- [What's my rising sign? How to find it, and why it moves](https://cosmicmeridian.com/what-is-my-rising-sign/) — What a rising sign is, why it changes about every two hours, why the birth time and place both matter — and a private rising-sign form right on this page.
- [Zodiac dates 2026 and 2027: when each sign begins](https://cosmicmeridian.com/zodiac-dates/) — The exact instant the Sun enters each sign, September 2026 to December 2027, in UTC and on your own clock — why lists disagree, and what a cusp really is.
- [Saturn return: the 29-year cycle, and your own dates](https://cosmicmeridian.com/saturn-return/) — What a Saturn return is — Saturn back at its natal degree about every 29.46 years — and your own three dates, found in your browser from a birth date.
- [Learn astrology, plainly: three guides and a glossary](https://cosmicmeridian.com/learn/) — Three plain guides — the rising sign, zodiac dates, the Saturn return — and a twenty-term glossary of the words this site's charts and sky pages use.
- [Ascendant (rising sign): what it means in astrology](https://cosmicmeridian.com/learn/ascendant/) — The sign climbing the eastern horizon at your exact birth minute and place.
- [House (whole-sign): what it means in astrology](https://cosmicmeridian.com/learn/house/) — One of twelve life-areas of a chart, counted the whole-sign way here: from the Ascendant in a birth chart, from the Sun sign on the daily horoscope pages.
- [Cusp: what it means in astrology](https://cosmicmeridian.com/learn/cusp/) — The everyday word for the day a sign changes over — the boundary itself, not a blend of the two signs on either side of it.
- [Aspect: what it means in astrology](https://cosmicmeridian.com/learn/aspect/) — An angle between two points in a chart, measured in degrees, close enough to a round number to count as a real contact.
- [Conjunction: what it means in astrology](https://cosmicmeridian.com/learn/conjunction/) — Two points sitting at, or close to, the same degree — the tightest aspect, read as a blending of whatever the two points represent.
- [Sextile: what it means in astrology](https://cosmicmeridian.com/learn/sextile/) — A friendly 60-degree angle between two points — enough distance to be its own thing, close enough to work together without much friction.
- [Square: what it means in astrology](https://cosmicmeridian.com/learn/square/) — A tense 90-degree angle between two points — a friction that tends to press for a decision rather than let things sit.
- [Trine: what it means in astrology](https://cosmicmeridian.com/learn/trine/) — An easy 120-degree angle between two points — the most flowing aspect, often read as an ease or a talent that arrived without effort.
- [Opposition: what it means in astrology](https://cosmicmeridian.com/learn/opposition/) — A 180-degree angle between two points, directly across the wheel — two things facing each other, needing balance rather than a winner.
- [Orb: what it means in astrology](https://cosmicmeridian.com/learn/orb/) — How many degrees an aspect can miss its exact angle by and still count — a margin, not a strict, all-or-nothing cutoff.
- [Ecliptic: what it means in astrology](https://cosmicmeridian.com/learn/ecliptic/) — The Sun's apparent yearly path across the sky — the line the entire zodiac is measured along, in degrees, all the way around back to where it started.
- [Ephemeris: what it means in astrology](https://cosmicmeridian.com/learn/ephemeris/) — A table, or an engine, giving the exact position of the Sun, Moon and planets for any date and time you ask for.
- [Ingress: what it means in astrology](https://cosmicmeridian.com/learn/ingress/) — The exact moment a planet crosses from one sign into the next — an entrance, not a whole day, timed to the minute.
- [Lunation: what it means in astrology](https://cosmicmeridian.com/learn/lunation/) — A general word for a phase point in the Moon's monthly cycle — most often used for the new moon and the full moon.
- [New moon: what it means in astrology](https://cosmicmeridian.com/learn/new-moon/) — The point in the lunar month when the Sun and Moon meet exactly — the quiet, dark start of the roughly month-long cycle.
- [Full moon: what it means in astrology](https://cosmicmeridian.com/learn/full-moon/) — The moment each month the Moon sits exactly opposite the Sun — the bright peak of the lunar cycle, on the far side from the new moon.
- [Retrograde: what it means in astrology](https://cosmicmeridian.com/learn/retrograde/) — When a planet appears, from Earth, to move backward through the zodiac for a while — an optical effect of two orbits at different speeds.
- [Station: what it means in astrology](https://cosmicmeridian.com/learn/station/) — The moment a planet's apparent motion pauses and reverses direction — the turning point at either end of a retrograde stretch.
- [Shadow period: what it means in astrology](https://cosmicmeridian.com/learn/shadow-period/) — The stretch before and after a retrograde when a planet revisits degrees it will cross again, or has already crossed, while retrograde.
- [Void-of-course Moon: what it means in astrology](https://cosmicmeridian.com/learn/void-of-course-moon/) — The stretch after the Moon's last exact aspect in a sign until it enters the next one — a pause between one thing and the next.
