- Cities that had a wall around them at the time of Yehoshua bin Nun read the Megilla on the 15th of Adar. This applies to adjacent villages up to a mil distance as well. Also to villages that are far but high up and can see the city. (ShA , )
- All other settlements read the Megilla on the 14th of Adar. (ShA )
- If there is a doubt about the status of a settlement, read the Megilla both on the 14th and the 15th, saying the berachos only on the 14th. (ShA )
- A Bnay Braker (example of a “ben ir”) who travels to Yerushalayim with the intention to return to Bnay Brak before the morning of the 15th reads the Megilla on the 14th only. Even if his plans later changed and he stayed in Yerushalayim until the morning. However, if he originally planned to stay in Yerushalayim until the morning of the 15th he is obligated to read on the 15th even if he returns to Bnay Brak without having read yet. He will read in Bnay Brak on the 15th of Adar. (MB )
- A Yerushalmi (example of a “ben krach”) who travels to Bnay Brak and plans to return before the morning of the 14th – he will read on the 15th of Adar. Even if his plans change to stay in Bnay Brak until the morning of the 14th, he won’t be obligated to read on the 14th. However if he originally plans to be in Bnay Brak on the morning of the 14th and he actually did end up there in the morning of the 14th, he will need to read on the 14th. If he returns to Yerushalayim before reading, he will read the Megilla on the 14th in Yerushalayim. (MB )
- If you are in an uninhabited place for Purim, read the Megilla on the 14th. (Rama )
