Golden hour in Kolkata in September

Kolkata lies at 22.57° N, in the tropics, where the sun climbs steeply and sets fast. Its longest measured day falls on Thu 18 June 2026 with 13h 31m of daylight, and its shortest on Fri 18 December 2026 with 10h 45m — a difference of 2h 46m between the two extremes.

Evening golden hour in Kolkata runs for roughly 32 minutes at the height of summer, 30 minutes around the March equinox and 33 minutes at midwinter. The warm window is actually widest in the colder months, which makes winter evenings unusually forgiving here.

The sun sets toward 296° WNW in late June and toward 245° WSW in late December, a shift of about 51° in where the last light lands — worth checking before committing to a west-facing viewpoint. In Kolkata, the sky reaches full darkness between evening and morning twilight year-round.
