Eclipse Calculator

Solar eclipses happen when the Moon passes between Earth and the Sun; lunar eclipses happen when the Moon passes through Earth's shadow. This calculator lists eclipses for your selected year and shows times in your chosen location's timezone. Types: • Solar: Total—the Sun is fully covered; partial—only part of the Sun is covered; annular—the Moon is farther away, so a thin ring (annulus) of the Sun remains. • Lunar: Penumbral—the Moon passes through Earth's faint outer penumbra; partial—part of the Moon enters the dark umbra; total—the full Moon lies in the umbra. How to read the timings: • Visibility at your location: Labels show whether the eclipse is visible where you are. Geometry, sunrise/sunset, and moonrise/moonset all matter; a global eclipse may still be invisible from your site. • Local clock times: We use your location's timezone (including typical DST rules). Clear skies and an open horizon still affect what you actually see. • Religious / ritual use: Traditions differ. Many do not treat penumbral lunar eclipses like umbral ones. Solar rules often depend on the eclipse being seen after sunrise or finishing before sunset. The notes under each eclipse summarize how this app marks those cases. • Contacts and phases: Solar listings may show first through fourth contact; lunar listings use penumbral and umbral begin/end—these mark the astronomical phase boundaries.
