Dear Rabbi Simon,
What’s the latest time one can light his or her Chanukiah?
Many thanks,
Meir
Dear Meir,
Nowadays that people are out and about until quite late, depending on the street where you live, in extremis one may light until at least 10:00pm, or even midnight or later (eg on Finchley Road). Indeed, in accordance with the minhag that we light indoors, one can even fulfil the mitzvah of “publicising the miracle” through the participation of another member of the household (ie, as long as s/he has not yet gone to bed). Nevertheless, it is best to light promptly at nightfall or as soon as achievable thereafter.
I hope this is helpful.
Best wishes for a luminous Chanukah
Rabbi Rashi Simon
