On any day that has a CIvil Twilight, for a start.

No, that may be used to define the time at which a task will end even
if the glider has not landed, but it does not define a maximum task

maximum allowed duration between the time of starting and the end of
the scoring flight.

Rule 10.1.10
Finish closes - At contest sunset time

therefore task end = Finish close

Contest sunset time defined as

Rule 10.1.8
Contest sunset - the CD shall designate a contest sunset time,
which shall be approximately 10 minutes prior to the earliest time of
sunset at the contest site during the period of the contest.
