- Release all keys

**Explaining array formula in cell B12**

**Step 1 - Create dates**

ROW(INDIRECT(B4&":"&B5))

becomes

ROW(INDIRECT(40544&":"&40603))

becomes

ROW(40544:40603)

and returns

{40544; 40545; 40546; 40547; 40548; 40549; 40550; 40551; 40552; 40553; 40554; 40555; 40556; 40557; 40558; 40559; 40560; 40561; 40562; 40563; 40564; 40565; 40566; 40567; 40568; 40569; 40570; 40571; 40572; 40573; 40574; 40575; 40576; 40577; 40578; 40579; 40580; 40581; 40582; 40583; 40584; 40585; 40586; 40587; 40588; 40589; 40590; 40591; 40592; 40593; 40594; 40595; 40596; 40597; 40598; 40599; 40600; 40601; 40602; 40603}

*Step - 2 Check if date is a holiday*

MATCH(ROW(INDIRECT(B4&":"&B5)), $B$8:$B$9, 0)

becomes

becomes

**Step 3 - Filter non holiday dates**

Hi Oscar... I'm trying to adapt your formula to determine in a date range of arrival dates, how many people I will have in a determine date. For example if I have 2 people arriving 05/14/17 and leaving 05/16/17 but also have 3 people arriving 05/15/17 leaving 05/17/18.

I need to know how many people I have in house for each day... 14 - 2 guests, 15-5 guests, etc.

Any ideas?

Thanks in advance!
