Our next full moon will occur on Oct. 6, and it will be a somewhat special one for those living in the Northern Hemisphere in that it will also carry the title of "Harvest Moon." The moon officially turns full when it reaches that spot in the sky opposite (180 degrees) to the sun in the sky and this moment will occur on Tuesday, Oct. 7 at 03:48 GMT (which corresponds to 11:48 p.m. EDT on Oct.6, or 8:48 p.m. PDT).
But it also turns out that this full moon is the one that comes closest on the calendar to the September equinox. In 2025, this circumstance comes later than usual, into the month of October, as opposed to the more traditional month of September. Full moon in September came on Sept. 7 and occurred 15.006 days prior to the autumnal equinox. The full moon of Oct. 6 occurs 14.395 days after the equinox, or 14 hours and 39 minutes nearer to the equinox than September's full moon.
