On the 27th of Adar I, 5752 (Monday, March 2, 1992), the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, suffered a disabling stroke while praying at the gravesite of the previous Rebbe, Rabbi Yosef Yitzchak of Lubavitch. On the same date two years later, the Rebbe lost consciousness following another stroke; three months later, on the 3rd of Tammuz 5754 (June 12, 1994), the Rebbe's soul ascended on high, orphaning a generation.

When the Holy Temple stood in Jerusalem, each Jew contributed an annual half-shekel to the Temple. The 1st of Adar marked the beginning of the collection of the shekalim. In commemoration, the Torah reading of the Shabbat that falls on or before Adar 1 is supplemented with the verses (Exodus 30:11-16) that relate G-d's commandment to Moses regarding the first giving of the half-shekel.
"Parshat Shekalim" is the first of four special readings added during or immediately before the month of Adar (the other three being "Zachor", "Parah" and "Hachodesh")

This Shabbat is Shabbat Mevarchim (“the Shabbat that blesses" the new month): a special prayer is recited blessing the Rosh Chodesh ("Head of the Month") of the upcoming month of Adar II, which occurs next Tuesday and Wednesday.
Prior to the blessing, we announce the precise time of the molad, the "birth" of the new moon. See molad times.
It is a Chabad custom to recite the entire book of Psalms before morning prayers, and to conduct farbrengens (chassidic gatherings) in the course of the Shabbat.

It is not so much that we need to be taken out of exile.
It is that we must take the exile out of ourselves.
What is exile? It is the belief that there is some place outside of G-d.
And that in that place, there are forces stronger than G-d.
And those forces will not allow you to do what your soul came here to do.
Fear no thing, no force, no being other than G-d. Do that which you must do as though nothing stands in your way.
Then you will have taken yourself out of exile. And G-d will complete the job.
