61.57 does not define "night"
1.1 defines "night"
61.57 says your in the dark "night" landings have to be 1hr after sunset, to
1hr before sunrise.
Definitions are not in the 61 or 91 series of the regs
Definitions are in Part 1.1

It's helpful to remember that the official definition of night is one
hour after civil twilight to one hour before civil dawn (by which time
it is often black as ..well..night.)

Brian, Wrong answer. FAR 1.1 defines "night" as the end of evening
civil twilight to the beginning of morning civil twilight as published
in the American Air Almanac, converted to local time. The American Air
Almanac is now maintained by the US Naval Observatory.

For my location today, Morning Civil Twilight started at 5:42am and
Sunrise at 6:09am, 27 minutes later.
Sunset is 7:14pm and End of Civil Twilight is 7:40pm, 26 minutes later.

Not the "hour" that you suggest.

The "aircraft lighting" requirement is from Sunset to Sunrise
(excluding Alaska). 91.209, Not twilight to twilight.

BT - wrong answer: right back at ya! :-)

If you need to get night current to carry passengers, follow the
definition of night as described in FAR 61.57(b), which is the "period
beginning one hour after sunset and ending one hour before sunrise."

Yes, there really are several different definitions in the FARs...

Brian... but that is not the definition of "night"....

Duh!
'follow the definition of night as described in FAR 61.57(b), which is the
"period beginning one hour after sunset and ending one hour before
sunrise."'

' Yes, there really are several different definitions in the FARs...'

What don't you understand about FAR 61.57(b) Definition of night?
