Penumbral
The Moon passes through Earth's outer shadow. The dimming can be very subtle, and shallow events may be impossible to notice.
Lunar Eclipse Planner
Explore upcoming and past lunar eclipses, find their local times and see which phases may be above your horizon.
Local times follow the chosen time zone, including daylight saving changes. Use a time zone such as Europe/London, America/New_York or UTC. Coordinates are used for this calculation and are not saved by this tool.

Visibility estimates include events where only the beginning or end is above your horizon. “Greatest eclipse” is the global peak, which may occur while the Moon is below your horizon.
Three ways the Moon meets Earth's shadow
Partial
Part of the Moon enters Earth's dark inner shadow, producing a visible dark bite in its disc.
Total
The whole Moon enters the inner shadow. It can glow copper or red as sunlight filtered through Earth's atmosphere reaches its surface.
You can watch a lunar eclipse with your eyes, binoculars or a telescope. Clouds, buildings and hills can hide the view even when the Moon is above the calculated horizon.
Source: NASA GSFC catalogue, Fred Espenak and Jean Meeus. Greatest-eclipse times are converted from catalogue dynamical time using its predicted ΔT and shown as approximate UTC. Other stage boundaries are estimated by centring the catalogue durations on greatest eclipse; actual contacts are not perfectly symmetric. Local visibility uses ChronoWaves' approximate Moon and Sun positions with one-minute sampling, lunar parallax and a standard horizon allowance. For precise contact times and visibility, open the linked NASA diagram. Future UTC predictions become less certain further ahead.
