I know our haters recognize only the Julian date, rather than the Hebrew date, and so there is a lot of talk about that right now.
But we can focus on the zechus of Naftali ben Yaakov.
Devorah HaNeviah (the Biblical Prophetess) descended from Naftali and remained part of the Tribe of Naftali.
I don't know of any specific segulot, but it's always good to light a candle l'ilui nishmat Naftali ben Yaakov Avinu, zechuso tagen aleinu (for the soul-ascension of Naftali the son of Yaakov, may his merit protect us). And maybe read the part of Chumash which mentions Naftali ben Yaakov.
For a lovely article on Naftali ben Yaakov Avinu, please see:
