and we see different amounts of its sunlit side as its position changes relative to the Sun and Earth. The complete cycle — from one New Moon to the next — takes about 29.53 days, called a synodic month. There are eight recognized phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent.

Full Moon names come primarily from Native American and colonial American traditions, with each month's Moon reflecting seasonal events like animal behavior, plant cycles, or weather. The most widely used set includes the Wolf Moon (January), Snow Moon (February), Worm Moon (March), Pink Moon (April), Strawberry Moon (May), Buck Moon (June), Sturgeon Moon (July), Sturgeon Moon (August), Corn Moon (September), Hunter's Moon (October), Beaver Moon (November), and Cold Moon (December). Many cultures worldwide have their own naming systems.

A supermoon is a Full Moon that occurs when the Moon is at or near its closest point to Earth (perigee) in its elliptical orbit. Supermoons appear up to 14% larger and 30% brighter than a Full Moon at its farthest point (apogee). The scientific term is perigee-syzygy, and there are typically 3 to 4 supermoons each year. While the size difference is real, most people cannot notice it without a direct comparison.
Read guide →Understanding sunrise and sunset times
The sunrise and sunset times shown on this page are computed from your selected city's geographic coordinates using standard solar geometry equations. Times are displayed in the city's local timezone and automatically account for daylight saving time.
What are golden hour and blue hour?
Golden hour is the period shortly after sunrise and before sunset when the sun is low on the horizon, producing warm, soft, directional light ideal for photography. Blue hour is the period just before sunrise and just after sunset when the sky takes on a deep blue color — perfect for cityscape and moody landscape photography. Our calculator shows the exact timing of both for any city and date.
Why sunrise and sunset times change daily
The times change because of the Earth's axial tilt (23.4°) and its elliptical orbit around the Sun. In summer, the sun takes a higher, longer path across the sky, producing earlier sunrises and later sunsets. In winter, the path is lower and shorter. At the equator, the change is minimal (~12 hours year-round). At high latitudes, the change can be extreme — from 24-hour daylight in summer to complete darkness in winter.
