New Moon in Leo — August 12, 2026
Exact at 1:37 PM ET · 20° Leo · Total solar eclipse
This one is also an eclipse — total, at 20° Leo. A solar eclipse is a new moon that crosses directly in front of the Sun, close enough to the lunar nodes for the shadow to reach Earth. Astrologically an eclipse is read as this moon on a longer fuse: weeks rather than days, and more often a door that closes behind you than one you can walk back through.
Be seen doing it
Leo new moons reward the thing you would do if you were not worried about looking foolish. Publish, perform, apply, put your name on it. The point is not attention for its own sake — it is that Leo intentions require an audience to become real, and the private version of this goal has already had its chance.

Full Moon in Pisces — August 28, 2026
Exact at 12:19 AM ET · 4° Pisces · Partial lunar eclipse
This one is also an eclipse — partial, at 4° Pisces. A lunar eclipse is a full moon that passes through Earth's own shadow, which is why it reddens rather than dims. Astrologically an eclipse is read as this moon on a longer fuse: weeks rather than days, and more often a door that closes behind you than one you can walk back through.
The line you stopped holding
Pisces full moons show where you have dissolved into someone else's situation — the favour that became a role, the empathy that became responsibility. Exhaustion arrives before the explanation does. What is asked is not that you care less but that you locate, specifically, the point at which your involvement stopped helping and started substituting.

How these dates were calculated
A new moon is the instant the Moon and Sun share the same ecliptic longitude; a full moon is the instant they sit exactly opposite. Both are single moments rather than nights, and both are computed here directly from the Swiss Ephemeris — the engine professional astrology software runs on — then localized to US Eastern Time. Nothing on this page is copied from another calendar.
The degree matters more than the phase. A full moon at 4° Pisces activates whatever sits near that degree in your own chart, which is why one lunation flattens one person and passes another entirely. To find out which of your placements August 2026's moons touch, cast your free natal chart and compare the degrees, then read your monthly horoscope for the wider context.
That was the sky. This is your sky.
