(, "Today is day ...") is a calendar for the Hebrew year of 5703 (1942-3), compiled by Rabbi Menachem Mendel Schneerson
at the behest of his father-in-law, Rabbi Yosef Yitzchok Schneersohn
, in the winter of 1942.
For each day, the calendar prescribed sections of Chumash
, and Tanya
for study that day; this practice is known in Chabad-Lubavitch
). Each day's portion of Chumash is studied with the corresponding Rashi
Each day's entry also noted historical events that happened on that day, or Lubavitcher customs associated with that day, and/or a short inspirational thought for the day, generally taken from the works of the sixth Lubavitcher Rebbe, Yosef Yitzchok Schneersohn
. In describing this work, Rabbi Yosef Yitzchak wrote: "A book that is small in format ... but bursting with pearls and diamonds of choicest quality ... A splendid palace of Chasidism."
The calendar was never reissued for subsequent years, but has been reprinted many times, and is still studied. In many Lubavitcher synagogues, the entry for each day is read aloud after the morning service.
The calendar's name is taken from the words used to open the recital of the daily psalm
in the Jewish morning prayer
service, which begins "Today is the nth day of the week..."
