What is in the sky tonight, written for the date: planet positions, the Moon phase and the best window to look up. Every day gets its own page, and recent days stay listed below.
Each date gets its own page, built from real ephemeris positions rather than a template: where the Moon is and which phase it is in, which planets are retrograde that day, and how long after sunset the sky is dark enough to matter. The viewing window is not a fixed hour — it shifts through the year with the sunset time, which is why the same sign reads differently in March and September.
Of everything in the sky, the Moon changes fastest: it moves about thirteen degrees a day and completes a phase cycle in roughly twenty-nine and a half days. A bright Moon washes out faint objects, so a full Moon night and a new Moon night are genuinely different viewing conditions, and they set a different tone in astrological terms as well. The planet positions change far more slowly, which is why the sky page leads with the Moon and treats the outer planets as background.
Past dates stay online. If you photographed the sky, ran an observation session, or simply remember a night that felt unusual, opening the dated page is a way to check what was actually happening overhead. For the phase cycle in general rather than one night, start with the moon phases guide; for the retrograde pattern across the year see the retrograde calendar. Everything for the current date is collected on today's page.
The dated page gives the viewing window for that specific night, which depends on sunset time and how far below the horizon the Moon is. As a rule the darkest hour is between the end of astronomical twilight and moonrise, so if the Moon rises late, the early evening is the better slot.
It is written for a generic mid-northern latitude rather than a single city, so the phase, the retrograde status and the general viewing window are accurate anywhere, while exact rise and set times can shift by an hour or more depending on where you are.
The moon phases guide explains the full cycle and what each phase means generally. The Daily Sky page is dated: it tells you which phase applies tonight and what else is in the sky at the same time.
