Why did SpaceX Crew-1 astronauts land in the dark after 167-day mission?

Elon Musk-led SpaceX safely returned with four astronauts from International Space Station after a 167-day mission on Sunday in a rare night splashdown. NASA said consistently calm nighttime weather at the splashdown site and ample moonlight made landing in the dark advantageous. Another advantage of landing in dark is avoiding disturbance from private boats, a safety risk.
