When the Moon crosses Earth's shadow at the center of the umbra, the entire eclipse process, including the partial phases before and after totality, can last up to 6 hours. This duration encompasses the time from when the Moon first enters the penumbral shadow of the Earth, moves into the umbra for the total phase, and then exits back through the penumbral shadow.
