Astrology calendar by year

The full run of a whole year, month by month — every event with its date, time and sign, plus what it means in plain language.

What is in the astrology calendar — and why

New moon & full moon
The Moon needs about 29.5 days for one cycle. The new moon reads as a starting point, the full moon as the moment something becomes visible — which is why so many rituals attach to these two points.
Eclipses
Two to four times a year a new or full moon falls close enough to the lunar nodes to become an eclipse. They read as an accelerated version of the underlying phase and arrive in series spanning roughly 18 months.
Retrogrades
No planet actually moves backwards — it only looks that way from Earth as we overtake it. Astrologically the phase reads as a time of repetition: reviewing, correcting and revising rather than starting fresh.
Sign changes
When a planet changes zodiac sign, the tone of its theme changes with it. For fast planets that lasts days; for Saturn, Uranus, Neptune and Pluto it lasts years, so those ingresses mark whole chapters.
Exact aspects
An aspect is the angle between two planets. The calendar marks the moment it becomes exact — the peak of a configuration that is already noticeable before and after.

Astrology calendar — common questions

What does an astrology calendar show?
Every moment the sky measurably shifts: new moons and full moons, eclipses, the start and end of each retrograde phase, every planetary sign change, and every exact aspect between two planets — each one dated and timed to the minute.
Which timezone are the times in?
Yours. The calendar picks up your timezone when it loads and converts every time; you can pick a different one in the top right. That matters more than it sounds: a full moon at 00:45 in Berlin is the evening before in London.
Is the astrology calendar free?
Yes, in full and without an account. It is computed with the Swiss Ephemeris engine — the same basis professional astrology software runs on.
Can I get these dates into Google or Apple Calendar?
Yes. The same calendar is available as an iCal file (.ics) to import or subscribe to, so moons, retrogrades and eclipses sit right next to your own appointments.
What do the colours and dots mean?
The beige-filled entries are the high-impact ones — eclipses, retrogrades, full and new moons. The small dot shows the tone: green for supportive, amber for friction, grey for neutral. They are orientation points, not verdicts about your day.
