The Twelve Horae (or Horai) were goddesses of the hours of the day and possibly even the twelve months of the year. Their duty was to oversee the path of Helios, the sun god. They are the daughters of Chronos, the personification of time.

The ancient Greeks had their hours of the day fixed differently than we do today. They divided their hours into only twelve portions, rather than twenty-four, and it was identified by the position of the sun in the sky. This method had a major flaw. The actual length of the hour changed between summer days and winter days.
- The Horae are commonly confused with the Horae (Seasons), the goddesses of the seasons.
