Each planetary day begins at Sunrise over the sea Sunrise, also called sunup in some American English dialects, is the time at which the first part of the Sun appears above the horizon in the east. Sunrise should not be confused with dawn, which is the (variously defined) point at which the sky begins to... sunrise, and ends at the next day's sunrise. For example, Sunrise on Saturday is the beginning of the day of Saturn. Before sunrise on Saturday, you are still under the day of Venus.

The day is divided into two parts; the day (time between sunrise and A red sunset panorama Sunset, also called sundown in some American English dialects, is the time at which the Sun disappears below the horizon in the west. It should not be confused with dusk, which is the (variously defined) point at which darkness falls, some time after the Sun itself... sunset) and the night (time between sunset and tomorrow's sunrise). Each part of the day is then divided into 12 equal parts, for a total of 24 (unequal) hours.

The first planetary hour of the day is always the same as the planetary day; so sunrise on Monday is the beginning of both the day of the Moon and the hour of the Moon. The hours repeat infinitely in this order:

• Saturn
• Jupiter
• Mars
• Sun
• Venus
• Mercury
• Moon

So the second planetary hour of the day of the Moon is the hour of Saturn, the third would be the hour of Jupiter, and so on.
