What an ephemeris calculator shows
An ephemeris is a table of where the Sun, Moon, and planets are on each day. Astrologers use it to see when a transit becomes exact, when a planet turns retrograde, and when it changes sign.
How to read one row
This is the November 7, 2026 row from the web table above, calculated for midnight in New York. Each column is one planet. Each cell gives its degree, its minutes of arc, and its sign.
Read down a column to follow one planet through the month. A degree in gold means that planet entered a new sign that day.
| Column | Value | What it means |
|---|---|---|
| Day | 7 Sa | Day of the month and weekday. Today's row is highlighted. |
| ST | 08:05:41 | Sidereal time, the star-based clock you need to work out house cusps by hand. |
| Sun | 14°48′ Sco | 14 degrees 48 minutes of Scorpio. |
| Moon | 20°39′ Lib | The fastest body. It changes sign about every two and a half days. |
| Mercury | 08°56′ Sco Rx | Rx means retrograde: Mercury appears to move backward through Scorpio. |
| Venus | 23°49′ Lib Rx | Venus is retrograde in Libra on the same day. |
| Mars | 21°41′ Leo | Moving forward through Leo. |
The Monthly Ephemeris on iPhone.
Open the Explore tab and tap Monthly Ephemeris. The table loads for the current month, one row per day.
- One row per day for the whole month, with the weekday beside each date
- Sun to Saturn by default, plus Uranus, Neptune, Pluto, Lilith, Chiron, and the true Nodes
- Rx for retrograde and S for a station
- Gold highlighting on the day a planet or the Moon enters a new sign
- A sidereal time column for working out house cusps by hand
- Arrows to move to any earlier or later month
Positions are calculated with the Swiss Ephemeris through FreeAstroAPI, using the tropical zodiac.

Ephemeris questions
What is an ephemeris calculator?
An ephemeris calculator lists where the Sun, Moon, and planets are on each day, by zodiac sign and degree. It also shows when a planet turns retrograde, stations, or changes sign. Astrologers use it to time transits, find returns, and look up planet positions for any date.
Is the AstroLingo ephemeris really free?
Yes. The web ephemeris table needs no account or birth profile. In the app, the Monthly Ephemeris, the Annual Lunations Table, and the current sky chart have no paywall. AstroLingo Plus is optional and unlocks the deeper lesson path and some written interpretations.
Does it work on Android?
Yes. AstroLingo is on Google Play and the App Store, and the Monthly Ephemeris is in the Explore tab on both. You can also open the ephemeris table in any browser.
Is the AstroLingo ephemeris tropical or sidereal?
It uses the tropical zodiac. For sidereal positions, Astrodienst, Astro-Seek, and iPhemeris all offer sidereal ephemerides.
Which planets and points can I show?
The Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn appear by default. You can add Uranus, Neptune, Pluto, Lilith, Chiron, and the true North and South Nodes.
How accurate are the positions?
Positions come from the Swiss Ephemeris through FreeAstroAPI and are shown to the arcminute. The Swiss Ephemeris is the engine behind Astrodienst and many professional astrology programs.
Can I choose the time of day or look up other months?
Yes. The web table lets you pick a city and a daily time, and every version moves backward or forward one month at a time.
