Hayom Yom — From Day to Day
Hebrew: הַיּוֹם יוֹם — “From day to day” | Compiled: 5703/1943 | Author/Editor: The Rebbe (Rabbi Menachem Mendel Schneerson)
What Is Hayom Yom?
Hayom Yom is a small but extraordinary book: a calendar-diary of Chabad teachings and customs, one entry for each day of the Jewish year. Compiled by the future Rebbe at the request of the Frierdiker Rebbe (Rabbi Yosef Yitzchak Schneersohn) for Rosh Hashanah 5703/1943, it draws from the oral and written traditions of Chabad Rebbes going back to the Baal Shem Tov.
Each daily entry typically contains:
- A short Chassidic teaching or saying (ma’amar fragment, sicha excerpt, or maaseh — story)
- A custom specific to that day or season
- A halacha particularly relevant to Chabad practice
The entries are terse and dense — a few sentences, sometimes a single sentence — yet they have the quality of concentrated light. Generations of Chassidim have found that a single Hayom Yom entry, studied carefully, can sustain an entire day of avodah.
The Commissioning
The Frierdiker Rebbe was in New York, having escaped Europe. He asked his son-in-law (the future Rebbe) to compile a Chassidic calendar — a sefer that would give Chassidim throughout the world a shared daily rhythm of teaching and practice. The future Rebbe drew on his encyclopedic knowledge of Chabad tradition, selecting and editing entries that would serve as chiyus (vitality) for the Chassid’s daily life.
The Hayom Yom was published just in time for Rosh Hashanah 5703, and it immediately became one of the most beloved and used books in the Chabad library.
The Daily Rhythm
Many Chassidim begin their day with the Hayom Yom entry — after morning prayer but before the demands of the day set in. The entry serves as a cheshbon (orientation point) and a hachlata (resolution) for the day. Some Chassidim know the entire Hayom Yom by heart — the accumulation of daily learning over many years has embedded it in their consciousness.
The Rebbe would often begin farbrengens by citing the Hayom Yom entry for that day — placing the gathering in the context of the ongoing daily practice that Hayom Yom anchors.
As a Window into Chabad Culture
Hayom Yom is also the best single-volume introduction to Chabad customs and hashkafah (worldview). Entries address:
- How a Chassid should begin his day (waking with Modeh Ani, immediate focus on avodah)
- The customs of Shabbos, Yom Tov, and special days
- The Chabad approach to prayer, Torah study, and interaction with others
- Teachings of each of the Chabad Rebbes in their own voices
A Beloved Quote
One of the most cited entries (Adar 1): “The world was created for my sake” — each person is a world. Another (Kislev 4): “The first lesson that a Jew must internalize is that he has a soul — a divine soul — and that the soul’s single desire is to cleave to its source.”
