Browse the listed events by month or filter for meteor showers, Moon events, and planetary events. Dates are approximate calendar dates, and the countdown uses local midday on the listed date because the exact event time can vary by time zone.
Viewing conditions vary with your location, horizon, weather, and light pollution. Eclipse paths and meteor-shower rates differ by region and sky conditions, so confirm the event and its visibility for your location before planning an observation.
Reference calendars: U.S. Naval Observatory Moon phases, U.S. Naval Observatory seasons, NASA skywatching guides, NASA eclipse information, and the American Meteor Society meteor shower calendar.
