The void calendar
Void-of-course Moon, December 2025.
Computed in America/New York (Eastern Time); every time prints its UTC offset.
A void begins at the Moon’s last exact aspect in a sign and ends when it enters the next. The classical read — the one Orrery scores with — is that what starts inside a void tends not to stick: finish things, file things, rest. Don’t launch them. Each row below is computed to the minute and names the aspect that began it.

What a void means for real decisions
Orrery weighs the void most heavily for commitments: see the month pages for signing a contract and launching, where each void appears inside the day it drags on. The full rulebook — including which void convention Orrery follows — is in Method.
