how long will the blood moon last

The total phase of a blood moon, or total lunar eclipse, typically lasts between 30 and 100 minutes. For the specific blood moon event on September 7-8, 2025, the totality phase is expected to last approximately 82 minutes. This total phase is when the moon is completely in Earth's umbra, taking on the characteristic reddish color, and it is followed by partial phases where the moon gradually moves out of the shadow. Overall, the entire eclipse event, including penumbral and partial phases, can span several hours, but the deepest red "blood moon" appearance lasts around an hour to an hour and a half depending on the eclipse specifics.
