In Yerushalayim (and other walled cities from the time of Yehoshua bin Nun), some of Purim’s obligations are observed today.
Do not say Av Harachamim nor Tzidkas’cha.
Increase in festivities and simchah today as well.
It is customary for the baal korei to lower his voice slightly when reading the story of the chet ha’egel.
The haftorah for Parshas Ki Sisa begins with the words Vayishlach Ach’av (I Melachim 18:20).
In a year with a similar kevius, the Rebbe suggested that in order to remember and unite with the Jews of Yerushalayim, who are still celebrating parts of Purim this Sunday, Jews all over the world should add in joy today.
This should be done through adding in Torah learning (which “gladdens the heart”).
This should also be done through making other Jews happy.
If proper or needed, make other Jews happy through giving them Mishloach Manos and Matanos La’evyonim (in addition to Purim day, when it is a mitzvah.)
Special emphasis should be placed on arranging gatherings—especially for children—with the goal of strengthening Yiddishkeit, joyfully.
When saying shnayim mikra, say both the haftorah for Parshas Vayakhel, and for Parshas Parah.
