What time the 2024 solar eclipse starts, reaches peak totality and ends today
The 2024 solar eclipse will be visible across North America today. As the moon’s position between the Earth and sun casts a shadow on North America, that shadow, or umbra, will travel along the surface from west to east at more than 1,500 miles per hour along the path of totality.
That means the eclipse will start, peak and end at different times — as will the moments of total darkness along the path of totality — and the best time to view the eclipse depends on where you are located. Some places along the path will have more totality time than others.

The total solar eclipse will emerge over the South Pacific Ocean before the shadow falls across North America, beginning in parts of Mexico. The path of totality, where onlookers can witness the moon fully blocking the sun (through eclipse viewing glasses for safety), is expected to first make landfall near the city of Mazatlán around 9:51 a.m. MT.
Canadian mainland at 3:13 p.m. ET.
Although the experience won’t be exactly the same, viewers in all the contiguous U.S. states outside the path of totality will still be able to see a partial eclipse. Some places will see most of the sun blocked by the moon, including Washington, D.C., where the partial eclipse will start at 2:04 p.m. ET.
New York City will also see a substantial partial eclipse, beginning at 2:10 p.m. ET.
In Chicago, viewers can start viewing the partial eclipse at 12:51 p.m. CT.
In Detroit, viewers will be able to enjoy a near-total eclipse beginning at 1:58 p.m. ET, and in Boston it will begin at 2:16 p.m. ET.
The below table by NASA shows when the eclipse will start, peak and end in 13 cities along the eclipse’s path.
What time will the solar eclipse reach peak totality?
Millions more people will have the chance to witness the total solar eclipse this year than during the last total solar eclipse, which was visible from the U.S. in 2017.
The eclipse’s peak will mean something different for cities within the path of totality and for those outside. Within the path of totality, darkness will fall for a few minutes. The longest will last more than 4 minutes, but most places will see between 3.5 and 4 minutes of totality. In cities experiencing a partial eclipse, a percentage of the sun will be obscured for more than two hours.
Mazatlán is set to experience totality at 11:07 am PT. Dallas will be able to see the moon fully cover the sun at 1:40 p.m. CT. Little Rock will start to see the full eclipse at 1:51 p.m. CT, Cleveland at 3:13 p.m. ET and Buffalo at 3:18 p.m. ET. Totality will reach Burlington at 3:26 p.m. ET before moving into the remaining states and reaching Canada around 4:25 p.m.
Outside the path of totality, 87.4% of the sun will be eclipsed in Washington, D.C. at 3:20 p.m. ET, and Chicago will have maximum coverage of 93.9% at 2:07 p.m. CT. New York City is much closer to the path of totality this year than it was in 2017; it will see 89.6% coverage at 3:25 p.m. EDT.
Detroit is another city that will encounter a near-total eclipse, with 99.2% maximum coverage at 3:14 p.m. ET. Boston will see 92.4% coverage at 3:29 p.m. ET.
What time will the solar eclipse end?
The eclipse will leave continental North America from Newfoundland, Canada, at 5:16 p.m. NT, according to NASA.
At the beginning of the path of totality in Mazatlán, the eclipse will be over by 12:32 p.m. PT, and it will leave Dallas at 3:02 p.m. CT. The eclipse will end in Little Rock at 3:11 p.m. CT, Cleveland at 4:29 p.m. CDT and Buffalo at 4:32 p.m. ET. Burlington won’t be far behind, with the eclipse concluding at 4:37 p.m. ET.
Meanwhile, the viewing will end in Chicago at 3:21 p.m. CT, Washington, D.C. at 4:32 p.m. ET, and New York City at 4:36 p.m. ET.
In Detroit, the partial eclipse will disappear at 4:27 p.m. ET, and in Boston, it will be over at 4:39 p.m. ET.
How long will the eclipse last in total?
The total solar eclipse will begin in Mexico at 11:07 a.m. PT and leave continental North America at 5:16 p.m. NT. From the time the partial eclipse first appears on Earth to its final glimpses before disappearing thousands of miles away, the celestial show will dazzle viewers for about 5 hours, according to timeanddate.com.
The length of the total solar eclipse at points along the path depends on the viewing location. The longest will be 4 minutes and 28 seconds, northwest of Torreón, Mexico. Near the center of the path, totality takes place for the longest periods of time, according to NASA.
Spectators will observe totality for much longer today than during the 2017 eclipse, when the longest stretch of totality was 2 minutes and 32 seconds.
The moon’s shadow seen on Earth today, called the umbra, travels at more than 1,500 miles per hour, according to NASA. It would move even more quickly if the Earth rotated in the opposite direction.
What is the longest a solar eclipse has ever lasted?
The longest known totality was 7 minutes and 28 seconds in 743 B.C. However, NASA says this record will be broken in 2186 with a 7 minute, 29 second total solar eclipse. The next total solar eclipse visible from parts of the U.S. won’t happen until Aug. 23, 2044.
