The void calendar
Void-of-course Moon, August 2027.
Computed in America/New York (Eastern Time); every time prints its UTC offset.
A void begins at the Moon’s last exact major aspect in a sign and ends when it enters the next. Orrery uses a modern definition and applies a score penalty to starts during these intervals. This is an astrological rule, not a prediction of an outcome. Each row shows the calculated times and the preceding aspect.

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.
