business day 

A business day is a duration of time standardized to the seven-day work week, used to differentiate calendar days, based on a seven-day week, from the time period when a company is in operation.

In the Western world, Saturdays and Sundays are not counted as business/working days. In some Muslim countries and in Israel, this applies to Friday and Saturday.

Business days are common measurements in companies with time-sensitive services, such as shipping or payment processing. As an example, when sending a package with a shipping company such as FedEx, a shipment dispatched on a Thursday that is to be delivered in "two business days" will arrive on the following Monday.

In the United States of America, a work day is generally referred to as a weekday, not including Saturday and Sunday.

3-5 Business Days 

Commonly used phrase in Hypixel and Hypixel-related communities to represent something having an undetermined amount of time, that's likely to almost never happen or take a very long time.

It is said to have originated from the "Wizard Tower" of Hypixel SkyBlock where the NPC there has been replying with the dialogue: "Hmm...something appears to be broken. Give me 3-5 business days to fix!" for the past ~2.5 years and counting.

Friend: "When is x coming out?"
Me: "3-5 Business Days"
