On the holiday of Passover, we are commanded not to have any chametz in our possession. Any food that is made out of grain that has been allowed to rise (ferment) is chametz. Common chametz items include bread, cakes, cereals, pastas, many liquors, and more. Any chametz that was in the possession of a Jew during Passover is forbidden, even after Passover ends. This applies even if the chametz is locked up and out of sight, therefore all chametz that will not be eaten or burned before Pesach and all chametz utensils that will not be thoroughly cleaned by then should be stored away and sold.

Chabad facilitates the sale of Chametz service here at no charge.
 

Monday Times:

Finish eating chametz by 10:50 AM
Finish burning & selling Chametz by 11:58 AM

Passover ends: Tuesday, April 30 at 8:39 pm  
(you can use your chametz once again right after Passover ends)
