Full Moon October 2025: When To See The 'Harvest Supermoon' Rise

The harvest moon is the ninth of 12 full moons in 2025. A solar year is 365.24 days, while a lunar year is around 354.37 days, so sometimes there are 13 full moons in one calendar (solar) year -- as in 2023 and next in 2028. Of the 12 full moons in 2025, three will be "supermoons" -- of which the harvest moon is the first -- with two "blood moon" total lunar eclipses (the first happened on March 13-14 and the second on Sept. 7-8). The next full moon will be the beaver moon, the year's biggest "supermoon" (and the biggest since 2019), on Wednesday, Nov. 5, 2025.
