ORRERYBest day to launch a business

Launch / publish — December 2025

The best days to launch a business in December 2025.

Computed in America/New York (Eastern Time); every interval prints its UTC offset. A different timezone shifts the day boundaries — the sky doesn’t change, but the local days it lands in can.

This month has passed. The current month is launch a business in September 2026.

You’ve got the launch on the calendar. Here is December 2025, scored for launching: every hour rated on the Moon void-of-course, Mercury retrograde, the Moon’s phase, and its next applying aspect for this decision — then averaged per day. Fifty is a flat sky; every point above it is computed help, every point below is drag.

The month’s best stretch opens Wed, Dec 24, 9:00 PM EST and holds until Fri, Dec 26, 1:00 PM EST, scoring 76.

Amber rows below are the days that stretch touches. Scores compare moments; they do not promise results.

How to read this

Void-of-course— after the Moon’s last exact aspect in a sign, before it enters the next. The classical read: finish things; don’t start them. Exact times are in the void calendar for December 2025. Mercury retrograde — the traditional caution for messages, deals, and signatures; station times to the second are in the retrograde dates. Waxing / waning — growing favors starts, thinning favors finishing. The applying aspect— the Moon’s next exact contact with this decision’s planet, easy angles helping, hard angles dragging. The full rulebook — which conventions Orrery follows and which it refuses — is in Method.
