The Holy Temple, which took seven years to build, was completed by King Solomon during the month of MarCheshvan (I Kings 6:38), although not necessarily on this exact day. (Its dedication, however, was postponed until Tishrei of the following year—see calendar entry for 8 Tishrei). The First Temple served as the epicenter of Jewish national and spiritual life for 410 years, until its destruction by the Babylonians in 423 BCE.
Today is the second of the two Rosh Chodesh ("Head of the Month") days for the month of Cheshvan (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.

The month of Cheshvan is also called "Mar-Cheshvan." Mar means "bitter" -- an allusion to the fact that the month contains no festive days. Mar also means "water", alluding to the month's special connection with rains (the 7th of Cheshvan is the day on which Jews begin praying for rain (in the Holy Land), and the Great Flood, which we read about in this week's Torah reading, began on Cheshvan 17th).

On the outside, Torah is water. On the inside, it is fire.
The text, the instructions, the practical side of Torah--that is water.
People come to water. When they are thirsty, they gather around.
But what if you have no thirst for Torah? What if you find the water cold? What if dos and don’ts don’t excite you?
Then you must enter within, to the hidden meanings, to the mysteries of Torah. To its fire.
But what if you fear fire? What if you fear the unknown, the spiritual, the transcendental?
Then, you must know: This fire does not burn. It ignites the soul. It is life itself. In truth, it is your fire.
Enter within. Do not be afraid. “G-d, your G-d is a consuming fire.”
