I have this formula which works fine when put into individual cells in a column:
=OR(AND(AND(D2:D, WEEKDAY(NOW()) = 1),D2:D <>""),
AND(AND(E2:E, WEEKDAY(NOW()) = 2),E2:E <>""),
AND(AND(F2:F, WEEKDAY(NOW()) = 2),F2:F <>""),
AND(AND(G2:G, WEEKDAY(NOW()) = 2),G2:G <>""),
AND(AND(H2:H, WEEKDAY(NOW()) = 2),H2:H <>""),
AND(AND(I2:I, WEEKDAY(NOW()) = 2),I2:I <>""),
AND(AND(J2:J, WEEKDAY(NOW()) = 2),J2:J <>"")
)
However I can't seem to get it to work in arrayformula:
=ARRAYFORMULA(IF(LEN(A2:A),
OR(AND(AND(D2:D, WEEKDAY(NOW()) = 1),D2:D <>""),
AND(AND(E2:E, WEEKDAY(NOW()) = 2),E2:E <>""),
AND(AND(F2:F, WEEKDAY(NOW()) = 2),F2:F <>""),
AND(AND(G2:G, WEEKDAY(NOW()) = 2),G2:G <>""),
AND(AND(H2:H, WEEKDAY(NOW()) = 2),H2:H <>""),
AND(AND(I2:I, WEEKDAY(NOW()) = 2),I2:I <>""),
AND(AND(J2:J, WEEKDAY(NOW()) = 2),J2:J <>"")
),""))
Here is the sheet shared so you can copy it: https://docs.google.com/spreadsheets/d/1TR-ayKtfOFC2LtQoIm8kzt7keTsyrqgxP0ZY9JVDcOs/edit?usp=sharing
[UPDATE:] My original formula had another error. PlayerO solved the AND OR issue but carried forward my error. Here is the corrected code that worked for my situation:
={"VaildDay";ARRAYFORMULA(IF(LEN(A2:A),
((((E2:E)*(WEEKDAY(NOW())=1))*(E2:E<>""))+
(((F2:F)*(WEEKDAY(NOW())=2))*(F2:F<>""))+
(((G2:G)*(WEEKDAY(NOW())=3))*(G2:G<>""))+
(((H2:H)*(WEEKDAY(NOW())=4))*(H2:H<>""))+
(((I2:I)*(WEEKDAY(NOW())=5))*(I2:I<>""))+
(((J2:J)*(WEEKDAY(NOW())=6))*(J2:J<>""))+
(((K2:K)*(WEEKDAY(NOW())=7))*(K2:K<>"")) = 1, ))
