Tomorrow - Monday - is Erev Pessach; a busy day.
- Remember to light a 26-hour candle (or leave on a flame on the stove) so that you can light Yom-Tov candles on Tuesday evening if you live outside Israel.
- For details of the Fast of the Firstborn see Halocho #1804.
- Prepare the Salt Water for the Seder.
- Roast the Egg and Bone.
- Open the boxes of Matza, so as not to tear writing on Yom Tov.
- Ensure the wine bottles can be opened on Yom Tov without tearing any writing; else open them beforehand.
- Ensure Challa has been separated from the Matza to be used on Yom Tov.
- Make the Charoset.
One does not say מִזְמוֹר לְתוֹדָה nor לַמְנַצֵּחַ from Erev Pesach until Isru Chag.
One may not eat Chametz after 1/3 of the day, and then - within the hour - one needs to burn one's Chametz and say Kol Chamira declaring all Chametz one owns to be ownerless like dust.
Work that may not be done on Chol Hamo'ed may not be done on Erev Pesach after noon. See Halocho #1311, #1312 and #1320 for details.
One may not eat Matza on Erev Pessach.
