An astrology calendar is a schedule of the sky: when planets form exact angles to each other, when they move from sign to sign, when the Moon changes phase and when a planet turns retrograde. It shows you the exact positions of the planets and the events that astrological interpretation is built on. This calendar covers 1900–2050.

Calendar by year
A year gives you the big picture: eclipses, retrogrades, sign changes, new and full moons. A month gives you the day-by-day detail.

How This Calendar Is Calculated
If you are comparing dates with another calendar and see a gap of a few hours, check the time zone: the default here is Eastern Time. You can switch it in the panel above the tables.
Frequently Asked Questions
What is an astrology calendar, exactly?
It is a schedule of what happens in the sky: when planets form exact angles to each other (aspects), when they move from sign to sign, when the Moon goes through its phases, and when a planet turns retrograde. A horoscope is somebody's interpretation. An astrology calendar is the raw data those interpretations are built on.
Why don't your times match another site?
Usually it is the time zone. Many astrology sites publish in Universal Time (UT), and we show Eastern Time by default, which is 4 or 5 hours behind it. That alone can move an event to the neighbouring day. The time zone switch in the panel at the top settles it in a second.
Does an aspect work exactly at the minute you list?
That is the minute it goes exact. The effect is felt wider – usually a day before and a day after, and for slow planets, for weeks. The exact time tells you where the peak is; it is not something to set an alarm for.
What do you do with a void of course Moon?
Don't start anything that matters in that window: signings, purchases, introductions, first meetings. It is excellent time for routine, for clearing the backlog, for tidying up and for rest. The windows run from a few minutes to a full day – see the table above.
Is a retrograde planet a bad thing?
No. Retrograde motion is an optical effect: from Earth the planet appears to move backward. Astrologically it is a change of mode: the planet's theme works inward and backward instead of forward. The only bad move is pushing hard at something that has no tailwind right now.
Where do these numbers come from?
We calculate the dates from the NASA JPL ephemerides JPL DE440. There is more about the sources and the checks on the methodology page.
