That restriction applies only between sunset and sunrise.

More like between 30 minutes after sunset and 30 minutes before sunrise,
roughly, the rule of thumb for night ops in the continental US, not to be
confused with the one hour after sundown rule for logging night flight time.

Err, 'night' in the FAR is defined in 14 CFR Part 1 and it's based on
civil twilight.

The SVFR regulations in 91.157(b)(4) says sunset-sunrise, not "night",
so the other poster was exactly right.

It's 61.57(b) (night currency) that uses the "hour after sunset".

The ICAO definition is when the center the sun is 6 degrees or more below
the horizon

Which is the definition of the end of civil twilight.
