R. Shlomo Kluger, rabbi of Brody, was one of the renowned halachic authorities of his day. He was a prolific writer, authoring over 100 books.
Today is the first of the two Rosh Chodesh ("Head of the Month") days for the Hebrew month of "Tammuz" (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.

Nothing is greater than peace. Even when you are 100% right, and you know your spouse is 100% wrong, you can still give in for the sake of peace.
Better a difficult peace than an easy quarrel.
