When showing future inventory dates for devices, what does "week of" mean?

When you see a future inventory date showing for a device, "week of" means that the device could stock up anywhere during the entire week (Sunday to Sunday) from the date that is given. For example, if the future inventory date says "More unites week of 19 Dec 2021", this means we expect to have more inventory available anywhere from December 19 to December 26.
