A Jerusalem Resident Staying in Perazim on the 14th of Adar

I live in Jerusalem and will be in Beit Shemesh on Purim Sunday to work in a special education apartment, and I cannot leave the place. Do I need to fulfill the Purim mitzvot on this day? Am I obligated even though I will celebrate Purim in Jerusalem?

Hello and a good month

You did not specify in your question from when to when you intend to stay in Beit Shemesh. Therefore, I will write a few rules from which you can understand the law in your case:

A Jerusalem resident who arrives in 'Perazim' before the night of the 14th and intends to stay there until after dawn of the 14th is obligated in all the Purim laws of the 14th, meaning to hear the Megillah by day and night, send gifts, give gifts to the poor, and have a Purim feast. He must also say 'Al Hanisim' in his prayer.

A Jerusalem resident who arrives in 'Perazim' during the night of the 14th and intends to stay there until after dawn is obligated in the Purim laws of the 14th out of doubt. Therefore, he reads the Megillah without a blessing. And he is obligated out of doubt in all other mitzvot of the day.

A Jerusalem resident who arrives in 'Perazim' on the day of the 14th is not obligated in the Purim laws of the 14th.

Regarding the obligation on the 15th in Jerusalem: the rule is that even one who fulfilled the Purim mitzvot on the 14th is obligated in the Purim mitzvot on the 15th if on that day he is in Jerusalem.

Therefore, a Jerusalem resident who was in 'Perazim' on the 14th and returns home before the night of the 15th, or even during the night of the 15th, is again obligated in the Purim mitzvot on the 15th.

However, if he returns to Jerusalem on the 15th after dawn, he is exempt from Purim on the 15th.
