Sunset and nigh flying definitions

Yes, 91.209 is the sunset/sunrise position lighting requirement for all
aircraft. But night is twilight/twilight, and there are no extra
restrictions for night flight in gliders in Part 91. There probably are
restrictions in the specific airworthiness certification, but not in
general.

Technically, this is not a requirement for gliders. See the full
heading:

91.205: Powered civil aircraft with standard category U.S.
airworthiness certificates: Instrument and equipment requirements.

Note that this is for *powered* aircraft, so would apply to
motorgliders, but not pure gliders. However, if the glider has a
standard airworthiness certificate, it is probably limited to VFR day
only. If it is experimental, it probably has the same restriction; if
not, there would be specific requirements for night flying equipment
which would probably also include cockpit lighting in addition to
position and possibly anti-collision lights.
