Today is the first of the two Rosh Chodesh ("Head of the Month") days for the month of "Adar II" (when a month has 30 days, both the last day of the month and the first day of the following month serve as the following month's Rosh Chodesh).
Special portions are added to the daily prayers: Hallel (Psalms 113-118) is recited -- in its "partial" form -- following the Shacharit morning prayer, and the Yaaleh V'yavo prayer is added to the Amidah and to Grace After Meals; the additional Musaf prayer is said (when Rosh Chodesh is Shabbat, special additions are made to the Shabbat Musaf). Tachnun (confession of sins) and similar prayers are omitted.
Many have the custom to mark Rosh Chodesh with a festive meal and reduced work activity. The latter custom is prevalent amongst women, who have a special affinity with Rosh Chodesh -- the month being the feminine aspect of the Jewish Calendar.

Blind faith believes that which it is told, because it wants to believe.
Intellect believes that which it understands, because it wants to attain understanding.
Wisdom believes that which is true, because it is true.
Wisdom doesn’t have to fit that which some self-serving faith wishes to believe. Neither does it await the approval of intellect to say, “This can be understood.”
Wisdom is a power of vision, the power to see “that which is” without attempting to fit it into any mold. It is not blind at all, but it is nevertheless faith beyond reason. Because when you see the truth before you, all the reason in the world can't convince you otherwise.
Wisdom, therefore, is the only channel by which an Infinite G‑d may enter.
