Sefer Ha’mitzvos Ha’Katzar (The concise book of mitzvos) By the Chofetz Chaim
This book lists the Torah mitzvos that can be observed today
First Section – the Positive Commandments
27. It is a positive commandment to rest from work on the Seventh Day of Passover
As it states in Vayikra (Leviticus) 23:8, “On the seventh day, it shall be made holy.” This law is the same as the first day of Passover, as written above (mitzvah #25).
This applies in all places and at all times for men and for women.
