When is the best day to launch a business in December 2023?

The month's best stretch opens Wed, Dec 13, 11:00 AM EST and holds until Wed, Dec 13, 9:00 PM EST, scoring 68 against a base of 50, computed in America/New York (Eastern Time). Scores compare moments; they do not promise results.

How are these scores computed?

Every hour is rated on four factors — the Moon void-of-course, Mercury retrograde, the Moon's phase, and its next applying aspect for this kind of decision — then averaged per local day under a versioned config. These pages stop there, because a page has no location; the app adds a fifth factor, the Moon's house, once it knows where you are, which is what lets it name an hour rather than a day. Fifty is a flat sky; every point above it is computed help, every point below is drag.

What does void-of-course mean?

The Moon has made its last exact aspect in a sign and is coasting until it enters the next. The classical read: finish things, don't start them.

Launch / publish — December 2023

The best days to launch a business in December 2023.

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.

You’ve got the launch on the calendar. Here is December 2023, 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 13, 11:00 AM EST and holds until Wed, Dec 13, 9:00 PM EST, scoring 68.

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 2023. 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.
