I have in my hands a luach for Eretz Yisrael for this year that gives three sets of Purim practices. This is my translation. All (parentheses) are in original; [brackets] are mine. In quotes are the original; outside of quotes are a paraphrase.
- "villages that were not surrounded by walls at the time of Yehoshua bin Nun" - Purim is 14 Adar. "The moshavot and the new cities, their rule is like all the unwalled cities and their Purim is only on the 14th."
- "the old cities in Eretz Yisrael like Jaffa, Lod, Akko, Tiberias, Tzefat, Haifa, Beersheva, and Hebron (Shechem and Gaza) (even though not all of these cities have a source for this rule, as we have explained in מק"א [?] -- leave Israel alone with the minhag that they have practiced) they are in a doubtful status of having been surrounded by walls from the time of Yehoshua bin Nun" -- do everything on 14 Adar. They used to also do Al Hanisim and the Torah reading on 15 Adar, but don't anymore. [Presumably because it's Purim Meshulash this year], do another seudah and mishloach manot on Sunday, 16 Adar. [It doesn't say whether they would read megillah again on 15 Adar in a normal year, since that's a moot question this year. Does anyone know?]
- "Jerusalem, which was definitely surrounded by walls at the time of Yehoshua bin Nun" - [normally 15 Adar. This year,] Purim Meshulash.
