What we track
Retrogrades. When a planet appears to move backward through the zodiac from Earth's perspective, astrologers call it retrograde. Mercury retrograde is the most well known, but every planet except the Sun and Moon has retrograde periods. The calendar marks the start and end dates of each retrograde so you can see what is active at any given time.
Eclipses. Solar and lunar eclipses occur in pairs roughly every six months, falling along a specific zodiac axis. Eclipse seasons are traditionally considered periods of significant change, as they activate the lunar nodes. The calendar lists each eclipse by type, date and the sign it falls in.
Sign ingresses. An ingress is the moment a planet moves from one zodiac sign into the next. The Sun changes signs roughly every 30 days, marking the familiar shift from one "season" to the next. Slower planets change signs far less often, and those shifts tend to mark broader cultural and generational themes. The calendar tracks ingresses for all major planets.
Other notable transits. Certain planetary aspects, such as outer-planet conjunctions or significant station points, are worth noting because they set the tone for extended periods. The calendar highlights these when they are astrologically noteworthy.
How to use the calendar
The astrology calendar is a reference tool, not a prediction engine. Use it to understand the astrological weather: what energies are active, what themes are emphasized and when shifts are happening. If you know your birth chart, you can compare the calendar transits to your natal placements to see which events might be personally relevant.
The calendar does not tell you what will happen. It tells you what is happening in the sky, described in astrological terms. What you do with that information is up to you.
