i have two columns (Start Date, End Date) and i want a code that changes the color of both their cells to red if the start date and end date contained any date located in another sheet
I tried using conditional formatting using this rule: =AND(C2<=Holidays!$A$2:$A$15,D2>=Holidays!$A$2:$A$15)

Tested out the below formula for myself and think it should work! Effectively rather than a simple AND statement, since we're comparing against an array of values rather than single cells, we need to use some handy array formulas. This post gives a good breakdown of what's going on under the hood: https://exceljet.net/formula/index-and-match-with-multiple-criteria
Apply this formula in conditional formatting, assuming the range you're formatting starts at C2.
=SUM((Holidays!$A$2:$A$15>$C2)*(Holidays!$A$2:$A$15<$D2)) > 0
Also, wanted to call out the absolute references specified for columns. I've specified **$**C2 and **$**D2 in my formula, which means that no matter which cell in your conditional formatted range it'll evaluate off the values in column C and D. In your current formula, cell C2, would evaluate on C2 and D2, but cell D2 would then evaluate off D2 and E2. This'd be why when you tried the manual formatting only the start date cells (column C) were formatting correctly.
Hope this helps!
Update::
If you had a table format like in the attached screenshot, you would apply the conditional formatting formula:
=SUM((Holidays!$A$2:$A$15>$C2)*(Holidays!$A$2:$A$15< $D2)) > 0
To cell range $C$2 : $D$3
If you're changing the cell range (say you wanted to apply to $C$10 : $D$14), you'd just change the $C2 and $D2 in the formula --> $C10 and $D10.
