Let's say an unexpected emergency comes up and you, the seller, must now stay at your property longer than what you agreed to when you initially accepted the buyer's offer to purchase your home.
You and the buyer, during escrow, can make an amendment to the contract to change the day when you hand over possession of your home.
As long as it's put in writing in a amendment and signed off on by all parties involved, possession of the property can change hands on whatever day everyone agrees to.
