My daughter asked an interesting sha'alah (religious question)...
I want to give mishloach manot (the gifts of Purim, a religious obligation to give on Purim day) to a friend in Jerusalem. We don't live in Jerusalem and celebrate Purim on the 14th of Adar - but Jerusalem celebrates on the 15th of Adar. Do I fulfill my obligation by giving her on the 14th?
This is a halachic (Jewish religious law question) which can only arise nowadays in Israel. The halacha of Purim is that walled cities - cities that were walled at the time of Yohoshua bin Nun (Joshua) - celebrate a day later than unwalled cities. Unwalled celebrate on the 14th, and walled on the 15th, Jerusalem on the 15th, most other cities in Israel on the 14th (there's a few other places that celebrate on the 15th as well).
Nowadays, you can live in Mevetzeret Tziyon and be 10 minutes from friends in Jerusalem (by car), so it's a practical question.
I asked this sha'alah of the halacha rav at Rabbi Nati's yeshiva. His answer was:
A person who lives outside of Jerusalem cannot fulfill their obligations of Mishloach Manot by giving to someone in Jerusalem on Purm - the 14th of Adar. (And of course, if they gave on the 15th of Adar - Shushan Purim when it is celebrated in Jerusalem, the time of fulfilling the obligation has passed for them.)
