One named tradition: Vettius Valens, Anthology, Book I, chapter 1 (2nd century). Short summaries of his lists.
Planetary hours are one of the oldest timekeeping customs of astrology. Each hour of the day is given to one of the seven visible planets in the Chaldean order, from the slowest to the fastest: Saturn, Jupiter, Mars, the Sun, Venus, Mercury and the Moon.
The same order gives the weekdays their names. Twenty-four hours after a day of the Sun, the next first hour falls to the Moon, then to Mars, Mercury, Jupiter, Venus and Saturn — Sunday, Monday, and in the Romance languages martedì, mercoledì, giovedì, venerdì and Saturday.
AstroSensus calculates the hours from the real sunrise and sunset at the chosen place. It shows only which planet rules the day and each hour, with what Vettius Valens said that planet signifies. There is no "best hour for money or love" here: this is a tradition, not advice.

The time from sunrise to sunset is cut into twelve equal hours, and so is the night from sunset to the next sunrise. The first hour after sunrise belongs to the planet of the weekday, and each next hour to the next planet in the Chaldean order: Saturn, Jupiter, Mars, the Sun, Venus, Mercury, the Moon.
Because daylight and night change length through the year. In summer the twelve day hours are long and the night hours short; in winter the other way round. Only at the equinoxes are they close to 60 minutes.
In the tradition a day begins when the Sun rises. Until the next sunrise you are still in the night hours of the previous planetary day, even after midnight.
No. The page shows which planet the tradition assigns to an hour and what Vettius Valens says the planet signifies. It is a historical tradition, not advice, and nothing shows that the hour itself changes how anything turns out.
