Average data based on weekday or weekend

Here I have two formulas that can quickly average values based on weekday or weekend in another cell.

Select a cell which you will place the formula and result at, type this formula =SUM((WEEKDAY(A2:A20, 2)<6)*(B2:B20))/SUM(1*(WEEKDAY(A2:A20, 2)<6)), and press Shift + Ctrl + Enter keys simultaneously.

Tip:

1. If you want to average values by weekend, you can use this formula =SUM((WEEKDAY(A2:A20, 2)>5)*(B2:B20))/SUM(1*(WEEKDAY(A2:A20, 2)>5)), and press Shift + Ctrl + Enter.

2. In the formulas, A2:A20 is the range of date cells, B2:B20 is the range of numbers you want to average.
