Ephemeris
Look up the daily position of every planet in the zodiac — Sun through Pluto — day by day, in a clean table you can step through a week, a month or a full quarter at a time.
An ephemeris is a table of where the planets are on any given day — the backbone of astrology and astronomy for centuries. For each date it records the position of the Sun, Moon and planets by zodiac sign and degree, so you can see at a glance that the Sun is at 14° Cancer or that Mars has moved into Leo. Astrologers reach for it constantly: to time transits, to check a planet’s speed, or to see when a body changes sign.
Reading an ephemeris tells you not just where a planet is but how it is moving — whether it is racing ahead, slowing to a standstill, or turning retrograde. Fast movers like the Moon shift a full sign every couple of days; slow outer planets like Neptune and Pluto barely budge across a month. Watching those speeds is how you spot the moments that matter: stations, sign ingresses and the tight aspects between planets.
GemZen's Ephemeris renders any span from a week to ninety days as a scrollable table, one row per day, with each planet’s sign and degree laid out in columns. Pick a start date, choose how many days to show, and step month by month to trace a planet across the year — a reference you can keep open beside a chart or a forecast.
How it works in GemZen

Set a start date
Choose the day you want the table to begin, or step forward and back a month at a time to land on the period you care about.

Common questions
Is the ephemeris free?
Yes — a free GemZen account lets you generate daily positions for any date range. Longer spans and pairing the ephemeris with saved charts and forecasts come with paid plans.
What does an ephemeris show?
For each day it lists where the Sun, Moon and planets sit in the zodiac by sign and degree, so you can see their positions, speed and when they change sign.
How far ahead can I look?
Choose spans from 7 up to 90 days at a time, and step month by month to trace a planet across a whole year or beyond.
Is the ephemeris astrological advice?
It is precise astronomical data presented for study and reflection. Any interpretation you draw from it is for insight and entertainment — not medical, legal or financial advice.
