On the first of Shevat in the year 2488 from creation, Moses convened the Jewish people and began the 37-day "review of the Torah" contained in the Book of Deuteronomy, which he concluded on the day of his passing on Adar 7 of that year.
Today is Rosh Chodesh (“Head of the Month”) for the month of Shevat.
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.

How Does a Jewish Woman Celebrate Rosh Chodesh?
Thoughts can give life. Thoughts can kill.
For example, a soldier. The Torah commands a soldier at war, “Do not allow your heart to weaken. Do not fear. Do not panic.”
Imagine this: An army is racing towards you. Your eyes have witnessed their savagery. How can you command your heart not to fear?
Maimonides explains: Don't think those thoughts and you will not fear. Dodge them as you dodge a flying arrow.
Because such thoughts threaten not only your life, they endanger the entire nation.
A soldier must think only one thought: What must I do right now?
Today, we are all soldiers.
