Is Birkat Hachamah any different this year because it falls on the morning before Passover?
The ceremony will be no different than any other Birkat Hachamah. However, because of the day’s many other Passover-related responsibilities – such as finishing and burning the chametz and preparing for the night’s Seder – it will probably be time-efficient and brief. Additionally, your local Chabad Center will likely combine this service with the customary Passover Eve Firstborn Feast and/or provide those attending with the opportunity to sell and burn their chametz.
