How this horoscope is made
Most horoscopes do not say where they come from. This one is worked out from the real sky: the positions of the Moon and planets are calculated with the same engine as our birth chart calculator, which is checked against the Swiss Ephemeris. Your sign is treated as the first house of a chart, the next sign as the second house, and so on round the zodiac. This is the solar chart method astrologers use for Sun-sign forecasts. The house each planet, new moon or full moon falls in decides which part of life the reading is about.
The Moon changes sign every two to three days and sets the mood of each day. New and full moons, planets changing sign or direction, and exact aspects between planets mark the key dates of a week or month. Read it as tradition and a prompt for reflection, not as a prediction.

Questions
When is the Sagittarius daily horoscope updated?
Every day at midnight US Eastern time. The Moon moves into a new sign every two to three days, so the main reading changes often, while the parts about Venus, Mars and Mercury change over weeks.
Is this for Sagittarius Sun or Sagittarius rising?
It is written for Sagittarius as your Sun sign. Many astrologers suggest reading it for your rising sign too, since the same method works from the Ascendant.
