Today’s sky, read against your chart.

Every day, the planets keep moving against the fixed positions in your birth chart. When a moving planet forms an aspect (a meaningful angle) to one of your natal points — a conjunction, trine, square, opposition, or sextile — that contact is a 'transit.' The transit forecast lists every active transit aspect to your chart on a chosen date, ranked by how tight the orb is, with a practitioner-written read of what the contact tends to mean in real life.

Your full natal chart computed once, then the live sky for the date you choose, then the cross-aspect detection between every transiting planet and every natal placement (Sun, Moon, all ten planets, Ascendant, Midheaven). Each detected aspect within standard orbs comes with a practitioner read tailored to that planet pair and the aspect's nature. Outer-planet transits (Jupiter through Pluto) get more weight because they're the windows that mark a season of life; inner-planet transits give the day's texture. Free as of v2.215.

Free horoscopes interpret the sky against your Sun sign — one twelfth of your chart. A transit forecast interprets the sky against your full chart, which means the same Saturn transit will read as your relational ground (if Saturn is hitting your 7th-house ruler), as a career window (if it's transiting your 10th), or as a body-clock recalibration (if it's hitting your 1st). Free horoscopes can't do that because they don't have your birth time. The compute and the interpretation both depend on the full natal — that's what the personalised forecast does, and on this site it's free.

Today is the most common — read the sky as of right now. But the transit machinery works for any date in the engine's range. Pick a future date if you want to see what's incoming on a specific weekend or before a decision; pick a past date to look back at a moment that mattered. The aspect orbs we use are tight enough that most transit aspects are 'in effect' for a window of days to weeks, depending on the planet's speed.

Arcsecond-grade. Both your natal chart and the transit positions are computed from VSOP87D for the planets and a truncated ELP2000 for the Moon — the same first-principles ephemerides professional astrology software uses. Aspect orbs default to 8° for major aspects with the luminaries (Sun/Moon), 6° for the personal planets, and tighter for the social/transpersonal planets. Tightest-first ranking puts the most exact aspects at the top.
