Experience the Solar Eclipse With San Mateo County Libraries

Join San Mateo County Libraries as we experience the solar eclipse on the morning of Monday, April 8.

During a solar eclipse, those of us on Earth watch the sky grow dim and dark as the moon passes between us and the sun. The 2024 solar eclipse passes eastward from Mexico, across the United States and through Canada. San Mateo County won’t see a total solar eclipse—which is a brief moment when the moon completely blocks the sun—but we will have a chance to enjoy a partial eclipse from 10:13 AM to 12:15 PM. To learn more about when the eclipse will be visible in different parts of North America, explore this interactive map, opens a new window from NASA, opens a new window.

Enjoy the Eclipse With Our Free Glasses

To safely enjoy an eclipse, it’s essential to use specialized eye protection. It’s not safe to look directly at the sun, and regular sunglasses or camera lenses are not designed to ward off the sun's powerful rays. We are excited to offer free eclipse glasses, distributed from our 13 locations on a first come, first served basis while supplies last.

Still have glasses from a previous eclipse? You can test if they are still safe to wear by holding them up to the light. If you see even the slightest hint of light shining through, those glasses are not safe! When in doubt, throw them out.

Remember, never look directly at the sun or an eclipse without protection specifically designed to protect your eyes. We want you to be able to enjoy solar and lunar eclipses for decades to come!
