Tonight from Beijing

Tonight in Beijing, China, the sun sets at 19:46 local time and astronomical darkness — when even the faintest stars become visible — arrives at 21:49. The moon is in first quarter phase, 57% illuminated. No major planets are above the horizon at sunset. Sunrise comes at 04:46.

At mid-latitudes, night length varies substantially with season; summer offers shorter darkness, winter the longest. Polaris sits roughly at this latitude above the northern horizon, making it a permanent compass for navigation. The Big Dipper, Cassiopeia, and the northern circumpolar stars never set.
