# EDD (estimated delivery date)

An estimated delivery date (EDD) is the shopper-facing date a delivery is expected to arrive, computed from fulfillment location, carrier service levels, transit times, and cutoffs. The date changes as those inputs change: the EDD shown after a cutoff passes may differ from the one shown that morning. Producing it is the job of [order promising](/content/order-promising/index.html).
