As per the Talmud, the month of Kislev marks the onset of the winter season in the Holy Land and is the third month of the "Season of the Rains."

For the first time since suffering a major heart attack five weeks earlier, on the eve of Shemini Atzeret, the Rebbe left his office in 770 Eastern Parkway and returned to his home, signaling his recovery. Chassidim all over rejoiced at the good news.
From that day on, the Rebbe redoubled his efforts on behalf of the Jewish nation and all of humanity, and for the dissemination of Torah and chassidism. From then on, the first of Kislev is celebrated as a day of thanksgiving and rejoicing.

Today is Rosh Chodesh ("Head of the Month") for the month of Kislev.
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.

There are multiple universes, and you can travel to any one of them on any day.
There is one universe in which you stand at the center while all else orbits about you.
There’s another universe where someone else stands at the center and everything orbits around him or her.
And both are true, real universes, because each of us truly is responsible for the destiny of our world, as the Mishnah says, “Every human being must say, ‘The universe was created for me to repair.’”
The equipment you need for your journey is already yours. Because if you can understand that you are the center of your world, you can understand how the other guy is the center of his.
Just adjust your mind, open your heart, and envision the universes of these other beings.
Then go treat them accordingly.
Yes, you can become a multiverse trekker without even walking out your front door. You don’t even have to leave yourself behind.
