Tell me where you are first — every number on this page depends on it, the sky most of all: the same lunar eclipse that's overhead in Seattle may happen before the Moon has even risen in Miami.
Sky events are computed here directly from your latitude and longitude (ephemeris by astronomy-engine), with no third-party API in the loop — so nothing here breaks when some service shuts down, and it needs nothing beyond a connection. The "per hour" figure for meteor showers is an estimate that folds in radiant altitude, moonlight, twilight and peak falloff; what you actually see also depends on light pollution and your patience.
