This is what they say about it on Wikipedia:
In photography, the golden hour (sometimes known as magic hour, especially in cinematography) is the first and last hour of sunlight during the day,[1] when a specific photographic effect is achieved with the quality of the light.It's pretty darn easy to find out when sunrise and sunset is. Just check your local newspaper or the internet. Here is a link to a website that will tell you the golden hour anywhere in the world. It's kind of interesting and you might enjoy playing around with it... then again... maybe not.
Typically, lighting is softer (more diffuse) and warmer in hue, and shadows are longer. When the Sun is near the horizon, sunlight travels through more of the atmosphere, reducing its intensity, so that more of the illumination comes from the sky. More blue light is scattered, so that light from the Sun appears more reddish. And the Sun's small angle with the horizon produces longer shadows. The golden hour is a mild version of alpenglow, as described by Galen Rowell.
“Hour” is used here quite loosely. The character of the lighting is determined by the Sun's altitude, and the time for the Sun to move from the horizon to a specified altitude depends on a location's latitude and the time of year[2] (Bermingham 2003, 214). In Los Angeles, California, at an hour after sunrise or an hour before sunset, the Sun has an altitude of about 10°–12°.[3] For a location closer to the equator, the altitude is greater (or the time less), and for a location farther from the equator, the altitude is less (or the time greater). For a location sufficiently far from the equator, the Sun may not reach an altitude of 10°, and the golden hour lasts for the entire day if the Sun indeed rises.
In the middle of the day, the bright overhead Sun can create too-bright highlights and dark shadows. The degree to which overexposure can occur varies because different types of film and digital cameras have different dynamic ranges. This harsh-lighting problem is particularly important in portrait photography, where a fill flash is often necessary to balance lighting across the subject's face or body, filling in strong shadows that are usually considered undesirable.
Because the contrast is less during the golden hour, shadows are less dark, and highlights are less likely to be overexposed. In landscape photography, the warm color of the low Sun is often considered desirable to enhance the colours of the scene.

It's Friday and we're lookin' down the barrel of a three-day weekend. At least I am... and I hope you are too! Try to get some shooting in and I'll see you Tuesday!
