  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

astro_calendar

The events of a month (2020–2035): new and full moons and quarters with their signs, the Sun and planets entering signs, retrograde stations and all retrograde periods touching the month, solar and lunar eclipses with their visibility from Warsaw; optionally every Moon sign change. Times in a time zone (Polish time by default).

Discovered
birth_chart

Computes a natal (birth) chart from the date, local clock time and place of birth: the Sun, Moon, planets, lunar node and Lilith in the signs of the tropical zodiac and in the houses, the ascendant and midheaven, house cusps (Placidus or whole sign), aspects with orbs, the phase of the Moon, the Chinese year sign and the four pillars (BaZi), and how close the ascendant, houses and signs are to changing with the hour. Without a time it gives what does not depend on the hour. The time zone and summer time of the place are applied from the IANA history. Calculations only, no interpretation; the link opens the full result on the site.

Discovered
chinese_year

The Chinese zodiac of a year (1901–2100): animal, element, yin or yang, the sexagenary name, the dates of Chinese New Year and of the year's last day, and Lichun. With a date of birth instead, which Chinese year and sign it falls in (January and February births often belong to the year before) and the year of the four pillars.

Discovered
find_place

Coordinates and IANA time zone of a town or city: all places in Poland and world cities over 15 000 people, Polish names first (Londyn and London both work). Use it to check which place birth_chart or sky_at would take, or to pick one of several of the same name and pass its lat, lon and tz.

Discovered
planet_returns

When Saturn (about at 29, 59 and 88) and Jupiter (about every 12 years) come back to their places of birth: each return with its dates and the age, three crossings when retrograde motion takes the planet back over the place.

Discovered
sign_dates

When the Sun enters each zodiac sign in a given year (1900–2100), to the minute, in a time zone (Polish time by default). With a sign, also its usual first and last day and the earliest and latest entry across 1900–2100. For "what is my sign" when someone is born near the edge of two signs.

Discovered
sky_at

Where the Sun, Moon and planets are in the zodiac at a moment (now when no date is given): signs and degrees, which planets are retrograde, aspects between them, the Moon's sign, phase and next sign change, the next new and full moon. With a place it adds the ascendant, midheaven and houses. For questions like "what sign is the Moon in today" or "is Mercury retrograde now".

Discovered
sky_card

Makes a printable card of the sky on a day that matters - a birthday, the birth of a child, a wedding or any day - at a place: the link opens the sky map over that place (at the given hour, or 22:00) with a title, a line, the Moon's phase, sunrise and sunset, the planets, the signs and a QR code of the card, ready to print on A4, A3 or as an A6 greeting card. The answer also lists those facts, eclipses within 15 days, the meteor showers active that night and the NASA picture of the day of that date. Use it when someone wants a gift or keepsake of the night sky on a date.

Discovered
solar_return

The moment the Sun comes back to its place of birth in a year (this year by default), to the minute, and the chart of that moment for the place of the birthday (the place of birth by default): planets, ascendant and houses, and the returns of the next years.

Discovered
synastry

Compares two birth charts: the aspects between the planets (and ascendant and midheaven when known) of the two people, the most exact first, and each person's planets in the other's houses. Each person is an object with date, time (optional), place (or lat, lon, tz) and name (optional). Calculations only, no reading of the relationship; the link opens the double chart on the site.

Discovered
transits

The planets of a day (today by default) against a birth chart: their houses in it, their aspects to the points of birth, and the exact transits of Jupiter, Saturn, Uranus, Neptune and Pluto to it for twelve months. Calculations only, no forecast.

Discovered
vedic_chart

A birth chart in the sidereal zodiac (Lahiri ayanamsa): the lagna, the nine grahas in their rashis with nakshatras and padas, whole-sign houses, navamsa (D9) signs and the Vimshottari periods with the current mahadasha and antardasha. Without the hour no lagna or houses. Calculations only.
