If the parties agree in their contract that the closing date for the sale of the parcel of proeprty is slated to be a certain date and the parties (buyer and seller) agree that the date to close is the agreed upon date to close escrow, the escrow company cannot unilaterally change the date of the agreed upon close because that date conflicts with some religious holiday it wishes to observe.If the escrow company is attempting to change the date of close unilaterally because of its whims, that is improper. You should contact your state's department or real estate about this turn of events and report the escrow company.Good luck.
