13 voids, 15% void
End of summer, start of the school year, and a calendar with room to work.
September is back-to-school, back-to-work, back-to-the-spreadsheet. Its void calendar is cooperative: thirteen windows and a modest total, with most periods under half a day.
The longest arrives at the very end. The Moon sextiles Mars in Virgo and then stays void for most of a day before entering Libra, where it meets the Sun for the New Moon. So the Libra New Moon, popular for partnerships and contracts, comes right after a quiet stretch. Prepare during the void, sign once the Moon is in Libra.
The Full Moon in Pisces mid-month is a soft, emotional one, good for finishing creative work or easing off after a busy start to the term. A short Cancer void late in the month lasts only about three hours, small enough to schedule around with a single shift.
11th of 12
September 2027, counted
13 windows, 105 h. 11th of 12 by hours; 25% under a 2027 month's mean; none past 24 h. Weekend starts (UTC): 5. Weekday 13:00 to 22:00 UTC starts: 3.
1 of 2 September lunations (the Full Moon at 22°53′ Pisces on Wed Sep 15 · 23:03 UTC, the New Moon at 6°43′ Libra on Thu Sep 30 · 02:36 UTC) lands inside a void.
The sky behind it
September last aspects: Saturn 7, Mercury 2, Sun 2, Venus 1, Mars 1. Method.
5 planets close voids
A Full Moon that starts a void
September's Full Moon falls at 23:03 UTC on September 15, at 22°53′ Pisces, and the Moon's opposition to the Sun is its last aspect in that sign. So the void begins at the exact minute of the Full Moon and runs almost fourteen hours, until the Moon enters Aries on the 16th.
Saturn closes seven of September's thirteen voids, matching August. Most of these are short and evenly spaced: Libra on the 4th, Sagittarius on the 8th, Capricorn on the 11th, Aquarius on the 13th, Aries on the 18th, Gemini on the 23rd and Leo on the 27th. None of the seven runs past seven hours.
The Libra void on September 4 is another single-aspect sign: the Moon's opposition to Saturn is its only Ptolemaic contact there. Only three voids pass twelve hours, and the longest, about twenty hours in Virgo at the end of the month, begins after a sextile to Mars. Four voids start on a Saturday (UTC).

September: when to wait, when to go
Try this today
- Draft the contract during the Virgo void, sign it after.
- Start the new routine in the first fortnight.
- Use the Pisces Full Moon for a gentle evening off.
Front-load September's starts, since nothing in the first three weeks runs much past 19 hours. Use the final Virgo void to prep the Libra New Moon plans, then act once the Moon has changed sign.
Thirteen voids, and only the Sagittarius window on September 5 to 6, the Pisces one after the Full Moon, and the Virgo stretch from the 28th to the 29th run past twelve hours. The rest are short enough to plan a meeting before or after. If you are signing something at the Libra New Moon on September 30 at 02:36 UTC, the Moon has already left that Virgo void about eleven hours earlier.

Quick answers
Is September 2027 good for signing a contract?
The Libra New Moon at month's end is a traditional favourite. It follows a long Virgo void, so sign after the Moon has entered Libra, not during the pause.
How many void of course Moons are there in September 2027?
Thirteen, all listed with start and end times in the table on this page.
Why does a void begin right at September's Pisces Full Moon?
Because the opposition to the Sun at 23:03 UTC on September 15 is the last aspect the Moon makes in Pisces. Nothing else follows it in that sign, so the window opens on the minute and lasts almost fourteen hours, until Aries begins at 12:56 UTC on the 16th.
