September 2027 New Moon falls on Thursday, September 30, 2027, which is 342 sleeps away. A sleep count is the number of nights still to come rather than the number of days, which is why it is the version adults reach for when the person asking is a child — and why it stays intuitive long after the day count stops meaning much.

How a sleep count works
The convention: one sleep means one night still to go. On the morning before, the answer is one. On the morning of the day itself, it is zero — you have run out of nights to sleep through. Because it tracks nights rather than 24-hour periods, the figure can read one higher than the day count for an event that lands in the morning.
About September 2027 New Moon
The September 2027 new moon falls at 02:37 UTC on September 30, 2027, at 6°43' Libra. The Moon sits between Earth and Sun, so its dark side faces us: no Moon visible for about a day on either side.
A new moon in Libra is the traditional planting moment of the month — the sky's blank page. Anything begun in the days around it shares the sign's flavor, and the intentions you set now come to full light at the Libra full moon six months later.
