Void-of-course Moon times, 16 October 2026 to 30 October 2026
The Moon's next void period begins 18 October 2026 at 17:12 BST, after its square to Sun, and ends when it enters Aquarius at 02:39 BST. Every period below is computed from the real positions of the Moon and the planets, in UK local time.

Each row is a day from midnight to midnight. The filled stretches are the void periods in the table, drawn from the same computed instants.
What is actually happening
The Moon moves through the twelve signs in about twenty-seven days, so it changes sign roughly every two and a half days. On its way across each sign it makes aspects — conjunctions, sextiles, squares, trines and oppositions — to the Sun and the five classical planets, each exact at a moment that can be computed. Sooner or later it makes the last one it will make in that sign. The stretch from that last aspect to the moment it enters the next sign is what the old term void of course names: the Moon is between appointments.
That is all it is — geometry, with a time on it. The traditional rule of practice was that nothing begun in those hours comes to much; the modern version is quieter, and it is the one we hold to: a poor time to start something, a fine time to finish something. We claim nothing beyond that, and the number the app gives you is capped, not zeroed, while it lasts.
The times here are the exact ones. "Void this afternoon" is not an answer anyone can plan around; 17:12 BST is.
How often, and for how long
Over the next two months the Moon is void about 17% of the time — measured from the periods themselves, not quoted. In the fortnight above the periods average 7 h 29 min, and the longest runs 16 h 22 min. Most are a few hours; a long one can take most of a day, because the last aspect happened to fall early in the sign.
It follows the Moon's own clock and nothing else. There is no bad month for it and no way to avoid it; there is only knowing when it is.
Why we compute this
Eondra is a daily timing brief. The middle part of its number — the Moon today, out of 25 — is capped at 10 while the Moon is void, and the brief says so in plain words rather than as an omen. How the number is built shows the whole of it; Mercury retrograde dates come from the same engine.
