Halakhic Map of Pesach - Laws & Timelines
An essential overview for when Erev Pesach falls on Shabbat.
CHAMETZ – THE CENTRAL PROHIBITION
What is Chametz?
Chametz is any food product made from wheat, barley, oats, rye, or spelt that has leavened (fermented) for 18 minutes or more. It includes bread, cakes, cookies, pasta, and beer.
Three Torah Prohibitions:
- Bal Yera’eh: One may not see chametz in their possession during Pesach.
- Bal Yimatzeh: One may not own chametz during Pesach.
- Akhilat Chametz: One may not eat chametz during Pesach.
Disposal of Chametz:
- Bedikat Chametz (Search): Done on the night of the 14th of Nissan, using a candle (or flashlight). A berakha is recited before the search.
- Bi’ur Chametz (Burning): Performed the following morning before the 6th halachic hour.
- Bitul Chametz (Nullification):
- Recited twice; the first declaration is said after the search.
- The second is recited after the burning – after disposing of any remaining chametz.

Mekhirat Chametz (The Sale of Chametz):
Chametz that cannot be consumed or destroyed before Pesach is sold to a non-Jew via a rabbi, through a formal legal sale.
PREPARATIONS BEFORE PESACH
Cleaning the Home:
All rooms, especially those where food is eaten or stored, must be cleaned thoroughly of chametz.

Kashering the Kitchen:
Utensils and surfaces that will be used for Pesach must be kashered properly. The method depends on how each item is normally used (direct heat, liquid, etc.).
EREV PESACH
🗓️ WEDNESDAY, APRIL 1, 2026
TA’ANIT BEKHOROT – FAST OF THE FIRSTBORN
It commemorates Hashem’s sparing the firstborn sons of the Israelites during the Tenth Plague in Egypt, when all Egyptian firstborns were struck down.
WHO FASTS, WHEN, AND WHAT TO DO
WHO FASTS?
- A firstborn male who is the first to open his mother’s womb (peter rechem) is obligated to fast. Likewise, a firstborn male from the father’s side is also obligated to fast.
- If the firstborn is a child, his father fasts on his behalf.
WHEN TO FAST?
- The fast is normally observed on the 14th of Nissan, but when Erev Pesach falls on Shabbat, it is moved earlier, as mentioned above.
HOW IT IS OBSERVED:
- Though it is technically a fast day, the widespread custom is for firstborns to attend a siyum—the festive completion of a Talmudic tractate—which exempts them from fasting for the remainder of the day.
TUESDAY NIGHT
- Bedikat Chametz
To be done on Tuesday night, starting at nightfall, once the stars appear. By that time, all cleaning must be completed in any area that may have contained chametz during the year.
- Care must be taken to set aside any chametz needed for the next day, so it is not lost.

WEDNESDAY, APRIL 1, 2026
- Bi’ur Chametz – Burning of Chametz
Chametz should be burned by the end of the fifth halachic hour on Wednesday, approximately 11:40 AM. After eliminating the chametz, the Kol Chamira nullification is recited at this time.
- Sale of Chametz
The sale of chametz is typically completed by 11:40 AM on Wednesday. One should consult the designated rabbinic authority for the precise time at which the sale will take place.
CHOL HA’MO’ED (INTERMEDIATE DAYS)
Work Restrictions:
Certain types of work are prohibited unless necessary for Yom Tov needs or to prevent financial loss. Ask a halakhic authority as needed.
Simcha and Activities:
These days are for spiritual growth, family time, and simcha (rejoicing). Matza is still eaten (though not obligatory if one prefers not to eat it), and chametz remains forbidden.
LAST DAYS OF PESACH
The 7th Day:
Commemorates Keriat Yam Suf (Splitting of the Sea). Full Yom Tov with festive meals, prohibited labor, a special Torah reading, and Hallel.
The 8th Day (in the Diaspora):
- Yizkor is recited.
- Some hold Moshiach’s Se’uda in the afternoon, with stories and singing about redemption.
