  • is_mercury_retrograde

    Says whether Mercury is retrograde on a date and which phase it is in (preShadow, retrograde, cazimi, postShadow or direct), with the sign, the cycle's five moments (pre-shadow, station retrograde, cazimi, station direct, post-shadow end) and days left to the next transition. Ti…

  • next_mercury_retrograde

    Returns the next Mercury retrograde after a date (or the one in progress, until it stations direct) with its sign, pre-shadow, station retrograde, cazimi, station direct and post-shadow end. Times are UTC, to the minute, from the ephemeris (JPL DE421, 2025–2030). This is astrono…

  • next_mercury_cazimi

    Returns the next Mercury cazimi (exact Sun–Mercury conjunction during a retrograde) after a date, with the UTC minute, the degree and 17′ window when known, and the previous cazimi. A cazimi within 12 hours of the date counts as today's and is returned as the previous one. Times…

  • mercury_retrograde_dates

    Lists every Mercury retrograde period that falls in or overlaps a year from 2025 to 2030, with sign, pre-shadow, station retrograde, cazimi, station direct and post-shadow end. Times are UTC, to the minute, from the ephemeris (JPL DE421, 2025–2030). This is astronomical timing,…

  • retrograde_planets_today

    Use for "which planets are retrograde" questions. For Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto on a date, returns the phase (preShadow, retrograde, postShadow or direct), the sign, the current or next cycle's moments, cazimi-day (Mercury, Venus) and oppos…

  • is_planet_retrograde

    Says whether Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune or Pluto is retrograde on a date and which phase it is in, with the sign, pre-shadow, station retrograde, cazimi (Mercury, Venus) or opposition (Mars through Pluto), station direct, post-shadow end and days left…

  • planet_retrograde_dates

    Lists every retrograde period of Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune or Pluto that falls in or overlaps a year from 2025 to 2030 (a year with none says so and names the next one), with sign, shadows, cazimi or opposition, and stations. Times are UTC, to the mi…

  • next_planet_retrograde

    Returns the next retrograde of Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune or Pluto after a date (or the one in progress, until it stations direct), with sign, shadows, cazimi or opposition, and stations. Times are UTC, to the minute, from the ephemeris (JPL DE421, 20…

  • ephemeris_range

    Every retrograde-cycle moment of Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune or Pluto between two dates: pre-shadow start, station retrograde, cazimi or opposition, station direct and post-shadow end, each to the UTC minute with the zodiacal degree, as a sorted event…

  • get_daily_inspiration

    The day's inspiration from the Cazimi app and cazimi.live: two short true stories tied to the calendar date (a person born or died, or an event, on this day in history), one verbatim quote from a public-domain classic (Marcus Aurelius, Epictetus, Seneca, Laozi, Tagore, Emerson,…

  • moon_now

    The Moon at a moment: phase name and angle, illumination, age, lunar day (30 per lunation by 12° of elongation, with its start time), sign and degree, next sign ingress, whether it is void of course and until when, the next four phases to the minute, and moonrise/moonset when la…

  • moon_calendar

    A whole month of the Moon: every phase with its UTC minute, every sign ingress, every void-of-course period with its last aspect, and for each day the phase, illumination, lunar day and position at noon UTC. Computed live from the ephemeris (astronomy-engine, about 1′), tropical…

  • void_of_course

    Every void-of-course Moon period between two dates (up to 62 days): start (the Moon's last exact Ptolemaic aspect to the Sun or a planet in its sign), end (entry into the next sign), length in hours, the last aspect and the signs. Computed live from the ephemeris (astronomy-engi…

  • planet_positions

    Geocentric tropical longitude, sign and degree, ecliptic latitude, daily speed and retrograde flag of the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and the mean North Node at a moment, 1900–2100. Computed live from the ephemeris (astronomy-engine,…

  • natal_chart

    Chart geometry for a birth or event moment at a place: planets and North Node with sign, degree, speed, retrograde flag and house; Ascendant and Midheaven; twelve house cusps (Placidus by default, or whole-sign or equal; whole-sign above 66° latitude); and the Ptolemaic aspects…
